I've set up a bunch of groups using the standard template we use on campus for courses. Which is {course name}{number}.{semester code}. So an example would be chem2210.200802.
When I add users to this group and then display their expected permissions in the ACL manager, it always displays that they have no access to the pages/namespaces. However, if you log in with the account, you can access everything you are supposed to access.
I've attached a screenshot displaying this.
Not a major issue, since it works as expected, however, it would be nice for it to display correctly.
(I think there are other characters that also cause this issue to happen. I think _ for usernames caused me some grief when I first set this up)
