Hello, > I have also noticed that with group set just to "compat" > with nscd turned on, that sometime nscd loses the NIS groups > and just reports the local groups. I have a very similar problem: With nscd running, when all user's account data comes from NIS, `groups user` often shows only the primary group of the user. Emptying nscd group cache data by running `nscd -i group` solves that. Regards Christoph
