  • TracPermissions

    v4 v5  
    44Trac uses a simple, case sensitive, permission system to control what users can and can't access.
    55
    6 Permission privileges are managed using the [TracAdmin trac-admin] tool or the ''General / Permissions'' panel in the ''Admin'' tab of the web interface.
    7 
    8 In addition to the default permission policy described in this page, it is possible to activate additional permission policies by enabling plugins and listing them in the `[trac] permission_policies` configuration entry in the TracIni. See TracFineGrainedPermissions for more details.
    9 
    10 Non-authenticated users accessing the system are assigned the name "anonymous". Assign permissions to the "anonymous" user to set privileges for anonymous/guest users. The parts of Trac that a user does not have the privileges for will not be displayed in the navigation.
    11 In addition to these privileges, users can be granted additional individual rights in effect when authenticated and logged into the system. All logged in users belong to the virtual group "authenticated", which inherits permissions from "anonymous".
     6Permissions are managed using the [TracAdmin trac-admin] tool or the ''General / Permissions'' panel in the ''Admin'' tab of the web interface.
     7
     8In addition to the default permission policy described in this page, it is possible to activate additional permission policies by enabling plugins and listing them in [TracIni#trac-permission_policies-option "[trac] permission_policies"]. See TracFineGrainedPermissions for more details.
     9
     10Non-authenticated users accessing the system are assigned the name //anonymous//. Assign permissions to the //anonymous// user to set privileges for anonymous/guest users. The parts of Trac that a user does not have privilege for will not be displayed in the navigation.
     11In addition to these privileges, users can be granted additional individual rights in effect when authenticated and logged into the system. All logged in users belong to the virtual group //authenticated//, which inherits permissions from //anonymous//.

    1313== Graphical Admin Tab
    1414
    1515To access this tab, a user must have one of the following permissions: `TRAC_ADMIN`, `PERMISSION_ADMIN`, `PERMISSION_GRANT`, `PERMISSION_REVOKE`. The permissions can be granted using the `trac-admin` command (more on `trac-admin` below):
    16 {{{
    17   $ trac-admin /path/to/projenv permission add bob TRAC_ADMIN
    18 }}}
    19 
    20 Then, the user `bob` will be able to see the Admin tab, and can then access the permissions menu. This menu will allow you to perform all the following actions, but from the browser without requiring root access to the server (just the correct permissions for your user account). '''Use at least one lowercase character in user names, as all-uppercase names are reserved for permissions.'''

    23  1. [[Image(htdocs:../common/guide/admin-permissions.png)]]
    24  1. [[Image(htdocs:../common/guide/admin-permissions-TICKET_ADMIN.png)]]
    25 
    26 An easy way to quickly secure a new Trac install is to run the above command on the anonymous user, install the [http://trac-hacks.org/wiki/AccountManagerPlugin AccountManagerPlugin], create a new admin account graphically and then remove the TRAC_ADMIN permission from the anonymous user.
     16{{{#!sh
     17$ trac-admin /path/to/projenv permission add bob TRAC_ADMIN
     18}}}
     19
     20Then, the user `bob` will be able to see the Admin tab, and can access the permissions menu. This menu will allow you to perform all the following actions, but from the browser rather than requiring root access to the server. '''Use at least one lowercase character in user names, as all-uppercase names are reserved for permissions.'''

     26[[Image(htdocs:../common/guide/admin-permissions-TICKET_ADMIN.png)]]
    2727
    2828From the graphical admin tab, users with `PERMISSION_GRANT` will only be allowed to grant permissions that they possess, and users with `PERMISSION_REVOKE` will only be allowed to revoke permissions that they possess. For example, a user cannot grant `MILESTONE_ADMIN` unless they have `PERMISSION_GRANT` and `MILESTONE_ADMIN`, and they cannot revoke `MILESTONE_ADMIN` unless they have `PERMISSION_REVOKE` and `MILESTONE_ADMIN`. `PERMISSION_ADMIN` just grants the user both `PERMISSION_GRANT` and `PERMISSION_REVOKE`, and users with `TRAC_ADMIN` can grant or revoke any permission.

    97 || `EMAIL_VIEW` || Shows email addresses even if [wiki:TracIni#trac-section trac show_email_addresses] configuration option is false ||
    98 
    99 == Creating New Privileges
    100 
    101 To create custom permissions, for example to be used in a custom workflow, enable the optional [trac:ExtraPermissionsProvider tracopt.perm.config_perm_provider.ExtraPermissionsProvider] component in the "Plugins" admin panel, and add the desired permissions to the `[extra-permissions]` section in your [wiki:TracIni#extra-permissions-section trac.ini]. For more information, please refer to the documentation  on the [wiki:TracIni#extra-permissions-section TracIni] page after enabling the component.
     92|| `TIMELINE_VIEW` || View the [TracTimeline timeline] page ||
     93|| `SEARCH_VIEW` || View and execute [TracSearch search] queries ||
     94|| `CONFIG_VIEW` || Enables additional sections on ''About Trac'' that show the current configuration and the list of installed plugins ||
     95|| `EMAIL_VIEW` || Shows email addresses even if [TracIni#trac-section trac show_email_addresses] configuration option is false ||
     96
     97== Attachment Permissions
     98
     99Attachment permissions are handled by `LegacyAttachmentPolicy`, and unlike the permissions discussed so far, the permissions provided by `LegacyAttachmentPolicy` are not directly granted. Rather, the ability to create, view and delete attachments is determined by the attachment's parent realm and permissions the user possesses for that realm.
     100
     101The attachment actions are determined by the following
     102permissions in the ticket, wiki and milestone realms:
     103{{{#!table class="listing"
     104||= Granted By: =||= Ticket =||= Wiki =||= Milestone =||
     105|| `ATTACHMENT_CREATE` || `TICKET_APPEND` || `WIKI_MODIFY` || `MILESTONE_MODIFY` ||
     106|| `ATTACHMENT_VIEW` || `TICKET_VIEW` || `WIKI_VIEW` || `MILESTONE_VIEW` ||
     107|| `ATTACHMENT_DELETE` || `TICKET_ADMIN` || `WIKI_DELETE` || `MILESTONE_DELETE` ||
     108}}}
     109
     110If explicit attachment permissions are preferred, `ATTACHMENT_CREATE`, `ATTACHMENT_DELETE` and `ATTACHMENT_VIEW` can be created using the [trac:ExtraPermissionsProvider]. The simplest implementation is to simply define the actions.
     111{{{#!ini
     112[extra-permissions]
     113_perms = ATTACHMENT_CREATE, ATTACHMENT_DELETE, ATTACHMENT_VIEW
     114}}}
     115
     116An alternative configuration adds an `ATTACHMENT_ADMIN` meta-permission that grants the other 3 permission.
     117{{{#!ini
     118[extra-permissions]
     119ATTACHMENT_ADMIN = ATTACHMENT_CREATE, ATTACHMENT_DELETE, ATTACHMENT_VIEW
     120}}}
     121
     122The explicit permissions can be used in concert with `LegacyAttachmentPolicy`, or `LegacyAttachmentPolicy` can be removed from `permission_policies`, in which case only users that have been explicitly granted the corresponding attachment actions will be able to create, delete and view attachments.
    102123
    103124== Granting Privileges
    104125
    105 You grant privileges to users using [wiki:TracAdmin trac-admin]. The current set of privileges can be listed with the following command:
    106 {{{
    107   $ trac-admin /path/to/projenv permission list
     126You grant privileges to users using [TracAdmin trac-admin]. The current set of privileges can be listed with the following command:
     127{{{#!sh
     128$ trac-admin /path/to/projenv permission list
    108129}}}
    109130
    110131This command will allow the user ''bob'' to delete reports:
    111 {{{
    112   $ trac-admin /path/to/projenv permission add bob REPORT_DELETE
     132{{{#!sh
     133$ trac-admin /path/to/projenv permission add bob REPORT_DELETE
    113134}}}
    114135
    115136The `permission add` command also accepts multiple privilege names:
    116 {{{
    117   $ trac-admin /path/to/projenv permission add bob REPORT_DELETE WIKI_CREATE
     137{{{#!sh
     138$ trac-admin /path/to/projenv permission add bob REPORT_DELETE WIKI_CREATE
    118139}}}
    119140
    120141Or add all privileges:
    121 {{{
    122   $ trac-admin /path/to/projenv permission add bob TRAC_ADMIN
     142{{{#!sh
     143$ trac-admin /path/to/projenv permission add bob TRAC_ADMIN
    123144}}}
    124145
    125146== Permission Groups
    126147
    127 There are two built-in groups, "authenticated" and "anonymous".
    128 Any user who has not logged in is automatically in the "anonymous" group.
    129 Any user who has logged in is also in the "authenticated" group.
    130 The "authenticated" group inherits permissions from the "anonymous" group.
    131 For example, if the "anonymous" group has permission WIKI_MODIFY,
    132 it is not necessary to add the WIKI_MODIFY permission to the "authenticated" group as well.
     148There are two built-in groups, //authenticated// and //anonymous//.
     149Any user who has not logged in is automatically in the //anonymous// group.
     150Any user who has logged in is also in the //authenticated// group.
     151The //authenticated// group inherits permissions from the //anonymous// group.
     152For example, if the //anonymous// group has permission WIKI_MODIFY,
     153it is not necessary to add the WIKI_MODIFY permission to the //authenticated// group as well.
    133154
    134155Custom groups may be defined that inherit permissions from the two built-in groups.
    135156
    136157Permissions can be grouped together to form roles such as ''developer'', ''admin'', etc.
    137 {{{
    138   $ trac-admin /path/to/projenv permission add developer WIKI_ADMIN
    139   $ trac-admin /path/to/projenv permission add developer REPORT_ADMIN
    140   $ trac-admin /path/to/projenv permission add developer TICKET_MODIFY
    141   $ trac-admin /path/to/projenv permission add bob developer
    142   $ trac-admin /path/to/projenv permission add john developer
     158{{{#!sh
     159$ trac-admin /path/to/projenv permission add developer WIKI_ADMIN
     160$ trac-admin /path/to/projenv permission add developer REPORT_ADMIN
     161$ trac-admin /path/to/projenv permission add developer TICKET_MODIFY
     162$ trac-admin /path/to/projenv permission add bob developer
     163$ trac-admin /path/to/projenv permission add john developer
    143164}}}
    144165
    … …  
    149170
    150171The following will add ''bob'' to the new group called ''beta_testers'' and then will assign WIKI_ADMIN permissions to that group. (Thus, ''bob'' will inherit the WIKI_ADMIN permission)
    151 {{{
    152    $ trac-admin /path/to/projenv permission add bob beta_testers
    153    $ trac-admin /path/to/projenv permission add beta_testers WIKI_ADMIN
    154 
     172{{{#!sh
     173$ trac-admin /path/to/projenv permission add bob beta_testers

    … …  
    160180
    161181This command will prevent the user ''bob'' from deleting reports:
     182{{{#!sh
     183$ trac-admin /path/to/projenv permission remove bob REPORT_DELETE
     184}}}
     185
     186Just like `permission add`, this command accepts multiple privilege names.
     187
     188You can also remove all privileges for a specific user:
     189{{{#!sh
     190$ trac-admin /path/to/projenv permission remove bob '*'
     191}}}
     192
     193Or one privilege for all users:
     194{{{#!sh
     195$ trac-admin /path/to/projenv permission remove '*' REPORT_ADMIN
     196}}}
     197
     198== Creating New Privileges
     199
     200To create custom permissions, for example to be used in a custom workflow, enable the optional [trac:ExtraPermissionsProvider tracopt.perm.config_perm_provider.ExtraPermissionsProvider] component in the "Plugins" admin panel, and add the desired permissions to the `[extra-permissions]` section in your [TracIni#extra-permissions-section trac.ini].

     201
     202== Default Permissions
     203
     204By default on a new Trac installation, the //anonymous// user will have ''view'' access to everything in Trac, but will not be able to create or modify anything.
     205On the other hand, the //authenticated// users will have the permissions to ''create and modify tickets and wiki pages''.
