Trac uses a simple 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".
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.
Otherwise, individual privileges can be assigned to users for the various different functional areas of Trac (not that the privilege names are case-sensitive):

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
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.
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
Granting privileges to the special user anonymous can be used to control what an anonymous user can do before they have logged in.
In the same way, privileges granted to the special user authenticated will apply to any authenticated (logged in) user.
