    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".
    1112
     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_ADD`, `PERMISSION_REMOVE`. The permissions can 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.'''

     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
    1229== Available Privileges ==
    1330
    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):

     97== Creating New Privileges ==
     98
     99To 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 of the component in the admin panel.

    66101== Granting Privileges ==
     
    81116}}}
    82117
     118Or add all privileges:
     119{{{
     120  $ trac-admin /path/to/projenv permission add bob TRAC_ADMIN
     121}}}
     122
    83123== Permission Groups ==
     124
     125There are two built-in groups, "authenticated" and "anonymous".
     126Any user who has not logged in is automatically in the "anonymous" group.
     127Any user who has logged in is also in the "authenticated" group.
     128The "authenticated" group inherits permissions from the "anonymous" group.
     129For example, if the "anonymous" group has permission WIKI_MODIFY,
     130it is not necessary to add the WIKI_MODIFY permission to the "authenticated" group as well.
     131
     132Custom groups may be defined that inherit permissions from the two built-in groups.
    84133
    85134Permissions can be grouped together to form roles such as ''developer'', ''admin'', etc.
     
    92141}}}
    93142
    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.
     143Group 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'''.
     144
     145== Adding a New Group and Permissions ==
     146Permission groups can be created by assigning a user to a group you wish to create, then assign permissions to that group.
     147
     148The 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)
     149{{{
     150   $ trac-admin /path/to/projenv permission add bob beta_testers
     151   $ trac-admin /path/to/projenv permission add beta_testers WIKI_ADMIN
     152
     153}}}
    95154
    96155== Removing Permissions ==
     
    107166You can also remove all privileges for a specific user:
    108167{{{
    109   $ trac-admin /path/to/projenv permission remove bob *
     168  $ trac-admin /path/to/projenv permission remove bob '*'
    110169}}}
    111170
    112171Or one privilege for all users:
    113172{{{
    114   $ trac-admin /path/to/projenv permission remove * REPORT_ADMIN
     173  $ trac-admin /path/to/projenv permission remove '*' REPORT_ADMIN
    115174}}}
    116175
    117176== Default Permissions ==
    118177
    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 
     178By 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.
     179On the other hand, the `authenticated` users will have the permissions to ''create and modify tickets and wiki pages''.
