4.1. Parameters

Bugzilla is configured by changing various parameters, accessed from the Parameters link, which is found on the Administration page. The parameters are divided into several categories, accessed via the menu on the left.

4.1.1. Required Settings

The core required parameters for any Bugzilla installation are set here. urlbase is always required; the other parameters should be set, or it must be explicitly decided not to set them, before the new Bugzilla installation starts to be used.

urlbase

Defines the fully qualified domain name and web server path to this Bugzilla installation. For example, if the Bugzilla query page is http://www.foo.com/bugzilla/query.cgi, the urlbase should be set to http://www.foo.com/bugzilla/.

ssl_redirect

If enabled, Bugzilla will force HTTPS (SSL) connections, by automatically redirecting any users who try to use a non-SSL connection. Also, when this is enabled, Bugzilla will send out links using sslbase in emails instead of urlbase.

sslbase

Defines the fully qualified domain name and web server path for HTTPS (SSL) connections to this Bugzilla installation. For example, if the Bugzilla main page is https://www.foo.com/bugzilla/index.cgi, the sslbase should be set to https://www.foo.com/bugzilla/.

cookiepath

Defines a path, relative to the web document root, that Bugzilla cookies will be restricted to. For example, if the urlbase is set to http://www.foo.com/bugzilla/, the cookiepath should be set to /bugzilla/. Setting it to / will allow all sites served by this web server or virtual host to read Bugzilla cookies.

4.1.2. General

maintainer

Email address of the person responsible for maintaining this Bugzilla installation. The address need not be that of a valid Bugzilla account.

utf8

Use UTF-8 (Unicode) encoding for all text in Bugzilla. Installations where this parameter is set to off should set it to on only after the data has been converted from existing legacy character encodings to UTF-8, using the contrib/recode.pl script.

Note

If you turn this parameter from off to on, you must re-run checksetup.pl immediately afterward.

shutdownhtml

If there is any text in this field, this Bugzilla installation will be completely disabled and this text will appear instead of all Bugzilla pages for all users, including Admins. Used in the event of site maintenance or outage situations.

announcehtml

Any text in this field will be displayed at the top of every HTML page in this Bugzilla installation. The text is not wrapped in any tags. For best results, wrap the text in a <div> tag. Any style attributes from the CSS can be applied. For example, to make the text green inside of a red box, add id=message to the <div> tag.

upgrade_notification

Enable or disable a notification on the homepage of this Bugzilla installation when a newer version of Bugzilla is available. This notification is only visible to administrators. Choose disabled to turn off the notification. Otherwise, choose which version of Bugzilla you want to be notified about: development_snapshot is the latest release from the master branch, latest_stable_release is the most recent release available on the most recent stable branch, and stable_branch_release is the most recent release on the branch this installation is based on.

4.1.3. Administrative Policies

This page contains parameters for basic administrative functions. Options include whether to allow the deletion of bugs and users, and whether to allow users to change their email address.

allowbugdeletion

The pages to edit products and components can delete all associated bugs when you delete a product (or component). Since that is a pretty scary idea, you have to turn on this option before any such deletions will ever happen.

allowemailchange

Users can change their own email address through the preferences. Note that the change is validated by emailing both addresses, so switching this option on will not let users use an invalid address.

allowuserdeletion

The user editing pages are capable of letting you delete user accounts. Bugzilla will issue a warning in case you’d run into inconsistencies when you’re about to do so, but such deletions still remain scary. So, you have to turn on this option before any such deletions will ever happen.

last_visit_keep_days

This option controls how many days Bugzilla will remember that users have visited specific bugs.

4.1.4. User Authentication

This page contains the settings that control how this Bugzilla installation will do its authentication. Choose what authentication mechanism to use (the Bugzilla database, or an external source such as LDAP), and set basic behavioral parameters. For example, choose whether to require users to login to browse bugs, the management of authentication cookies, and the regular expression used to validate email addresses. Some parameters are highlighted below.

auth_env_id

Environment variable used by external authentication system to store a unique identifier for each user. Leave it blank if there isn’t one or if this method of authentication is not being used.

auth_env_email

Environment variable used by external authentication system to store each user’s email address. This is a required field for environmental authentication. Leave it blank if you are not going to use this feature.

auth_env_realname

Environment variable used by external authentication system to store the user’s real name. Leave it blank if there isn’t one or if this method of authentication is not being used.

user_info_class

Mechanism(s) to be used for gathering a user’s login information. More than one may be selected. If the first one returns nothing, the second is tried, and so on. The types are:

  • CGI: asks for username and password via CGI form interface.

  • Env: info for a pre-authenticated user is passed in system environment variables.

user_verify_class

Mechanism(s) to be used for verifying (authenticating) information gathered by user_info_class. More than one may be selected. If the first one cannot find the user, the second is tried, and so on. The types are:

  • DB: Bugzilla’s built-in authentication. This is the most common choice.

  • RADIUS: RADIUS authentication using a RADIUS server. Using this method requires additional parameters to be set. Please see RADIUS for more information.

  • LDAP: LDAP authentication using an LDAP server. Using this method requires additional parameters to be set. Please see LDAP for more information.

rememberlogin

Controls management of session cookies.

  • on - Session cookies never expire (the user has to login only once per browser).

  • off - Session cookies last until the users session ends (the user will have to login in each new browser session).

  • defaulton/defaultoff - Default behavior as described above, but user can choose whether Bugzilla will remember their login or not.

requirelogin

If this option is set, all access to the system beyond the front page will require a login. No anonymous users will be permitted.

webservice_email_filter

Filter email addresses returned by the WebService API depending on if the user is logged in or not. This works similarly to how the web UI currently filters email addresses. If requirelogin is enabled, then this parameter has no effect as users must be logged in to use Bugzilla anyway.

emailregexp

Defines the regular expression used to validate email addresses used for login names. The default attempts to match fully qualified email addresses (i.e. ‘user@example.com’) in a slightly more restrictive way than what is allowed in RFC 2822. Another popular value to put here is ^[^@]+, which means ‘local usernames, no @ allowed.’

emailregexpdesc

This description is shown to the user to explain which email addresses are allowed by the emailregexp param.

emailsuffix

This is a string to append to any email addresses when actually sending mail to that address. It is useful if you have changed the emailregexp param to only allow local usernames, but you want the mail to be delivered to username@my.local.hostname.

createemailregexp

This defines the (case-insensitive) regexp to use for email addresses that are permitted to self-register. The default (.*) permits any account matching the emailregexp to be created. If this parameter is left blank, no users will be permitted to create their own accounts and all accounts will have to be created by an administrator.

password_complexity

Set the complexity required for passwords. In all cases must the passwords be at least 6 characters long.

  • no_constraints - No complexity required.

  • mixed_letters - Passwords must contain at least one UPPER and one lower case letter.

  • letters_numbers - Passwords must contain at least one UPPER and one lower case letter and a number.

  • letters_numbers_specialchars - Passwords must contain at least one letter, a number and a special character.

password_check_on_login

If set, Bugzilla will check that the password meets the current complexity rules and minimum length requirements when the user logs into the Bugzilla web interface. If it doesn’t, the user would not be able to log in, and will receive a message to reset their password.

4.1.5. Attachments

This page allows for setting restrictions and other parameters regarding attachments to bugs. For example, control size limitations and whether to allow pointing to external files via a URI.

allow_attachment_display

If this option is on, users will be able to view attachments from their browser, if their browser supports the attachment’s MIME type. If this option is off, users are forced to download attachments, even if the browser is able to display them.

If you do not trust your users (e.g. if your Bugzilla is public), you should either leave this option off, or configure and set the attachment_base parameter (see below). Untrusted users may upload attachments that could be potentially damaging if viewed directly in the browser.

attachment_base

When the allow_attachment_display parameter is on, it is possible for a malicious attachment to steal your cookies or perform an attack on Bugzilla using your credentials.

If you would like additional security on attachments to avoid this, set this parameter to an alternate URL for your Bugzilla that is not the same as urlbase or sslbase. That is, a different domain name that resolves to this exact same Bugzilla installation.

Note that if you have set the cookiedomain parameter, you should set attachment_base to use a domain that would not be matched by cookiedomain.

For added security, you can insert %bugid% into the URL, which will be replaced with the ID of the current bug that the attachment is on, when you access an attachment. This will limit attachments to accessing only other attachments on the same bug. Remember, though, that all those possible domain names (such as 1234.your.domain.com) must point to this same Bugzilla instance. To set this up you need to investigate wildcard DNS.

allow_attachment_deletion

If this option is on, administrators will be able to delete the contents of attachments (i.e. replace the attached file with a 0 byte file), leaving only the metadata.

maxattachmentsize

The maximum size (in kilobytes) of attachments to be stored in the database. If a file larger than this size is attached to a bug, Bugzilla will look at the maxlocalattachment parameter to determine if the file can be stored locally on the web server. If the file size exceeds both limits, then the attachment is rejected. Setting both parameters to 0 will prevent attaching files to bugs.

Some databases have default limits which prevent storing larger attachments in the database. E.g. MySQL has a parameter called max_allowed_packet, whose default varies by distribution. Setting maxattachmentsize higher than your current setting for this value will produce an error.

maxlocalattachment

The maximum size (in megabytes) of attachments to be stored locally on the web server. If set to a value lower than the maxattachmentsize parameter, attachments will never be kept on the local filesystem.

Whether you use this feature or not depends on your environment. Reasons to store some or all attachments as files might include poor database performance for large binary blobs, ease of backup/restore/browsing, or even filesystem-level deduplication support. However, you need to be aware of any limits on how much data your webserver environment can store. If in doubt, leave the value at 0.

Note that changing this value does not affect any already-submitted attachments.

4.1.6. Bug Change Policies

Set policy on default behavior for bug change events. For example, choose which status to set a bug to when it is marked as a duplicate, and choose whether to allow bug reporters to set the priority or target milestone. Also allows for configuration of what changes should require the user to make a comment, described below.

duplicate_or_move_bug_status

When a bug is marked as a duplicate of another one, use this bug status.

letsubmitterchoosepriority

If this is on, then people submitting bugs can choose an initial priority for that bug. If off, then all bugs initially have the default priority selected here.

letsubmitterchoosemilestone

If this is on, then people submitting bugs can choose the Target Milestone for that bug. If off, then all bugs initially have the default milestone for the product being filed in.

musthavemilestoneonaccept

If you are using Target Milestone, do you want to require that the milestone be set in order for a user to set a bug’s status to IN_PROGRESS?

commenton*

All these fields allow you to dictate what changes can pass without comment and which must have a comment from the person who changed them. Often, administrators will allow users to add themselves to the CC list, accept bugs, or change the Status Whiteboard without adding a comment as to their reasons for the change, yet require that most other changes come with an explanation. Set the “commenton” options according to your site policy. It is a wise idea to require comments when users resolve, reassign, or reopen bugs at the very least.

Note

It is generally far better to require a developer comment when resolving bugs than not. Few things are more annoying to bug database users than having a developer mark a bug “fixed” without any comment as to what the fix was (or even that it was truly fixed!)

noresolveonopenblockers

This option will prevent users from resolving bugs as FIXED if they have unresolved dependencies. Only the FIXED resolution is affected. Users will be still able to resolve bugs to resolutions other than FIXED if they have unresolved dependent bugs.

4.1.7. Bug Fields

The parameters in this section determine the default settings of several Bugzilla fields for new bugs and whether certain fields are used. For example, choose whether to use the Target Milestone field or the Status Whiteboard field.

useclassification

If this is on, Bugzilla will associate each product with a specific classification. But you must have editclassification permissions enabled in order to edit classifications.

usetargetmilestone

Do you wish to use the Target Milestone field?

useqacontact

This allows you to define an email address for each component, in addition to that of the default assignee, that will be sent carbon copies of incoming bugs.

usestatuswhiteboard

This defines whether you wish to have a free-form, overwritable field associated with each bug. The advantage of the Status Whiteboard is that it can be deleted or modified with ease and provides an easily searchable field for indexing bugs that have some trait in common.

use_see_also

Do you wish to use the See Also field? It allows you mark bugs in other bug tracker installations as being related. Disabling this field prevents addition of new relationships, but existing ones will continue to appear.

defaultpriority

This is the priority that newly entered bugs are set to.

defaultseverity

This is the severity that newly entered bugs are set to.

defaultplatform

This is the platform that is preselected on the bug entry form. You can leave this empty; Bugzilla will then use the platform that the browser is running on as the default.

defaultopsys

This is the operating system that is preselected on the bug entry form. You can leave this empty; Bugzilla will then use the operating system that the browser reports to be running on as the default.

collapsed_comment_tags

A comma-separated list of tags which, when applied to comments, will cause them to be collapsed by default.

4.1.8. Graphs

Bugzilla can draw graphs of bug-dependency relationships, using a tool called dot (from the GraphViz project) or a web service called Web Dot. This page allows you to set the location of the binary or service. If no Web Dot server or binary is specified, then dependency graphs will be disabled.

webdotbase

You may set this parameter to any of the following:

  • A complete file path to dot (part of GraphViz), which will generate the graphs locally.

  • A URL prefix pointing to an installation of the Web Dot package, which will generate the graphs remotely.

  • A blank value, which will disable dependency graphing.

The default value is blank. We recommend using a local install of dot. If you change this value to a web service, make certain that the Web Dot server can read files from your Web Dot directory. On Apache you do this by editing the .htaccess file; for other systems the needed measures may vary. You can run checksetup.pl to recreate the .htaccess file if it has been lost.

font_file

You can specify the full path to a TrueType font file which will be used to display text (labels, legends, …) in charts and graphical reports. To support as many languages as possible, we recommend to specify a TrueType font such as Unifont which supports all printable characters in the Basic Multilingual Plane. If you leave this parameter empty, a default font will be used, but its support is limited to English characters only and so other characters will be displayed incorrectly.

4.1.9. Group Security

Bugzilla allows for the creation of different groups, with the ability to restrict the visibility of bugs in a group to a set of specific users. Specific products can also be associated with groups, and users restricted to only see products in their groups. Several parameters are described in more detail below. Most of the configuration of groups and their relationship to products is done on the Groups and Product pages of the Administration area. The options on this page control global default behavior. For more information on Groups and Group Security, see Groups and Security.

makeproductgroups

Determines whether or not to automatically create groups when new products are created. If this is on, the groups will be used for querying bugs.

chartgroup

The name of the group of users who can use the ‘New Charts’ feature. Administrators should ensure that the public categories and series definitions do not divulge confidential information before enabling this for an untrusted population. If left blank, no users will be able to use New Charts.

insidergroup

The name of the group of users who can see/change private comments and attachments.

timetrackinggroup

The name of the group of users who can see/change time tracking information.

querysharegroup

The name of the group of users who are allowed to share saved searches with one another. For more information on using saved searches, see Saved Searches.

comment_taggers_group

The name of the group of users who can tag comments. Setting this to empty disables comment tagging.

debug_group

The name of the group of users who can view the actual SQL query generated when viewing bug lists and reports. Do not expose this information to untrusted users.

usevisibilitygroups

If selected, user visibility will be restricted to members of groups, as selected in the group configuration settings. Each user-defined group can be allowed to see members of selected other groups. For details on configuring groups (including the visibility restrictions) see Editing Groups and Assigning Group Permissions.

or_groups

Define the visibility of a bug which is in multiple groups. If this is on (recommended), a user only needs to be a member of one of the bug’s groups in order to view it. If it is off, a user needs to be a member of all the bug’s groups. Note that in either case, a user’s role on the bug (e.g. reporter), if any, may also affect their permissions.

4.1.10. LDAP

LDAP authentication is a module for Bugzilla’s plugin authentication architecture. This page contains all the parameters necessary to configure Bugzilla for use with LDAP authentication.

The existing authentication scheme for Bugzilla uses email addresses as the primary user ID and a password to authenticate that user. All places within Bugzilla that require a user ID (e.g assigning a bug) use the email address. The LDAP authentication builds on top of this scheme, rather than replacing it. The initial log-in is done with a username and password for the LDAP directory. Bugzilla tries to bind to LDAP using those credentials and, if successful, tries to map this account to a Bugzilla account. If an LDAP mail attribute is defined, the value of this attribute is used; otherwise, the emailsuffix parameter is appended to the LDAP username to form a full email address. If an account for this address already exists in the Bugzilla installation, it will log in to that account. If no account for that email address exists, one is created at the time of login. (In this case, Bugzilla will attempt to use the “displayName” or “cn” attribute to determine the user’s full name.) After authentication, all other user-related tasks are still handled by email address, not LDAP username. For example, bugs are still assigned by email address and users are still queried by email address.

Warning

Because the Bugzilla account is not created until the first time a user logs in, a user who has not yet logged is unknown to Bugzilla. This means they cannot be used as an assignee or QA contact (default or otherwise), added to any CC list, or any other such operation. One possible workaround is the bugzilla_ldapsync.rb script in the contrib directory. Another possible solution is fixing bug 201069.

Parameters required to use LDAP Authentication:

user_verify_class (in the Authentication section)

If you want to list LDAP here, make sure to have set up the other parameters listed below. Unless you have other (working) authentication methods listed as well, you may otherwise not be able to log back in to Bugzilla once you log out. If this happens to you, you will need to manually edit data/params.json and set user_verify_class to DB.

LDAPserver

This parameter should be set to the name (and optionally the port) of your LDAP server. If no port is specified, it assumes the default LDAP port of 389. For example: ldap.company.com or ldap.company.com:3268 You can also specify a LDAP URI, so as to use other protocols, such as LDAPS or LDAPI. If the port was not specified in the URI, the default is either 389 or 636 for ‘LDAP’ and ‘LDAPS’ schemes respectively.

Note

In order to use SSL with LDAP, specify a URI with “ldaps://”. This will force the use of SSL over port 636. For example, normal LDAP ldap://ldap.company.com, LDAP over SSL ldaps://ldap.company.com, or LDAP over a UNIX domain socket ldapi://%2fvar%2flib%2fldap_sock.

LDAPstarttls

Whether to require encrypted communication once a normal LDAP connection is achieved with the server.

LDAPbinddn [Optional]

Some LDAP servers will not allow an anonymous bind to search the directory. If this is the case with your configuration you should set the LDAPbinddn parameter to the user account Bugzilla should use instead of the anonymous bind. Ex. cn=default,cn=user:password

LDAPBaseDN

The location in your LDAP tree that you would like to search for email addresses. Your uids should be unique under the DN specified here. Ex. ou=People,o=Company

LDAPuidattribute

The attribute which contains the unique UID of your users. The value retrieved from this attribute will be used when attempting to bind as the user to confirm their password. Ex. uid

LDAPmailattribute

The name of the attribute which contains the email address your users will enter into the Bugzilla login boxes. Ex. mail

LDAPfilter

LDAP filter to AND with the LDAPuidattribute for filtering the list of valid users.

4.1.11. RADIUS

RADIUS authentication is a module for Bugzilla’s plugin authentication architecture. This page contains all the parameters necessary for configuring Bugzilla to use RADIUS authentication.

Note

Most caveats that apply to LDAP authentication apply to RADIUS authentication as well. See LDAP for details.

Parameters required to use RADIUS Authentication:

user_verify_class (in the Authentication section)

If you want to list RADIUS here, make sure to have set up the other parameters listed below. Unless you have other (working) authentication methods listed as well, you may otherwise not be able to log back in to Bugzilla once you log out. If this happens to you, you will need to manually edit data/params.json and set user_verify_class to DB.

RADIUS_server

The name (and optionally the port) of your RADIUS server.

RADIUS_secret

The RADIUS server’s secret.

RADIUS_NAS_IP

The NAS-IP-Address attribute to be used when exchanging data with your RADIUS server. If unspecified, 127.0.0.1 will be used.

RADIUS_email_suffix

Bugzilla needs an email address for each user account. Therefore, it needs to determine the email address corresponding to a RADIUS user. Bugzilla offers only a simple way to do this: it can concatenate a suffix to the RADIUS user name to convert it into an email address. You can specify this suffix in the RADIUS_email_suffix parameter. If this simple solution does not work for you, you’ll probably need to modify Bugzilla/Auth/Verify/RADIUS.pm to match your requirements.

4.1.12. Email

This page contains all of the parameters for configuring how Bugzilla deals with the email notifications it sends. See below for a summary of important options.

mail_delivery_method

This is used to specify how email is sent, or if it is sent at all. There are several options included for different MTAs, along with two additional options that disable email sending. Test does not send mail, but instead saves it in data/mailer.testfile for later review. None disables email sending entirely.

mailfrom

This is the email address that will appear in the “From” field of all emails sent by this Bugzilla installation. Some email servers require mail to be from a valid email address; therefore, it is recommended to choose a valid email address here.

use_mailer_queue

In a large Bugzilla installation, updating bugs can be very slow because Bugzilla sends all email at once. If you enable this parameter, Bugzilla will queue all mail and then send it in the background. This requires that you have installed certain Perl modules (as listed by checksetup.pl for this feature), and that you are running the jobqueue.pl daemon (otherwise your mail won’t get sent). This affects all mail sent by Bugzilla, not just bug updates.

smtpserver

The SMTP server address, if the mail_delivery_method parameter is set to SMTP. Use localhost if you have a local MTA running; otherwise, use a remote SMTP server. Append “:” and the port number if a non-default port is needed.

smtp_username

Username to use for SASL authentication to the SMTP server. Leave this parameter empty if your server does not require authentication.

smtp_password

Password to use for SASL authentication to the SMTP server. This parameter will be ignored if the smtp_username parameter is left empty.

smtp_ssl

Enable SSL support for connection to the SMTP server.

smtp_debug

This parameter allows you to enable detailed debugging output. Log messages are printed the web server’s error log.

whinedays

Set this to the number of days you want to let bugs go in the CONFIRMED state before notifying people they have untouched new bugs. If you do not plan to use this feature, simply do not set up the whining cron job described in the installation instructions, or set this value to “0” (never whine).

globalwatchers

This allows you to define specific users who will receive notification each time any new bug in entered, or when any existing bug changes, subject to the normal groupset permissions. It may be useful for sending notifications to a mailing list, for instance.

4.1.13. Query Defaults

This page controls the default behavior of Bugzilla in regards to several aspects of querying bugs. Options include what the default query options are, what the “My Bugs” page returns, whether users can freely add bugs to the quip list, and how many duplicate bugs are needed to add a bug to the “most frequently reported” list.

quip_list_entry_control

Controls how easily users can add entries to the quip list.

  • open - Users may freely add to the quip list, and their entries will immediately be available for viewing.

  • moderated - Quips can be entered but need to be approved by a moderator before they will be shown.

  • closed - No new additions to the quips list are allowed.

mybugstemplate

This is the URL to use to bring up a simple ‘all of my bugs’ list for a user. %userid% will get replaced with the login name of a user. Special characters must be URL encoded.

defaultquery

This is the default query that initially comes up when you access the advanced query page. It’s in URL-parameter format.

search_allow_no_criteria

When turned off, a query must have some criteria specified to limit the number of bugs returned to the user. When turned on, a user is allowed to run a query with no criteria and get all bugs in the entire installation that they can see. Turning this parameter on is not recommended on large installations.

default_search_limit

By default, Bugzilla limits searches done in the web interface to returning only this many results, for performance reasons. (This only affects the HTML format of search results—CSV, XML, and other formats are exempted.) Users can click a link on the search result page to see all the results.

Usually you should not have to change this—the default value should be acceptable for most installations.

max_search_results

The maximum number of bugs that a search can ever return. Tabular and graphical reports are exempted from this limit, however.

4.1.14. Shadow Database

This page controls whether a shadow database is used. If your Bugzilla is not large, you will not need these options.

A standard large database setup involves a single master server and a pool of read-only slaves (which Bugzilla calls the “shadowdb”). Queries which are not updating data can be directed to the slave pool, removing the load/locking from the master, freeing it up to handle writes. Bugzilla will switch to the shadowdb when it knows it doesn’t need to update the database (e.g. when searching, or displaying a bug to a not-logged-in user).

Bugzilla does not make sure the shadowdb is kept up to date, so, if you use one, you will need to set up replication in your database server.

If your shadowdb is on a different machine, specify shadowdbhost and shadowdbport. If it’s on the same machine, specify shadowdbsock.

shadowdbhost

The host the shadow database is on.

shadowdbport

The port the shadow database is on.

shadowdbsock

The socket used to connect to the shadow database, if the host is the local machine.

shadowdb

The database name of the shadow database.

4.1.15. Memcached

memcached_servers

If this option is set, Bugzilla will integrate with Memcached. Specify one or more servers, separated by spaces, using hostname:port notation (for example: 127.0.0.1:11211).

memcached_namespace

Specify a string to prefix each key on Memcached.

4.1.16. User Matching

The settings on this page control how users are selected and queried when adding a user to a bug. For example, users need to be selected when assigning the bug, adding to the CC list, or selecting a QA contact. With the usemenuforusers parameter, it is possible to configure Bugzilla to display a list of users in the fields instead of an empty text field. If users are selected via a text box, this page also contains parameters for how user names can be queried and matched when entered.

usemenuforusers

If this option is set, Bugzilla will offer you a list to select from (instead of a text entry field) where a user needs to be selected. This option should not be enabled on sites where there are a large number of users.

ajax_user_autocompletion

If this option is set, typing characters in a certain user fields will display a list of matches that can be selected from. It is recommended to only turn this on if you are using mod_perl; otherwise, the response will be irritatingly slow.

maxusermatches

Provide no more than this many matches when a user is searched for. If set to ‘1’, no users will be displayed on ambiguous matches. This is useful for user-privacy purposes. A value of zero means no limit.

confirmuniqueusermatch

Whether a confirmation screen should be displayed when only one user matches a search entry.

4.1.17. Advanced

cookiedomain

Defines the domain for Bugzilla cookies. This is typically left blank. If there are multiple hostnames that point to the same webserver, which require the same cookie, then this parameter can be utilized. For example, If your website is at https://bugzilla.example.com/, setting this to .example.com/ will also allow attachments.example.com/ to access Bugzilla cookies.

inbound_proxies

When inbound traffic to Bugzilla goes through a proxy, Bugzilla thinks that the IP address of the proxy is the IP address of every single user. If you enter a comma-separated list of IPs in this parameter, then Bugzilla will trust any X-Forwarded-For header sent from those IPs, and use the value of that header as the end user’s IP address.

proxy_url

If this Bugzilla installation is behind a proxy, enter the proxy information here to enable Bugzilla to access the Internet. Bugzilla requires Internet access to utilize the upgrade_notification parameter. If the proxy requires authentication, use the syntax: http://user:pass@proxy_url/.

strict_transport_security

Enables the sending of the Strict-Transport-Security header along with HTTP responses on SSL connections. This adds greater security to your SSL connections by forcing the browser to always access your domain over SSL and never accept an invalid certificate. However, it should only be used if you have the ssl_redirect parameter turned on, Bugzilla is the only thing running on its domain (i.e., your urlbase is something like http://bugzilla.example.com/), and you never plan to stop supporting SSL.

  • off - Don’t send the Strict-Transport-Security header with requests.

  • this_domain_only - Send the Strict-Transport-Security header with all requests, but only support it for the current domain.

  • include_subdomains - Send the Strict-Transport-Security header along with the includeSubDomains flag, which will apply the security change to all subdomains. This is especially useful when combined with an attachment_base that exists as (a) subdomain(s) under the main Bugzilla domain.
