* Implementation of the SASL EXTERNAL mechanism.
*
* To effectively use this mechanism, Java must be configured to properly
* supply a client SSL certificate (of some sort) to the server. It is up
* to the implementer to determine how to do this. Here is one method:
*
* Create a java keystore with your SSL certificate in it:
* keytool -genkey -alias username -dname "cn=username,ou=organizationalUnit,o=organizationaName,l=locality,s=state,c=country"
*
* Next, set the System Properties:
* <ul>
* <li>javax.net.ssl.keyStore to the location of the keyStore
* <li>javax.net.ssl.keyStorePassword to the password of the keyStore
* <li>javax.net.ssl.trustStore to the location of the trustStore
* <li>javax.net.ssl.trustStorePassword to the the password of the trustStore
* </ul>
*
* Then, when the server requests or requires the client certificate, java will
* simply provide the one in the keyStore.
*
* Also worth noting is the EXTERNAL mechanism in Smack is not enabled by default.
* To enable it, the implementer will need to call SASLAuthentication.supportSASLMechamism("EXTERNAL");
