                      5: the password, and answers with {}``unknown\_user'', {}``authorized''
                      6: or {}``non\_authorized''.
                      7: 
                      8: Determination if this is the user's homeserver is done by the presence

                     17: The password is stored in the format \texttt{mechanism:info}, where
                     18: mechanism can currently be unix, krb4 or internal. For krb4, the info
                     19: is the Kerberos domain, for internal it is the crypt password itself.
                     20: unix simply authenticates against /etc/passwd.
