    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.
    55
    6 Permission privilegies are managed using the [wiki:TracAdmin trac-admin] tool.
     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.
    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 privilegies 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".

    15 === Available privileges ===
     13== Graphical Admin Tab ==
     14''This feature is new in version 0.11.''
    1615
    17  * {{{TRAC_ADMIN}}}
    18  * {{{LOG_VIEW}}}
    19  * {{{FILE_VIEW}}}
    20  * {{{CHANGESET_VIEW}}}
    21  * {{{BROWSER_VIEW}}}
    22  * {{{TICKET_VIEW, TICKET_CREATE, TICKET_MODIFY, TICKET_ADMIN}}}
    23  * {{{REPORT_VIEW, REPORT_CREATE, REPORT_MODIFY, REPORT_DELETE, REPORT_ADMIN, REPORT_SQL_VIEW}}}
    24  * {{{WIKI_VIEW, WIKI_CREATE, WIKI_MODIFY, WIKI_DELETE, WIKI_ADMIN}}}
    25  * {{{MILESTONE_VIEW, MILESTONE_CREATE, MILESTONE_MODIFY, MILESTONE_DELETE}}}
    26  * {{{ROADMAP_VIEW, ROADMAP_ADMIN}}}
    27  * {{{TIMELINE_VIEW}}}
    28  * {{{SEARCH_VIEW}}}
    29  * {{{CONFIG_VIEW}}}
     16To access this tab, a user must have `TRAC_ADMIN privileges`. This can be performed as follows (more on the trac-admin script below):
     17{{{
     18  $ trac-admin /path/to/projenv permission add bob TRAC_ADMIN
     19}}}
    3020
    31 The {{{something_ADMIN}}} privileges are just shortcuts that can be used to grant a user all the ''something'' privileges in one go. Having {{{TRAC_ADMIN}}}
    32 is like being {{{root}}} on a *NIX system, it will let you do anything you want.
     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).
    3322
    34 === Granting privileges ===
    3523
    36 Currently the only way to grant privileges to users is by using the
    37 {{{trac-admin}}} script. The current set of privileges can be listed
    38 with the following command:
     24An 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.
    3925
     26== Available Privileges ==
     27
     28To 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.
     29
     30Otherwise, individual privileges can be assigned to users for the various different functional areas of Trac ('''note that the privilege names are case-sensitive'''):

     94
     95== Granting Privileges ==
     96
     97You grant privileges to users using [wiki:TracAdmin trac-admin]. The current set of privileges can be listed with the following command:
    4098{{{
    4199  $ trac-admin /path/to/projenv permission list
    42100}}}
    43101
    44 This command will let the user ''bob'' delete reports:
    45 
     102This command will allow the user ''bob'' to delete reports:
    46103{{{
    47104  $ trac-admin /path/to/projenv permission add bob REPORT_DELETE
    48105}}}
    49106
    50 === Permission groups ===
     107The `permission add` command also accepts multiple privilege names:
     108{{{
     109  $ trac-admin /path/to/projenv permission add bob REPORT_DELETE WIKI_CREATE
     110}}}
    51111
    52 Permissions can be grouped together to form roles such as
    53 ''developer'', ''admin'', etc.
     112Or add all privileges:
     113{{{
     114  $ trac-admin /path/to/projenv permission add bob TRAC_ADMIN
     115}}}
    54116
     117== Permission Groups ==
     118
     119There are two built-in groups, "authenticated" and "anonymous".
     120Any user who has not logged in is automatically in the "anonymous" group.
     121Any user who has logged in is also in the "authenticated" group.
     122The "authenticated" group inherits permissions from the "anonymous" group.
     123For example, if the "anonymous" group has permission WIKI_MODIFY,
     124it is not necessary to add the WIKI_MODIFY permission to the "authenticated" group as well.
     125
     126Custom groups may be defined that inherit permissions from the two built-in groups.
     127
     128Permissions can be grouped together to form roles such as ''developer'', ''admin'', etc.
    55129{{{
    56130  $ trac-admin /path/to/projenv permission add developer WIKI_ADMIN
     
    61135}}}
    62136
    63 === Default permissions ===
     137Group 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'''.
    64138
    65 Granting privileges to the special user ''anonymous'' can be used to control
    66 what an anonymous user can do before they have logged in.
     139== Adding a New Group and Permissions ==
     140Permission groups can be created by assigning a user to a group you wish to create, then assign permissions to that group.
    67141
    68 In the same way, privileges granted to the special user ''authenticated'' will apply to any authenticated (logged in) user.
     142The 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)
     143{{{
     144   $ trac-admin /path/to/projenv permission add bob beta_testers
     145   $ trac-admin /path/to/projenv permission add beta_testers WIKI_ADMIN
    69146
     147}}}
     148
     149== Removing Permissions ==
     150
     151Permissions can be removed using the 'remove' command. For example:
     152
     153This command will prevent the user ''bob'' from deleting reports:
     154{{{
     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{{{
     162  $ trac-admin /path/to/projenv permission remove bob '*'
     163}}}
     164
     165Or one privilege for all users:
     166{{{
     167  $ trac-admin /path/to/projenv permission remove '*' REPORT_ADMIN
     168}}}
     169
     170== Default Permissions ==
     171
     172By 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.
     173On the other hand, the `authenticated` users will have the permissions to ''create and modify tickets and wiki pages''.
