That is how it is supposed to work, if a known user tries to use a
wrong password, the user is rejected. If the user is unknown, it is
mapped to the guest user (usually 'nobody') and allowed access to
shares where 'guest ok = yes' is set.

need more info, what is in the [global] section of the smb.conf ?
