Admin Web UI: Copy permissions from one subject to another

[ethan.jucovy@…]

I often create new Trac environments where I need to restrict access for anonymous users, but want to provide all authenticated users with all the permissions that Trac grants out-of-the-box to anonymous users. This is not easy to do through the admin interface: I need to look at the list of permissions granted to "anonymous"; find each permission one by one in the "Grant Permission" dropdown; and submit the form repeatedly.

Also, I often grant permissions one at a time to specific users of my Trac environment, and only later realize that I want the same permissions to be shared by several users in a group. Transferring those permissions from a user to a group is a similarly time-consuming and error-prone process using the web interface.

A "Copy Permissions" feature would be very helpful for these situations. This could just be a form where the admin fills in a subject (user or group) and a target (user or group). The backend would then find all permissions that are currently granted directly to the subject, and would grant each of those permissions to the target.
