Hi All, when i did testing with group mapping, i mapped a Unix Group(domadm) with Windows Domain Group(domain users). then i access a samba share from Windows Domain User(administrator), and create a file. but the file's group is still Windows Domain Group(domain user), not Unix Group(domadm). is it right? if it is, how should i check if my group mapping is working well? thanks a lot in advance. following is my steps. 1. create unix group & users. test01:/var/lib/samba # getent group domadm domadm:!:1007:usr5 2. map "domadm" to Windows group "Domain Users" test01:/var/lib/samba # net groupmap add unixgroup="domadm" ntgroup="Domain Users" type=d No rid or sid specified, choosing a RID Got RID 3015 Successfully added group Domain Users to the mapping db as a domain group #check mapping test01:/var/lib/samba # net groupmap list Domain Users (S-1-5-21-495323680-4097577397-3625727858-3015) -> domadm #check members test01:/var/lib/samba # net rpc group members "Domain Users" -Uroot Enter root's password: test\usr5 3. access a samba share from Windows XP with user "administrator", then create a file. 4. ls -l the file: test01:/vx/fs1 # ls -l New\ Text\ Document.txt -rwxr--r-- 1 administrator domain users 0 Oct 27 07:46 New Text Document.txt the file's group is still "domain users". should it be "domadm"? Thanks,
