    4 Trac uses a simple but flexible permission system to control what users can and can't access.
     4Trac uses a simple, case sensitive, permission system to control what users can and can't access.

    6 Permission privileges are managed using the [wiki:TracAdmin trac-admin] tool.
     6Permission privileges are managed using the [TracAdmin trac-admin] tool or the ''General / Permissions'' panel in the ''Admin'' web interface.
    77
    8 Regular visitors, non-authenticated users, accessing the system are assigned the default
    9 role (''user'') named {{{anonymous}}}.
    10 Assign permissions to the {{{anonymous}}} user to set privileges for non-authenticated/guest users.
     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.
    119
    12 In addition to these privileges users can be granted additional individual
    13 rights in effect when authenticated and logged into the system.
     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".
    1412
    1513== Available Privileges ==
    1614
    17 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 let you do anything you want.
     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.

    19 Otherwise, individual privileges can be assigned to users for the various different functional areas of Trac:

    7078== Granting Privileges ==
    7179
    72 Currently the only way to grant privileges to users is by using the `trac-admin` script. The current set of privileges can be listed with the following command:
     80You grant privileges to users using [wiki:TracAdmin trac-admin]. The current set of privileges can be listed with the following command:
    7381{{{
    7482  $ trac-admin /path/to/projenv permission list
     
    8088}}}
    8189
     90The `permission add` command also accepts multiple privilege names:
     91{{{
     92  $ trac-admin /path/to/projenv permission add bob REPORT_DELETE WIKI_CREATE
     93}}}
     94
     95Or add all privileges:
     96{{{
     97  $ trac-admin /path/to/projenv permission add bob TRAC_ADMIN
     98}}}
     99
    82100== Permission Groups ==
     101
     102There are two built-in groups, "authenticated" and "anonymous".[[BR]]
     103Any user who has not logged in is automatically in the "anonymous" group.[[BR]]
     104Any user who has logged in is also in the "authenticated" group.[[BR]]
     105The "authenticated" group inherits permissions from the "anonymous" group.[[BR]]
     106eg. if the "anonymous" group has permission WIKI_MODIFY, it's not necessary to add the WIKI_MODIFY permisison to the "authenticated" group as well.
     107
     108Custom groups may be defined that inherit permissions from the two built-in groups.
    83109
    84110Permissions can be grouped together to form roles such as ''developer'', ''admin'', etc.
     
    91117}}}
    92118
     119Group 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'''.
     120
     121== Adding a New Group and Permissions ==
     122Permission groups can be created by assigning a user to a group you wish to create, then assign permissions to that group.
     123
     124The 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)
     125{{{
     126   $ trac-admin /path/to/projenv permission add bob beta_testers
     127   $ trac-admin /path/to/projenv permission add beta_testers WIKI_ADMIN
     128
     129}}}
     130
     131== Removing Permissions ==
     132
     133Permissions can be removed using the 'remove' command. For example:
     134
     135This command will prevent the user ''bob'' from deleting reports:
     136{{{
     137  $ trac-admin /path/to/projenv permission remove bob REPORT_DELETE
     138}}}
     139
     140Just like `permission add`, this command accepts multiple privilege names.
     141
     142You can also remove all privileges for a specific user:
     143{{{
     144  $ trac-admin /path/to/projenv permission remove bob '*'
     145}}}
     146
     147Or one privilege for all users:
     148{{{
     149  $ trac-admin /path/to/projenv permission remove '*' REPORT_ADMIN
     150}}}
     151
    93152== Default Permissions ==
    94153
    95 Granting privileges to the special user ''anonymous'' can be used to control what an anonymous user can do before they have logged in.
     154By 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.
     155On the other hand, the `authenticated` users will have the permissions to ''create and modify tickets and wiki pages''.
    96156
    97 In the same way, privileges granted to the special user ''authenticated'' will apply to any authenticated (logged in) user.
