      -N      Do not ask for a password.  At run time, mount_smbfs reads the
              ~/.nsmbrc file for additional configuration parameters and a
              password.  If no password is found, mount_smbfs prompts 
for it.

Looks like mount_smbfs is expecting the file to be named '.nsmbrc', not 
simply 'nsmbrc.' So it's not finding the file where the password is stored.
