I have a newly upgraded Red Hat 9 Samba server (now ver. 3.04, formerly ver. 2.2.7a) on which I would like to start using ACLs to provide the NTFS style permissions. The problem I'm running into is figuring out how to map the NT User Account SIDs to the Unix UIDs. Every network user has an account on the Unix system with a name that matches their NT account name and I would like for there to be a 1 to 1 mapping between them. Is this possible? So far I've not been able to find anything in the docs except how to map to a UID from a given range that will not correspond to an already existing Unix account. If this info is already documented I would really appreciate a pointer towards it. Thanks. -- Michael St. Laurent Hartwell Corporation
