Just upgraded to Precise and am working to restore access to the windows shares I use at work.

smbclient connects immediately:
Code:
sudo smbclient //pc1n7i01d03.us.dell.com/dttuatnas2 -A /etc/.smb_creds.txt
mount.cifs fails (with "mount error(13): Permission denied"):
Code:
sudo mount.cifs //pc1n7i01d03.us.dell.com/dttuatnas2 /mnt/ -o credentials=/etc/.smb_creds.txt
my credentials file is as follows (with the proper values, of course):

Code:
username=mynamehere
password=password
domain=MyDomain
I remember on a previous occasion having resolved a problem by including a mount option "noserverino". I've tried that to no effect. I've also tried "sec=ntlmv2"

The syslog contains this message in response to each failed attempt:

Code:
CIFS VFS: cifs_mount failed w/return code = -13
I'm baffled and appreciative of any suggestions you can provide. Thanks in advance.
