Hi everybody, I've configured SAMBA for joining the ADs of the place where i work, and everything is working fine. This means that with "getent passwd" i see all the local and the ADS users, i am also able to log into my machine via ssh by using the pam_winbind module and so on. I've configured some directories that are shared by samba and are property of their owners and also this thing is working fine. What i want to do now is to grant the write permission in a directory to a local group composed by ADs users. I've defined the directory in smb.conf : [TEST] comment = TEST path = /samba/TEST browseable = No public = No read only = Yes write list = @ADGROUP and created the group : #groupadd ADGROUP but it's impossible to modify the AD user by using usermod for including him in my group : # usermod -G ADGROUP MYDOMAIN+myuser0 usermod: MYDOMAIN+myuser0 not found in /etc/passwd and this for me is almost clear, because if usermod search only in passwd it will not find anything. So i've added manually the user to the group in the /etc/group file : # tail -1 /etc/group ADGROUP:x:1004:MYDOMAIN+myuser0,MYDOMAIN+myuser1,MYDOMAIN+myuser2 This seems to work, because if i run this command : # groups MYDOMAIN+myuser0 MYDOMAIN+myuser0 : MYDOMAIN+group1 ADGROUP i receive what i'm expecting to receive. The permission on the directory that i'm sharing are these : drwxrwx--- 2 root ADGROUP 4096 May 26 11:48 TEST But once restarted samba, i'm unable to access to this directory with the ADs user. What this problem maybe ? Is this a good way for proceding considering that i can't do any kind of modifications in the ADs server ? There's a better way to do what i wanto to do ? Let me know if i made myself clear and...Thanks for any help i will receive. -- RaSca "Il regno dei cieli e' simile ad un mercante che va in cerca di perle preziose.
