    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
     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 [TracPlugins 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//.
     12
     13== Graphical Admin Tab
     14
     15To 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 with a more detailed description [#GrantingPrivileges below]:
     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.'''

     25
     26[[Image(htdocs:../common/guide/admin-permissions-TICKET_ADMIN.png)]]
     27
     28From 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.
     29
     30== Available Privileges
     31
     32To enable all privileges for a user, use the `TRAC_ADMIN` permission. This permission is like being `root` on a *NIX system: it will allow you to perform any operation.
     33
     34Otherwise, individual privileges can be assigned to users for the different functional areas of Trac and '''note that the privilege names are uppercase''':

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