hello I would like to join a Netapp fileserver to a Samba domain that uses an external Openldap server for authentication. Here's what I do and where it goes wrong (I've hidden the real ip addresses). I've also created a machine account for the Netapp server on the PDC.: What is the name of the Windows NT 4 domain? [WORKGROUP]: PCKLAS CIFS - Starting SMB protocol... Wed Jul 5 17:08:47 CEST [filertop: nbt.nbss.socketError:error]: NBT: Cannot connect to server x.y.v.w over NBSS socket for port 139. Error 0xd: Permission denied. *** CIFS Setup could not establish a connection with the Primary Domain *** Controller (PDC). Usually this happens when the 'FILERTOP' account *** does not exist in the domain or must have it's password reset. Once you have created and/or reset the 'FILERTOP' machine account, press ENTER.
