I have a Windows Server 2003 system I'm trying to back up to a Linux host.

when I access the share with smbclient, I can "see" the files (`ls` returns a
list of files, etc)

smbclient -U shareuser //server/sharename password

But, when I try to actually mount the drive, I get "permission denied" errors
trying to access the drive. (EG: using `df`) Running the following command
takes about 10 seconds:

smbmount //server/sharename /mnt/servername -o \
credentials=/path/to/credentials,ro
