Hi Ok so I have samba setup and started and I have successfully joined the AD domain and can see the Linux server in Microsoft Active Directory Users and Groups applet. I can also log on and browse a server from the lnux server using: "kinit administrator@LAB.COM " - where LAB.COM is the AD Domain and the doing a "smbclient //W2KSVR/c\$ -k" - where W2KSVR is the W2003 server So all that is fine !!! I Hope !!!!... So now how do I go about giving users from Active Directory permissions to the shares on the linux server ? I try from Windows by right clicking on the linux folder and going to the security tab but can only choose users from the linux server.I cannot select to add users from the AD ? The linux server by the way is SLES 9.1 with Samba 3.0.2a Apologies if this question is obvious to everyone but I am a newcommer. Thanks Shiraaz
