Hi List, We have a pretty complex samba configuration running version 3.0.21 , this worked for about 2 years , but due to security reasons we need to upgrade to latest version 3.0.28. I have no local unix users created on our host all access is regulated via the valid user = @AD+group statement . and the net groupmap add command. This worked great , but seems broken in latest versions since 3.0.23 I checked the latest howtos , but no success , seems that i overlooked some essentials... Now my smb.conf (only the relevant lines) ---------------- workgroup = WWxxx server string = 47556.@emailaddress security = DOMAIN netbios name = ATWS26QC encrypt passwords = Yes client schannel = no client use spnego = no server signing = auto config file = /usr/local/samba/lib/smb.conf password server = vieg10wa passdb expand explicit = no password level = 1 winbind uid = 100000-130000 winbind gid = 100000-120000 winbind enum users = yes winbind enum groups = yes winbind separator = + winbind use default domain = yes winbind nested groups = yes #the shares [home2] path = /home2 valid users @sbs_ors_ux @sbs_ors read only = no browseable = yes ---------------------- output from net groupmap list -------------------------- # bin/net groupmap list Administrators (S-1-5-32-544) -> 100000 sbs_ors (S-1-5-21-3932861455-2822179577-2594212704-125693) -> sbs_ors_ux ----> thats the relevant group Users (S-1-5-32-545) -> 100001 ------------------------ But I cant get it to work , I?m allways asked for a password , but should work seemless , as it does with "old" samba version Hope theres someone who can give me some hints , like a working smb.conf and or a howto to manage the "net groupmap add" command in the proper way Best regards Martin Martin Schreiber Siemens IT Solutions and Services GmbH Gudrunstrasse 11 A-1101 Wien Tel: +43(0)51707 47565 Fax: +43(0) 51707 57560 martin.a.schreiber@siemens.com http://www.siemens.at/it-solutions Siemens IT Solutions and Services GmbH, DVR 1009192, FN 180547k, Handelsgericht Wien, Firmensitz Wien Wichtiger Hinweis: Diese E-Mail kann Betriebs- oder Gesch?ftsgeheimnisse oder sonstige vertrauliche Informationen enthalten.
