  • TracPermissions

    v3 v4  
    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 the ''General / Permissions'' panel in the ''Admin'' tab of the web interface.
    7 
    8 In 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.
    9 
    10 Non-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.
    11 In 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".
     6Permissions are managed using the [TracAdmin trac-admin] tool or 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 [TracIni#trac-permission_policies-option "[trac] permission_policies"]. See TracFineGrainedPermissions for more details.
     9
     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 privilege 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//.

    1313== Graphical Admin Tab
    1414
    1515To 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):
    16 {{{
    17   $ trac-admin /path/to/projenv permission add bob TRAC_ADMIN
    18 }}}
    19 
    20 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). '''Use at least one lowercase character in user names, as all-uppercase names are reserved for permissions.'''

    24  1. [[Image(htdocs:../common/guide/admin-permissions-TICKET_ADMIN.png)]]
    25 
    26 An 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.
     16{{{#!sh
     17$ trac-admin /path/to/projenv permission add bob TRAC_ADMIN
     18}}}
     19
     20Then, the user `bob` will be able to see the Admin tab, and can access the permissions menu. This menu will allow you to perform all the following actions, but from the browser rather than requiring root access to the server. '''Use at least one lowercase character in user names, as all-uppercase names are reserved for permissions.'''

    2727
    2828From 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.

    10296
    10397== Granting Privileges
    10498
    105 You grant privileges to users using [wiki:TracAdmin trac-admin]. The current set of privileges can be listed with the following command:
    106 {{{
    107   $ trac-admin /path/to/projenv permission list
     99You grant privileges to users using [TracAdmin trac-admin]. The current set of privileges can be listed with the following command:
     100{{{#!sh
     101$ trac-admin /path/to/projenv permission list
    108102}}}
    109103
    110104This command will allow the user ''bob'' to delete reports:
    111 {{{
    112   $ trac-admin /path/to/projenv permission add bob REPORT_DELETE
     105{{{#!sh
     106$ trac-admin /path/to/projenv permission add bob REPORT_DELETE
    113107}}}
    114108
    115109The `permission add` command also accepts multiple privilege names:
    116 {{{
    117   $ trac-admin /path/to/projenv permission add bob REPORT_DELETE WIKI_CREATE
     110{{{#!sh
     111$ trac-admin /path/to/projenv permission add bob REPORT_DELETE WIKI_CREATE
    118112}}}
    119113
    120114Or add all privileges:
    121 {{{
    122   $ trac-admin /path/to/projenv permission add bob TRAC_ADMIN
     115{{{#!sh
     116$ trac-admin /path/to/projenv permission add bob TRAC_ADMIN
    123117}}}
    124118
    125119== Permission Groups
    126120
    127 There are two built-in groups, "authenticated" and "anonymous".
    128 Any user who has not logged in is automatically in the "anonymous" group.
    129 Any user who has logged in is also in the "authenticated" group.
    130 The "authenticated" group inherits permissions from the "anonymous" group.
    131 For example, if the "anonymous" group has permission WIKI_MODIFY,
    132 it is not necessary to add the WIKI_MODIFY permission to the "authenticated" group as well.
     121There are two built-in groups, //authenticated// and //anonymous//.
     122Any user who has not logged in is automatically in the //anonymous// group.
     123Any user who has logged in is also in the //authenticated// group.
     124The //authenticated// group inherits permissions from the //anonymous// group.
     125For example, if the //anonymous// group has permission WIKI_MODIFY,
     126it is not necessary to add the WIKI_MODIFY permission to the //authenticated// group as well.
    133127
    134128Custom groups may be defined that inherit permissions from the two built-in groups.
    135129
    136130Permissions can be grouped together to form roles such as ''developer'', ''admin'', etc.
    137 {{{
    138   $ trac-admin /path/to/projenv permission add developer WIKI_ADMIN
    139   $ trac-admin /path/to/projenv permission add developer REPORT_ADMIN
    140   $ trac-admin /path/to/projenv permission add developer TICKET_MODIFY
    141   $ trac-admin /path/to/projenv permission add bob developer
    142   $ trac-admin /path/to/projenv permission add john developer
     131{{{#!sh
     132$ trac-admin /path/to/projenv permission add developer WIKI_ADMIN
     133$ trac-admin /path/to/projenv permission add developer REPORT_ADMIN
     134$ trac-admin /path/to/projenv permission add developer TICKET_MODIFY
     135$ trac-admin /path/to/projenv permission add bob developer
     136$ trac-admin /path/to/projenv permission add john developer
    143137}}}
    144138
    … …  
    149143
    150144The 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)
    151 {{{
    152    $ trac-admin /path/to/projenv permission add bob beta_testers
    153    $ trac-admin /path/to/projenv permission add beta_testers WIKI_ADMIN
    154 
     145{{{#!sh
     146$ trac-admin /path/to/projenv permission add bob beta_testers
     147$ trac-admin /path/to/projenv permission add beta_testers WIKI_ADMIN
    155148}}}
    156149
    … …  
    160153
    161154This command will prevent the user ''bob'' from deleting reports:
     155{{{#!sh
     156$ trac-admin /path/to/projenv permission remove bob REPORT_DELETE
     157}}}
     158
     159Just like `permission add`, this command accepts multiple privilege names.
     160
     161You can also remove all privileges for a specific user:
     162{{{#!sh
     163$ trac-admin /path/to/projenv permission remove bob '*'
     164}}}
     165
     166Or one privilege for all users:
     167{{{#!sh
     168$ trac-admin /path/to/projenv permission remove '*' REPORT_ADMIN
     169}}}
     170
     171== Creating New Privileges
     172
     173To 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 [TracIni#extra-permissions-section trac.ini]. For more information, please refer to the documentation  on the [TracIni#extra-permissions-section TracIni] page after enabling the component.
     174
     175== Default Permissions
     176
     177By 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.
     178On the other hand, the //authenticated// users will have the permissions to ''create and modify tickets and wiki pages''.
     179
     180//**anonymous**//

    165 
    166 Just like `permission add`, this command accepts multiple privilege names.
    167 
    168 You can also remove all privileges for a specific user:
