I have a Synology NAS that uses Samba 3.6.9. I also have a Windows Domain Controller (Server 2012 R2) that I'm using Windows Server Backup on to backup the System State to the Synology NAS. When using SMB1, I have no issues, however, when using SMB2, I run into the following:
smbd/service.c:636: [2014/01/04 14:56:11.044645, all 2, pid=20301] create_connection_session_info user 'NAUPLIUS\dc01$' (from session setup) not permitted to access this share (Backup) smbd/service.c:847: [2014/01/04 14:56:11.045532, all 1, pid=20301] make_connection_snum create_connection_session_info failed: NT_STATUS_ACCESS_DENIED smbd/service.c:1453: [2014/01/04 14:56:20.283879, all 1, pid=20301] close_cnum DC01 (10.10.20.8) closed connection to service Backup smbd/connection.c:35: [2014/01/04 14:56:20.284802, all 3, pid=20301] yield_connection Yielding connection to Backup smbd/smb2_server.c:3120: [2014/01/04 14:56:20.289760, all 2, pid=20301] smbd_smb2_request_incoming smbd_smb2_request_incoming: client read error NT_STATUS_CONNECTION_RESET smbd/server_exit.c:181: [2014/01/04 14:56:20.293909, all 3, pid=20301] exit_server_common Server exit (NT_STATUS_CONNECTION_RESET)
As you can see, Windows Server Backup in this case is attempting to access the share with the Computer Account. Now, if this was a Windows Server, Computer accounts can be added to a Windows Share just as easily as a User account. From what I gather, that is not the case with Samba. Can someone correct me if I'm wrong, is it possible to add a Domain Computer account to the Samba Share permissions?
One thing to note is I did add "NAUPLIUS\Domain Controllers" (which DC01 is a member of), but that does not appear to have resolved the issue. The NT_STATUS_ACCESS_DENIED errors continue.
