Some patches to authentication:

 - the usersupplied_info now contains a smb_username (as it comes across on
   the wire) and a unix_username (after being passed through mapping
   functions)

 - when doing security={server,domain} use the smb_username, otherwise use
   the unix_username
(This used to be commit d34fd8ec0716127c7a68eeb8e77d1ae8cc07b547)
