Hi. I'm using samba-3.0.24 on a gentoo box. The samba machine is configured as a domain member server within a MS Windows 2003 active directory. It has been successfully joined to the domain and everything works, shares, kerberos, ldap. However, I cannot get nested groups to work, or more precisely, I cannot add a local group using net rpc. Here is what I am doing: gentoo ~ # net rpc group add NewGroup -Umyuser -L -d 3 -I 10.0.0.2 [2007/04/17 11:20:35, 3] param/loadparm.c:lp_load(4945) lp_load: refreshing parameters [2007/04/17 11:20:35, 3] param/loadparm.c:init_globals(1410) Initialising global parameters [2007/04/17 11:20:35, 3] param/params.c:pm_process(572) params.c:pm_process() - Processing configuration file "/etc/samba/smb.conf" [2007/04/17 11:20:35, 3] param/loadparm.c:do_section(3687) Processing section "[global]" [2007/04/17 11:20:35, 1] param/loadparm.c:lp_do_parameter(3426) WARNING: The "printer admin" option is deprecated [2007/04/17 11:20:35, 2] lib/interface.c:add_interface(81) added interface ip=10.0.0.1 bcast=130.88.255.255 nmask=255.255.0.0 [2007/04/17 11:20:35, 2] lib/interface.c:add_interface(81) added interface ip=127.0.0.1 bcast=127.255.255.255 nmask=255.0.0.0 Password: [2007/04/17 11:20:42, 3] libsmb/cliconnect.c:cli_start_connection(1426) Connecting to host=10.0.0.1 [2007/04/17 11:20:42, 3] lib/util_sock.c:open_socket_out(874) Connecting to 130.88.88.89 at port 445 [2007/04/17 11:20:42, 3] libsmb/cliconnect.c:cli_session_setup_spnego(721) Doing spnego session setup (blob length=122) [2007/04/17 11:20:42, 3] libsmb/cliconnect.c:cli_session_setup_spnego(746) got OID=1 2 840 113554 1 2 2 [2007/04/17 11:20:42, 3] libsmb/cliconnect.c:cli_session_setup_spnego(746) got OID=1 2 840 48018 1 2 2 [2007/04/17 11:20:42, 3] libsmb/cliconnect.c:cli_session_setup_spnego(746) got OID=1 3 6 1 4 1 311 2 2 10 [2007/04/17 11:20:42, 3] libsmb/cliconnect.c:cli_session_setup_spnego(754) got principal=cifs/samba-server@MY.REALM [2007/04/17 11:20:42, 3] libsmb/ntlmssp.c:ntlmssp_client_challenge(950) Got challenge flags: [2007/04/17 11:20:42, 3] libsmb/ntlmssp.c:debug_ntlmssp_flags(63) Got NTLMSSP neg_flags=0x60890215 [2007/04/17 11:20:42, 3] libsmb/ntlmssp.c:ntlmssp_client_challenge(972) NTLMSSP: Set final flags: [2007/04/17 11:20:42, 3] libsmb/ntlmssp.c:debug_ntlmssp_flags(63) Got NTLMSSP neg_flags=0x60080215 [2007/04/17 11:20:42, 3] libsmb/ntlmssp_sign.c:ntlmssp_sign_init(338) NTLMSSP Sign/Seal - Initialising with flags: [2007/04/17 11:20:42, 3] libsmb/ntlmssp.c:debug_ntlmssp_flags(63) Got NTLMSSP neg_flags=0x60080215 [2007/04/17 11:20:42, 3] rpc_client/cli_pipe.c:rpc_pipe_bind(2081) rpc_pipe_bind: Remote machine 10.0.0.1 pipe \lsarpc fnum 0x72a4 bind request returned ok.

Is it root on the gentoo box? Is it a domain admin on the windows active directory? Is it my wbinfo --set-auth-user definition? Is it some other account? I have tried all these combinations and I still cannot add a group. I know the root, domain admin account, wbinfo user passwords and still this just will not work for me. Can someone please inform me which account I should be using? As I have totally run out of ideas. Thanks Dave
