Hello list, I'm using samba/winbind (rhel4, samba-3.0.10, w2k-dc) for single sign on for windows users . When logged on to the linux mashine they run an application, which checks if the user has the same group rights ( appl. has local Unix-user/group "app", so the windows user should also be member of this group). I've tried with group mapping (map "app" to "domain-users"), but it didn't work. While reading the howto it looks to me, as groupmapping is for integrating unix into windows. i need it the other way. did i get something wrong? thx for your help! kind regards, stef.
