Hello everybody, 1. Question When migration from an nt4 style domain to a new samba 3 style domain with ldapsam , it is necessary to preserve the old SIDs of the user to keep the users in touch with the old servers. M$ calles this SID history, which means that the old SID is added to new accounts in an AD. Does samba have any equal mechanism? 2. Question Does net rpc vampire preserve domain trust accounts?
