samba - Mar 2004 - Login on two workstations

Hi,

  I was wondering if it was possible to use a roll based login for Windows 
workstations, using samba as backend.

  Currently, using samba 2.2.8, I get the error on Windows XP that there are 
multiple instances for the same resource when I try to login with the same 
username on two workstations.  Is there a way to make this workable?


Mvh,
