I have this same problem. The affected user often ends up having file in use problems because of it. If she logs out of her workstation and logs back in, it also seems like she ends up logging back into the same open instance of her user account since all of her previous windows are open despite checking the box not to re-open apps at login.

There are some AFP disconnect settings you might want to explore... here's an article

What happens if you forcefully disconnect ONE of them?
The error that you get on your client computer will tell you exactly what's going on. If you don't get an error, then likely someone shut down without logging out, or properly disconnecting.
Just a thought.

After a little bit of mucking around I have discovered the duplicate user appears when I mount a network volume (which is also a share) during login using a "mount drive" script. I can disconnect the duplicate user which unmounts the network volume.
Same thing happens when I connect to the server machine through the SHARED listing in Finder as it is set up to use my network account to connect. ONce again I can disconnect which simply umounts the shared access.
