cifs-utils is installed (2:5.1-1ubuntu1)

I don't really have visibility into the specifics here -- it is a NAS appliance of some kind managed by our IT and not under my control. However, smbclient identifies it as: OS=[EMC-SNAS:T5.6.50.205] Server=[NT1]

> Can you try a command like

ntlmsspi results in "operation not supported" but it doesn't seem to object to either the default ntlm or ntlmv2 as specified below:

$ sudo mount -t cifs //pc************.com/D******NAS2 /mnt/temp --verbose -o  domain=a******as,user=scott_purcell,password='******!***',uid=scott,gid=scott,rw,sec=ntlmv2

mount.cifs kernel mount options: ip=10.30.25.221,unc=\\pc************.com/D******NAS2,sec=ntlmv2,uid=1000,gid=1000,ver=1,user=scott_purcell,domain=a******as,pass=********
mount error(13): Permission denied
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)


> You can paste your smb.conf that smbclient uses as well.

With comments and blank lines stripped: 

$ grep -v ^# /etc/samba/smb.conf |grep -v ^$ |grep -v ^\;

I can invoke smbclient successfully by either referring it to my credentials file:


$ sudo smbclient  //pc************.com/D******NAS2 -A /etc/.smb_creds.txt

Or by specifying my authentication at the command line:

$ sudo smbclient  //pc************.com/D******NAS2 --workgroup=a******as --user=scott_purcell 
Enter scott_purcell's password: 
Domain=[A******AS] OS=[EMC-SNAS:T5.6.50.205] Server=[NT1]
