OK my problem is: - I Installed Samaba4 - I Created a Domain - Created users - Windows workstations Joined Domain - DNS is Bind9 Every thing is going OK for windows users. I am a windows administrator who started to convert for Linux lately so please be kind to explain a step by step please with examples so I can understand For examples who did you create the principle for NFS which is a service not a user using the samba-tool command as i couldn't understand what exactly dose that mean you added it as a machine or service and if there is a different. If you can reply with the needed steps to install NFS server and how to configure it to authenticate using kerberos authentication from Samba4 I would be thankful. -- View this message in context: http://samba.2283325.n4.nabble.com/Samba4-NFS-server-tp4643340.html Sent from the Samba - General mailing list archive at Nabble.com.
