I have a samba PDC with an openLDAP backend. on my windows 7 machines which have joined the Samba PDC domain I cannot see the groups on windows. Does anyone know the reason why ? The samba version is 3.6.9 I can see the mapped groups in groupmap list though root at smb-pdc[~]# net groupmap list Domain Admins (S-1-5-21-831610874-1793854533-4121639242-512) -> Domain Admins Domain Users (S-1-5-21-831610874-1793854533-4121639242-513) -> Domain Users DomaComputers (S-1-5-21-831610874-1793854533-4121639242-515) -> Domain Computers Builtin Power Users (S-1-5-21-831610874-1793854533-4121639242-547) -> Builtin Power Users Builtin Admins (S-1-5-21-831610874-1793854533-4121639242-544) -> Builtin Admins role_accounts_qbusers (S-1-5-21-831610874-1793854533-4121639242-1010) -> role_accounts_qbusers my Test Win (S-1-5-21-831610874-1793854533-4121639242-11276) -> role_my_test_win my Test Win2 (S-1-5-21-831610874-1793854533-4121639242-11278) -> role_my_test_win2 mytestgroup (S-1-5-21-831610874-1793854533-4121639242-1012) -> mytestgroup my SAMBA (S-1-5-21-831610874-1793854533-4121639242-11286) -> my_samba_group_test -- Please do let me know if there is anything else I can help you with Nana A.
