It seems to be limited to logins for certain hardware and account combinations, but there have been some inconsistencies in the reporting so we’re not completely sure. When it does happen on a machine for a particular user, it seems to happen consistently for that user on that machine, perhaps with the exception of the first login after a reboot. > > I’m running into it on my Debathena Workstation install as well.

While the machines look fine, when I have the TAs for a summer course in the labs use the machines, they get oddities like: > > * After using a machine with no issues, they try to log back onto the machine only to find that they can’t. > > * They may get randomly logged out of a machine, then find they cannot log back into it. > > Just to add to the confusion, it’s not all of the machines even though they were installed at the same time and I haven’t managed to get this behavior to happen with my account yet. > > Is there something that I could have done with the Debathena Workstation install that is causing people’s accounts to die during login? > > -Fletch > > >
