    44Trac uses a simple, case sensitive, permission system to control what users can and can't access.
    55
    6 Permission 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.

    88In 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.
     
    1111In 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".

    16 To access this tab, a user must have `TRAC_ADMIN privileges`. This can be performed as follows (more on the trac-admin script below):
     13== Graphical Admin Tab

     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 (more on `trac-admin` below):
    1716{{{
    1817  $ trac-admin /path/to/projenv permission add bob TRAC_ADMIN
    1918}}}

    21 Then, 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).

    2726An 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.
    2827
    29 == Available Privileges ==
     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
    3031
    3132To 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.
     
    3334Otherwise, individual privileges can be assigned to users for the various different functional areas of Trac ('''note that the privilege names are case-sensitive'''):

     101To 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.
