What about using the option as suggested in the man page:

mount -t cifs -o user=guest //wall/pub /mnt --verbose

Actually, mount.cifs could maybe give a more explicit warning about
"-o user" not being supported.

To be more complete:

root at mykerinos:~> mount -t cifs -o user=spongebob //localhost/public /mnt
Password:
root at mykerinos:~> umount /mnt
root at mykerinos:~> mount -t smbfs -o user=spongebob //localhost/public /mnt
Password:
20678: tree connect failed: ERRDOS - ERRnoaccess (Access denied.)
SMB connection failed
root at mykerinos:~> mount -t smbfs -o username=spongebob //localhost/public /mnt
Password:
root at mykerinos:~> umount /mnt


mount.cifs supports "-o user=foo" while mount.smbfs doesn't and
requires "-o username=foo"

As far as I know "-o foo" does not work with mount.smbfs either:

root at mykerinos:~> mount -t smbfs -o spongebob //localhost/public /mnt
Password:
20700: tree connect failed: ERRDOS - ERRnoaccess (Access denied.)
SMB connection failed
