     1= Trac Permissions =
     2[[TracGuideToc]]
     3
     4Trac uses a simple, case sensitive, permission system to control what users can and can't access.
     5
     6Permission privileges are managed using the [TracAdmin trac-admin] tool or (new in version 0.11) 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 the `[trac] permission_policies` configuration entry in the TracIni. 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 the privileges 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".
     12
     13== Graphical Admin Tab ==
     14''This feature is new in version 0.11.''
     15
     16To access this tab, a user must have `TRAC_ADMIN privileges`. This can be performed as follows (more on the trac-admin script below):
     17{{{
     18  $ trac-admin /path/to/projenv permission add bob TRAC_ADMIN
     19}}}
     20
     21Then, the user 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).
     22
     23
     24== Available Privileges ==
     25
     26To enable all privileges for a user, use the `TRAC_ADMIN` permission. Having `TRAC_ADMIN` is like being `root` on a *NIX system: it will allow you to perform any operation.
     27
     28Otherwise, individual privileges can be assigned to users for the various different functional areas of Trac ('''note that the privilege names are case-sensitive'''):

     90
     91== Granting Privileges ==
     92
     93You grant privileges to users using [wiki:TracAdmin trac-admin]. The current set of privileges can be listed with the following command:
     94{{{
     95  $ trac-admin /path/to/projenv permission list
     96}}}
     97
     98This command will allow the user ''bob'' to delete reports:
     99{{{
     100  $ trac-admin /path/to/projenv permission add bob REPORT_DELETE
     101}}}
     102
     103The `permission add` command also accepts multiple privilege names:
     104{{{
     105  $ trac-admin /path/to/projenv permission add bob REPORT_DELETE WIKI_CREATE
     106}}}
     107
     108Or add all privileges:
     109{{{
     110  $ trac-admin /path/to/projenv permission add bob TRAC_ADMIN
     111}}}
     112
     113== Permission Groups ==
     114
     115There are two built-in groups, "authenticated" and "anonymous".[[BR]]
     116Any user who has not logged in is automatically in the "anonymous" group.[[BR]]
     117Any user who has logged in is also in the "authenticated" group.[[BR]]
     118The "authenticated" group inherits permissions from the "anonymous" group.[[BR]]
     119eg. if the "anonymous" group has permission WIKI_MODIFY, it's not necessary to add the WIKI_MODIFY permisison to the "authenticated" group as well.
     120
     121Custom groups may be defined that inherit permissions from the two built-in groups.
     122
     123Permissions can be grouped together to form roles such as ''developer'', ''admin'', etc.
     124{{{
     125  $ trac-admin /path/to/projenv permission add developer WIKI_ADMIN
     126  $ trac-admin /path/to/projenv permission add developer REPORT_ADMIN
     127  $ trac-admin /path/to/projenv permission add developer TICKET_MODIFY
     128  $ trac-admin /path/to/projenv permission add bob developer
     129  $ trac-admin /path/to/projenv permission add john developer
     130}}}
     131
     132Group membership can be checked by doing a {{{permission list}}} with no further arguments; the resulting output will include group memberships. '''Use lowercase for group names, as uppercase is reserved for permissions'''.
     133
     134== Adding a New Group and Permissions ==
     135Permission groups can be created by assigning a user to a group you wish to create, then assign permissions to that group.
     136
     137The 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)
     138{{{
     139   $ trac-admin /path/to/projenv permission add bob beta_testers
     140   $ trac-admin /path/to/projenv permission add beta_testers WIKI_ADMIN
     141
     142}}}
     143
     144== Removing Permissions ==
     145
     146Permissions can be removed using the 'remove' command. For example:
     147
     148This command will prevent the user ''bob'' from deleting reports:
     149{{{
     150  $ trac-admin /path/to/projenv permission remove bob REPORT_DELETE
     151}}}
     152
     153Just like `permission add`, this command accepts multiple privilege names.
     154
     155You can also remove all privileges for a specific user:
     156{{{
     157  $ trac-admin /path/to/projenv permission remove bob '*'
     158}}}
     159
     160Or one privilege for all users:
     161{{{
     162  $ trac-admin /path/to/projenv permission remove '*' REPORT_ADMIN
     163}}}
     164
     165== Default Permissions ==
     166
     167By 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.
     168On the other hand, the `authenticated` users will have the permissions to ''create and modify tickets and wiki pages''.
     169
     170 '''anonymous'''::
     171 BROWSER_VIEW
     172 CHANGESET_VIEW
     173 FILE_VIEW
     174 LOG_VIEW
     175 MILESTONE_VIEW
     176 REPORT_SQL_VIEW
     177 REPORT_VIEW
     178 ROADMAP_VIEW
     179 SEARCH_VIEW

     181 TIMELINE_VIEW
     182 WIKI_VIEW
     183
     184 '''authenticated'''::

     186 TICKET_MODIFY
     187 WIKI_CREATE
     188 WIKI_MODIFY
