I'm trying to mount shares from our OSX server (10.11.5) onto my linux client (Ubuntu 15.10) after an upgrade to the server took place. Prior to the upgrade I was able to mount these directories without a problem using fstab entries like this:
//Server/Share /mnt/server/share cifs user=<user>,nounix,noauto,rw,uid=<user>,gid=<user> 0 0
However, after the upgrade I get the follow messages:
mount error(11): Resource temporarily unavailable Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
I also cannot mount the shares from Nautilus. Other Mac clients ARE able to mount the shares. The linux client is able to mount SMB shares from other Ubuntu servers.
smbclient gives the following:
ntlmssp_handle_neg_flags: Got challenge flags[0x22810205] - possible downgrade detected! missing_flags[0x00080000] - NT code 0x80090302 NTLMSSP_NEGOTIATE_EXTENDED_SESSIONSECURITY SPNEGO(ntlmssp) login failed: NT code 0x80090302 session setup failed: NT code 0x80090302
Which suggests issues with
ntlmssp authentication. I have tried various
sec= additions to fstab but to no avail.
sudo serveradmin settings smb output is as follows.
smb:ntlmv2 = no smb:ntlmAuth = yes smb:ServerDescription = "<REMOVED>" smb:ntlmv2 auth = no smb:wins server:_array_index:0 = _empty_dictionary smb:spnego = no smb:DOSCodePage = "437" smb:NetBIOSName = "<REMOVED>" smb:VirtualAdminShares = no smb:logging = yes smb:ntlm auth = yes smb:AllowGuestAccess = no smb:ntlmv2Auth = no smb:LocalKerberosRealm = "<REMOVED>"
I have very little access to the OSX server and do not know the details of the upgrade (imperfect world I know). I am not officially in a position to make changes to the server directly but can request specific things be done.
Mounting in this direction (Ubuntu client, OSX server) appears uncommon and so I would appreciate any help, advice or even thoughts people might be willing to share.
