In Fedora 19 alpha, I cannot log in as a FreeIPA user with an @ sign in the login name, such as fry.lan. [stef@stef-redhat ~]$ getent passwd fry.lan fry.lan:*:766000001:766000001:Philip Fry:/home/fry:/bin/sh I verified the home directory exists. The greeter completes, and GDM goes away, but then I either get stuck at a black screen with an old school X cursor, or get bounced back to the login screen. Installed Packages Name : gdm Arch : x86_64 Epoch : 1 Version : 3.8.0 Release : 2.fc19 This may not be a gdm issue. But need to track this down before reassigning.

I believe this has been fixed in GDM for a while now.
