New SAMBA PDC does not run logon script

Hello, everyone. I have my new server (SuSE 8.1 Pro) up and running, but there are a couple of nagging issues with Samba. I have transferred my old Samba settings/files to my new server, and my shares all show up fine, and I can map drives as before. However, the logon script no longer runs when a user logs in on a client PC. I mainly use this file to map the drives to the correct share, which I have been able to set up manually. My concern is that this problem points to Samba not being set up properly, which bothers me a great deal. Anyone else had a similar problem and managed to overcome it ? I have installed the latest Samba updates via YOU, but that didn't help. Thanks, Stuart.
