Sorry – I dont have a step-by-step guide  If you need that please engage professional services.  It really depends on your very specific setup and how much mapping and permission/access is enough for your environment.  You need to figure it out and test it yourself. That’s why I recommendet getting a Simulator. There you can quickly go back to clean config  First step would be to carefully read the half dozen manuals that are related to multi-protocol and user mapping.  The groups file is a Unix file – it doesn’t contain SIDs – it contains mapping of names to GID  Rainer
