Trac Permissions
Table of Contents
Trac uses a simple, case sensitive, permission system to control what users can and can't access.
Permission privileges are managed using the trac-admin tool.
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. 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".
Available Privileges
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 to perform any operation.
Otherwise, individual privileges can be assigned to users for the various different functional areas of Trac (note that the privilege names are case-sensitive):

Creating New Privileges
(From http://nil.checksite.co.uk/index.cfm/2008/1/14/trac-0-11-creating-your-own-permissions)
To add permissions to Trac 0.11 you simply need to add a myPermissions.py file to your Trac environment plugin folder that looks like this:
from trac.core import Component, implements
from trac.perm import IPermissionRequestor
class MyPermissions(Component):
implements(IPermissionRequestor)
def get_permission_actions(self):
#comma separated list of new permissions
return ('TICKET_CLOSE','TICKET_DEFER')
Add your set of permissions to the return command in place of 'MY_FIRST_PERM', 'MY_SECOND_PERM', restart apache and you should be away.
You can now use these permission in your work flow against actionname.permissions entries.
NOTE: you don't need to call the file "myPermissions.py" - its just needs to be a python file with a name of your choosing.
Granting Privileges
You grant privileges to users using trac-admin. The current set of privileges can be listed with the following command:
$ trac-admin /path/to/projenv permission list
This command will allow the user bob to delete reports:
$ trac-admin /path/to/projenv permission add bob REPORT_DELETE
The permission add command also accepts multiple privilege names:
$ trac-admin /path/to/projenv permission add bob REPORT_DELETE WIKI_CREATE
Or add all privileges:
$ trac-admin /path/to/projenv permission add bob TRAC_ADMIN
Permission Groups
There are two built-in groups, "authenticated" and "anonymous".
Any user who has not logged in is automatically in the "anonymous" group.
Any user who has logged in is also in the "authenticated" group.
The "authenticated" group inherits permissions from the "anonymous" group.
eg. if the "anonymous" group has permission WIKI_MODIFY, it's not necessary to add the WIKI_MODIFY permisison to the "authenticated" group as well.
Custom groups may be defined that inherit permissions from the two built-in groups.
Permissions can be grouped together to form roles such as developer, admin, etc.
$ trac-admin /path/to/projenv permission add developer WIKI_ADMIN $ trac-admin /path/to/projenv permission add developer REPORT_ADMIN $ trac-admin /path/to/projenv permission add developer TICKET_MODIFY $ trac-admin /path/to/projenv permission add bob developer $ trac-admin /path/to/projenv permission add john developer
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.
Adding a New Group and Permissions
Permission groups can be created by assigning a user to a group you wish to create, then assign permissions to that group.
The 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)
$ trac-admin /path/to/projenv permission add bob beta_testers $ trac-admin /path/to/projenv permission add beta_testers WIKI_ADMIN
Removing Permissions
Permissions can be removed using the 'remove' command. For example:
This command will prevent the user bob from deleting reports:
$ trac-admin /path/to/projenv permission remove bob REPORT_DELETE
Just like permission add, this command accepts multiple privilege names.
You can also remove all privileges for a specific user:
$ trac-admin /path/to/projenv permission remove bob '*'
Or one privilege for all users:
$ trac-admin /path/to/projenv permission remove '*' REPORT_ADMIN
Default Permissions
By default on a new Trac installation, the anonymous user will have view access to everything in Trac, and will also have permissions to create and modify tickets and wiki pages.
