Could be! For some time after graduation, I used to have an account on Ohio State's undergrad (Solaris) CS system. I was in the `guest` group, for a reason I didn't really understand (my degree was a CS&E degree). Since then they've switched to using OSU's central password auth, so I doubt it works anymore. But it could also be that someone wants to keep your account active!
