Automount home directories not being unmount upon logout

[misleb]

Hi,

I have hundreds of students who pull their desktops from the server. I am noticing that, quite often, student home directories don’t get unmounted when they log out. And when they go to log into another computer it says they are already logged in somewhere else.

I logged into one of the machines that had a “stale” server connection with a local admin account and tried to manually umount the “Users” folder and it says “resource busy.” I ran ‘lsof’ to see if any programs might be holding a file open on the network volume, but it didn’t show anything for that path.

Any idea what could be keeping the network share “busy” such that I can’t be unmounted on logout? Are there any tools besides lsof that might help troubleshoot this? I’m at the point where I am going to have to check “allow multiple logins” for all of my users just so they don’t have to keep coming to me to kick them off.

This is becoming more of a problem now that I have multiple home directory locations. A previous user’s home directory may remain mounted even when a new user logs in. Help!

BTW, this is all 10.4.10.. clients and servers.
