    4 Trac uses a simple permission system to control what users can and can't access.
    5 
    6 Permission privileges are managed using the [wiki:TracAdmin trac-admin] tool.
     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.
    79
    810Non-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.
    9 
    1011In 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".

     13== Graphical Admin Tab ==
     14''This feature is new in version 0.11.''
     15
     16To 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):
     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
     29From 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.
     30
    1231== Available Privileges ==
    1332
    14 To 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 perform any operation.
    15 
    16 Otherwise, individual privileges can be assigned to users for the various different functional areas of Trac (note that the privilege names are case-sensitive):

     100== Creating New Privileges ==
     101
     102To 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.

    66104== Granting Privileges ==
     
    81119}}}
    82120
     121Or add all privileges:
     122{{{
     123  $ trac-admin /path/to/projenv permission add bob TRAC_ADMIN
     124}}}
     125
    83126== Permission Groups ==
     127
     128There are two built-in groups, "authenticated" and "anonymous".
     129Any user who has not logged in is automatically in the "anonymous" group.
     130Any user who has logged in is also in the "authenticated" group.
     131The "authenticated" group inherits permissions from the "anonymous" group.
     132For example, if the "anonymous" group has permission WIKI_MODIFY,
     133it is not necessary to add the WIKI_MODIFY permission to the "authenticated" group as well.
     134
     135Custom groups may be defined that inherit permissions from the two built-in groups.
    84136
    85137Permissions can be grouped together to form roles such as ''developer'', ''admin'', etc.
     
    92144}}}
    93145
    94 Group 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.
     146Group 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'''.
     147
     148== Adding a New Group and Permissions ==
     149Permission groups can be created by assigning a user to a group you wish to create, then assign permissions to that group.
     150
     151The 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)
     152{{{
     153   $ trac-admin /path/to/projenv permission add bob beta_testers
     154   $ trac-admin /path/to/projenv permission add beta_testers WIKI_ADMIN
     155
     156}}}
    95157
    96158== Removing Permissions ==
     
    107169You can also remove all privileges for a specific user:
    108170{{{
    109   $ trac-admin /path/to/projenv permission remove bob *
     171  $ trac-admin /path/to/projenv permission remove bob '*'
    110172}}}
    111173
    112174Or one privilege for all users:
    113175{{{
    114   $ trac-admin /path/to/projenv permission remove * REPORT_ADMIN
     176  $ trac-admin /path/to/projenv permission remove '*' REPORT_ADMIN
    115177}}}
    116178
    117179== Default Permissions ==
    118180
    119 Granting privileges to the special user ''anonymous'' can be used to control what an anonymous user can do before they have logged in.
    120 
    121 In the same way, privileges granted to the special user ''authenticated'' will apply to any authenticated (logged in) user.
    122 
     181By 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.
     182On the other hand, the `authenticated` users will have the permissions to ''create and modify tickets and wiki pages''.
