I have a new Samba installation that I wish to become a fileserver for several people. I would like to authenticate them to the main company domain, and am trying to figure out the best way to do so. I have looked into winbind, and seem to be running into a serious problem. The main domain and all the trusted domains add up to nearly 130,000 users. This causes grief for winbind since it tries to map all these users to uids, and there aren't enough available. The end result that I want is to have the small group of users in my department to have nearly transparent file access. IE, if they are logged into their machine with their domain account, they simply type \\server\share and have access with no username prompts. If they are on a machine not joined to the domain, then they should be able to type DOMAIN\user as their username, and have the password work. What is the minimal setup I need to accomplish this? Can I set up winbind in a way that prevents it from mapping every user account in existence to a uid? All the users I want to have access are all part of one domain, but it is still rather large. Thanks, Tom
