     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 the ''General / Permissions'' panel in the ''Admin'' 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== Available Privileges == 
     14 
     15To 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. 
     16 
     17Otherwise, individual privileges can be assigned to users for the various different functional areas of Trac ('''note that the privilege names are case-sensitive'''):

     79 
     80== Granting Privileges == 
     81 
     82You grant privileges to users using [wiki:TracAdmin trac-admin]. The current set of privileges can be listed with the following command: 
     83{{{ 
     84  $ trac-admin /path/to/projenv permission list 
     85}}} 
     86 
     87This command will allow the user ''bob'' to delete reports: 
     88{{{ 
     89  $ trac-admin /path/to/projenv permission add bob REPORT_DELETE 
     90}}} 
     91 
     92The `permission add` command also accepts multiple privilege names: 
     93{{{ 
     94  $ trac-admin /path/to/projenv permission add bob REPORT_DELETE WIKI_CREATE 
     95}}} 
     96 
     97Or add all privileges: 
     98{{{ 
     99  $ trac-admin /path/to/projenv permission add bob TRAC_ADMIN 
     100}}} 
     101 
     102== Permission Groups == 
     103 
     104There are two built-in groups, "authenticated" and "anonymous".[[BR]] 
     105Any user who has not logged in is automatically in the "anonymous" group.[[BR]] 
     106Any user who has logged in is also in the "authenticated" group.[[BR]] 
     107The "authenticated" group inherits permissions from the "anonymous" group.[[BR]] 
     108eg. if the "anonymous" group has permission WIKI_MODIFY, it's not necessary to add the WIKI_MODIFY permisison to the "authenticated" group as well. 
     109 
     110Custom groups may be defined that inherit permissions from the two built-in groups. 
     111 
     112Permissions can be grouped together to form roles such as ''developer'', ''admin'', etc. 
     113{{{ 
     114  $ trac-admin /path/to/projenv permission add developer WIKI_ADMIN 
     115  $ trac-admin /path/to/projenv permission add developer REPORT_ADMIN 
     116  $ trac-admin /path/to/projenv permission add developer TICKET_MODIFY 
     117  $ trac-admin /path/to/projenv permission add bob developer 
     118  $ trac-admin /path/to/projenv permission add john developer 
     119}}} 
     120 
     121Group 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'''. 
     122 
     123== Adding a New Group and Permissions == 
     124Permission groups can be created by assigning a user to a group you wish to create, then assign permissions to that group. 
     125 
     126The 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) 
     127{{{  
     128   $ trac-admin /path/to/projenv permission add bob beta_testers 
     129   $ trac-admin /path/to/projenv permission add beta_testers WIKI_ADMIN 
     130 
     131}}} 
     132 
     133== Removing Permissions == 
     134 
     135Permissions can be removed using the 'remove' command. For example: 
     136 
     137This command will prevent the user ''bob'' from deleting reports: 
     138{{{ 
     139  $ trac-admin /path/to/projenv permission remove bob REPORT_DELETE 
     140}}} 
     141 
     142Just like `permission add`, this command accepts multiple privilege names. 
     143 
     144You can also remove all privileges for a specific user: 
     145{{{ 
     146  $ trac-admin /path/to/projenv permission remove bob '*' 
     147}}} 
     148 
     149Or one privilege for all users: 
     150{{{ 
     151  $ trac-admin /path/to/projenv permission remove '*' REPORT_ADMIN 
     152}}} 
     153 
     154== Default Permissions == 
     155 
     156By 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. 
     157On the other hand, the `authenticated` users will have the permissions to ''create and modify tickets and wiki pages''. 
     158 
     159 '''anonymous''':: 
     160 BROWSER_VIEW  
     161 CHANGESET_VIEW  
     162 FILE_VIEW  
     163 LOG_VIEW  
     164 MILESTONE_VIEW  
     165 REPORT_SQL_VIEW  
     166 REPORT_VIEW  
     167 ROADMAP_VIEW  
     168 SEARCH_VIEW  
     169 TICKET_VIEW  
     170 TIMELINE_VIEW 
     171 WIKI_VIEW  
     172 
     173 '''authenticated''':: 
     174 TICKET_CREATE  
     175 TICKET_MODIFY  
     176 WIKI_CREATE  
     177 WIKI_MODIFY   
     178
