Description of problem: Something appears to have gotten lost or broken between gdm in FC3 (current) and gdm in FC4-T3 (current development). If a user enters an incorrect username or password, under FC3 there was a delay and an error message was displayed when using the graphical greeter but this is NOT occuring with FC4T3 [the standard greeter still displayes an error message]. It does not appear to matter what gdm graphical greeter theme is used.
should be fixed in tomorrow's rawhide.
