    v1 v1  
     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 `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.'''

     26 
     27An 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. 
     28 
     29== Available Privileges == 
     30 
     31To 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. 
     32 
     33Otherwise, individual privileges can be assigned to users for the various different functional areas of Trac ('''note that the privilege names are case-sensitive'''):

     96 
     97== Creating New Privileges == 
     98 
     99To create custom permissions, for example to be used in a custom workflow, enable the optional `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 of the component in the admin panel. 
     100 
     101== Granting Privileges == 
     102 
     103You grant privileges to users using [wiki:TracAdmin trac-admin]. The current set of privileges can be listed with the following command: 
     104{{{ 
     105  $ trac-admin /path/to/projenv permission list 
     106}}} 
     107 
     108This command will allow the user ''bob'' to delete reports: 
     109{{{ 
     110  $ trac-admin /path/to/projenv permission add bob REPORT_DELETE 
     111}}} 
     112 
     113The `permission add` command also accepts multiple privilege names: 
     114{{{ 
     115  $ trac-admin /path/to/projenv permission add bob REPORT_DELETE WIKI_CREATE 
     116}}} 
     117 
     118Or add all privileges: 
     119{{{ 
     120  $ trac-admin /path/to/projenv permission add bob TRAC_ADMIN 
     121}}} 
     122 
     123== Permission Groups == 
     124 
     125There are two built-in groups, "authenticated" and "anonymous". 
     126Any user who has not logged in is automatically in the "anonymous" group. 
     127Any user who has logged in is also in the "authenticated" group. 
     128The "authenticated" group inherits permissions from the "anonymous" group. 
     129For example, if the "anonymous" group has permission WIKI_MODIFY,  
     130it is not necessary to add the WIKI_MODIFY permission to the "authenticated" group as well. 
     131 
     132Custom groups may be defined that inherit permissions from the two built-in groups. 
     133 
     134Permissions can be grouped together to form roles such as ''developer'', ''admin'', etc. 
     135{{{ 
     136  $ trac-admin /path/to/projenv permission add developer WIKI_ADMIN 
     137  $ trac-admin /path/to/projenv permission add developer REPORT_ADMIN 
     138  $ trac-admin /path/to/projenv permission add developer TICKET_MODIFY 
     139  $ trac-admin /path/to/projenv permission add bob developer 
     140  $ trac-admin /path/to/projenv permission add john developer 
     141}}} 
     142 
     143Group membership can be checked by doing a {{{permission list}}} with no further arguments; the resulting output will include group memberships. '''Use at least one lowercase character in group names, as all-uppercase names are reserved for permissions'''. 
     144 
     145== Adding a New Group and Permissions == 
     146Permission groups can be created by assigning a user to a group you wish to create, then assign permissions to that group. 
     147 
     148The 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) 
     149{{{  
     150   $ trac-admin /path/to/projenv permission add bob beta_testers 
     151   $ trac-admin /path/to/projenv permission add beta_testers WIKI_ADMIN 
     152 
     153}}} 
     154 
     155== Removing Permissions == 
     156 
     157Permissions can be removed using the 'remove' command. For example: 
     158 
     159This command will prevent the user ''bob'' from deleting reports: 
     160{{{ 
     161  $ trac-admin /path/to/projenv permission remove bob REPORT_DELETE 
     162}}} 
     163 
     164Just like `permission add`, this command accepts multiple privilege names. 
     165 
     166You can also remove all privileges for a specific user: 
     167{{{ 
     168  $ trac-admin /path/to/projenv permission remove bob '*' 
     169}}} 
     170 
     171Or one privilege for all users: 
     172{{{ 
     173  $ trac-admin /path/to/projenv permission remove '*' REPORT_ADMIN 
     174}}} 
     175 
     176== Default Permissions == 
     177 
     178By 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. 
     179On the other hand, the `authenticated` users will have the permissions to ''create and modify tickets and wiki pages''. 
     180 
     181'''anonymous''' 
     182{{{ 
     183 BROWSER_VIEW  
     184 CHANGESET_VIEW  
     185 FILE_VIEW  
     186 LOG_VIEW  
     187 MILESTONE_VIEW  
     188 REPORT_SQL_VIEW  
     189 REPORT_VIEW  
     190 ROADMAP_VIEW  
     191 SEARCH_VIEW  
     192 TICKET_VIEW  
     193 TIMELINE_VIEW 
     194 WIKI_VIEW 
     195}}} 
     196 
     197'''authenticated''' 
     198{{{ 
     199 TICKET_CREATE  
     200 TICKET_MODIFY  
     201 WIKI_CREATE  
     202 WIKI_MODIFY   
     203}}}
