Logon only once

We've found a solution for this problem but I don't know whether
you can use it.

Principle of the script:

A user logs in.

We check on the server if a file exists with this username.
If not, we create one and the user may log in.
If the file exists ==> he has already logged in once, further access is

The user logs out.

The file with his name is being removed.

I've tested this and it seems to work but we've never used it in production
we've have 500 PC's and thought that this would slow down the logon process.

I'm setting up a lab full of users here at the college and really need
to be able to restrict a user to a single login at any given time.  Does
anyone have any thoughts or suggestions about this?

Once the user has logged in at a workstation they wouldn't be able to
use another workstation until they logged out of the one they were on.

This is the difference between using Samba and going with Netware.  I'd
REALLY appreciate anyone who can help me with this.
