[Samba] mount.cifs - trouble authenticating to a windows share

[erik.chakravarty at accenture.com]

Hi there
 
Firstly, you may want to check out this thread on Experts Exchange:
http://www.experts-exchange.com/Operating_Systems/Linux/Q_20815085.html
 
essentially this is my problem - I can connect to and browse a windows
file share with smbclient, but when i try to mount it with mount.cifs I
get errors. Note that this only happens when I have to authenticate to a
domain controller - I can use mount.smbfs to connect to a fileshare
using local windows authentication.
 
It's as if my username and password is incorrect
(NT_STATUS_LOGON_FAILURE) - but I have proved that I can authenticate
using smbclient - so the problem must be in the mounting process with
mount.cifs.
 
(see below - verbose output from kernel log (i have removed details like
username/password/server address):
 
viper:/var/log/samba# mount -t cifs -o
username="<DOMAIN\user.name>",uid=root,gid=root,rw //<server>/<share>/
/mnt      mount error 13 = Permission denied
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)
