Error 13 is EACCES. Nothing particular to CIFS stands out at me as
something that would throw this error at mount time. That probably
means that you're getting an error back from the server and that's
being translated to EACCES. Your best bet is probably to sniff traffic
with wireshark to track it down, but you may be able to gather a little
more info from turning up CIFS debugging:

# echo 7 > /proc/fs/cifs/cifsFYI

...you can turn it back off again after making the attempt by echoing 0
into that file.
