s3:auth Make Samba3 use the new common struct auth_usersupplied_info
This common structure will make it much easier to produce an auth module for s3compat that calls Samba4's auth subsystem. In order the make the link work properly (and not map twice), we mark both that we did try and map the user, as well as if we changed the user during the mapping.
