hi i have a user ~# id test_user uid=500,gid=500 (users),groups (users,kids) as you can see, this user is in primary group "users" and also member of group "kids" if he tries to access /home/board via smb (Samba 3.0 + openldap) from a windows client (XP), he fails, because his sambaPrimaryGroupSID maps to -> "users" and /home/board is not accessible for

...I am not shure if i got you right. You do not tell us the access rights of the directory concerned. If you'r primary uninx group is user and your dir. has: drwx---rwx root user board they forbid your access. then you are not allowed to access, because group rights match first and If you weren't user but world, then you would be allowed. This has nothing to do with samba. You might want to change the group to nogr...
