Red Hat Bugzilla – Bug 201787
GDM can be used to test the existence of a user name
Last modified: 2007-11-30 17:11:39 EST
The GDM screen shows different error messages depending on the given user name.
If the user does not exist, a dialog box pops up ("Authentication failed"). If
just the password is wrong, there is an error message on the GDM screen saying
that the "password is wrong or the user does not exist".
