Trac Permissions

Trac uses a flexible permission system to control what different users can do in the system.

When a user first uses a system he/she will be able to do certain things. Exactly what he/she can do depend on which privileges you have granted to the special user anonymous. In addition to these privileges different users can be granted additional rights as soon as they login into the system.

Available privileges

• TRAC_ADMIN
• LOG_VIEW
• FILE_VIEW
• CHANGESET_VIEW
• BROWSER_VIEW
• TICKET_VIEW, TICKET_CREATE, TICKET_MODIFY, TICKET_ADMIN
• REPORT_VIEW, REPORT_CREATE, REPORT_MODIFY, REPORT_DELETE, REPORT_ADMIN
• WIKI_VIEW, WIKI_CREATE, WIKI_MODIFY, WIKI_DELETE, WIKI_ADMIN
• TIMELINE_VIEW
• SEARCH_VIEW
• CONFIG_VIEW

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 is like being root on a *NIX system, it will let you do anything you want.

Granting privileges

Currently the only way to grant privileges to users is by using the trac-admin script. The current set of privileges can be listed with the following command:

  $ trac-admin /path/to/projenv permission list

This command will let the user bob to delete reports:

  $ trac-admin /path/to/projenv permission add bob REPORT_DELETE

Permission 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

Default permissions

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.
