Hi everyone, Can anyone tell me if it's possible to authenticate if a user is member of certain group and how to do this ? For example : I only want to authenticate user x for my imap-mailserver whose primary group is "users" if he/she is also a member of the group "mail". Same thing for ssh,ftp,... Tnx a lot in advance for any help Kind Regards, -- Thomas E-mail: Thomas.Delaet@student.kuleuven.ac.be
