Hello, We have following environment Win2k AD with "endless" number of groups (should be more then 1000) , on the other site solaris9 samba3.0.7 compiled with all relevant optins , winbind , ads and so on , installations is ok , we joined AD domain w.o problems , getent * shows all like expected same for wbinfo The big problem remaining is , we want to restrict access to shares to given AD groups that way: valid users = @ADDOMAIN+ADGROUP that doesnt work in any combination, the other way valid users = @ADDOMAIN+ADUSERNAME works without any probem there is no user or groupmapping at all -----------------------output from level 10 log---------------------------------- 2004/10/21 17:16:44, 10] lib/username.c:user_in_list(533) user_in_list: checking user |WW300+atw113c9| against |admoss| [2004/10/21 17:16:44, 10] lib/username.c:user_in_list(533) user_in_list: checking user |WW300+atw113c9| against |ww300+csi| [2004/10/21 17:16:44, 10] lib/username.c:user_in_list(610) user_in_list: checking if user |WW300+atw113c9| is in winbind group |ww300+csi| [2004/10/21 17:16:49, 10] lib/username.c:user_in_winbind_group_list(412) user_in_winbind_group_list: using groups -- 30001 30002 30003 30004 30005 30006 30007 30008 30009 300 10 30011 30012 30013 30014 30015 30016 [2004/10/21 17:16:49, 2] smbd/service.c:make_connection_snum(314) user 'WW300+atw113c9' (from session setup) not permitted to access this share (pst) [2004/10/21 17:16:49, 3] smbd/error.c:error_packet(129) ---------------------------------------------------------------------------- ----------------- as i think winbind can only reflect to first 16 or 17 groups user_in_list checks the right group name , in this case ww300+admoss , but user_in_winbind_group_list shows only the first 16 mapped groups , as we have more then 1000 or 2000 and nested groups i can never be authenticated Now my Siemens Business Services CCN-ITS Betrieb Wien GUD Gudrunstrasse 11 A-1101 Wien Martin Schreiber Phone +43 5 1707 47565 Server-Administration Fax +43 5 1707 57560 mailto:martin.a.schreiber@siemens.com http://www.sbs.at
