------- Comment #1 from sfrench at us.ibm.com  2007-07-20 16:22 CST -------
The man page (for both smbfs and cifs) specifies:

       guest
          Don't prompt for a password

I agree that it would make sense for cifs to retry on authentication failure
with anonymous user (and also I agree that user mount should try to
authenticate with the user not user, although the issue of default uid/gid when
mounted to Windows ie bug 4780 needs to be fixed).

My initial reaction is that the man page behavior must be followed (no prompt),
and that we should attempt to authenticate with the "default" username (either
root if we are mounted as root or the user's uid if we are doing a user mount)
but that we should allow automatic retry (null user authentication, ie
"username=" ie an empty string) if root can not authenticate due to access
denied on session setup and perhaps one or two other errors (like a TConX
access denied failure).  If username  "root" can authenticate as "guest"
successfully, why retry as anonymous (null user)?
