/**
* Builds and sends the <tt>auth</tt> stanza to the server. Note that this method of
* authentication is not recommended, since it is very inflexible. Use {@link
* #authenticate(String, String, CallbackHandler)} whenever possible.
*
* <p>Explanation of auth stanza:
*
* <p>The client authentication stanza needs to include the digest-uri of the form:
* xmpp/serviceName From RFC-2831: digest-uri = "digest-uri" "=" digest-uri-value digest-uri-value
* = serv-type "/" host [ "/" serv-name ]
*
* <p>digest-uri: Indicates the principal name of the service with which the client wishes to
* connect, formed from the serv-type, host, and serv-name. For example, the FTP service on
* "ftp.example.com" would have a "digest-uri" value of "ftp/ftp.example.com"; the SMTP server
* from the example above would have a "digest-uri" value of "smtp/mail3.example.com/example.com".
*
* <p>host: The DNS host name or IP address for the service requested. The DNS host name must be
* the fully-qualified canonical name of the host. The DNS host name is the preferred form; see
* notes on server processing of the digest-uri.
*
* <p>serv-name: Indicates the name of the service if it is replicated. The service is considered
* to be replicated if the client's service-location process involves resolution using standard
* DNS lookup operations, and if these operations involve DNS records (such as SRV, or MX) which
* resolve one DNS name into a set of other DNS names. In this case, the initial name used by the
* client is the "serv-name", and the final name is the "host" component. For example, the
* incoming mail service for "example.com" may be replicated through the use of MX records stored
* in the DNS, one of which points at an SMTP server called "mail3.example.com"; it's "serv-name"
* would be "example.com", it's "host" would be "mail3.example.com". If the service is not
* replicated, or the serv-name is identical to the host, then the serv-name component MUST be
* omitted
*
* <p>digest-uri verification is needed for ejabberd 2.0.3 and higher
*
* @param username the username of the user being authenticated.
* @param host the hostname where the user account resides.
* @param serviceName the xmpp service location - used by the SASL client in digest-uri creation
* serviceName format is: host [ "/" serv-name ] as per RFC-2831
* @param password the password for this account.
* @throws SmackException If a network error occurs while authenticating.
* @throws NotConnectedException
