[Samba] What triggers a make_user_info_map

We have a quite large samba installation/domain spanning 4 campuses with a 
DC/LDAP on every campus.

On one campus, one big computer-lab behaves a bit strange. All the computers 
connects to the DC every 2-3 minutes or so and triggers a make_user_info_map
mapping 100-300 or so  username's to RID's.
This places high load on the LDAP-server.

It doesn't matter if anyone is logged on. They do this around the clock!

The lab is reinstalled and is not configured any differently than all the 

I can't find any reason for this behavior. 

Anyone out there got a clue?
