/**
* Creating a JNDI connection using JBoss Remoting.
*
* If Context.SECURITY_PRINCIPAL and Context.SECURITY_CREDENTIALS are set,
* this InitialContextFactory implementation combines the
* authentication phase with the InitialContext creation. During the
* getInitialContext callback from the JNDI naming, layer security context
* identity is populated with the username obtained from the
* Context.SECURITY_PRINCIPAL env property and the credentials from the
* Context.SECURITY_CREDENTIALS env property. There is no actual authentication
* of this information. It is merely made available to the jboss transport
* layer for incorporation into subsequent invocations. Authentication and
* authorization will occur on the server.
*
* If Context.SECURITY_PROTOCOL is provided as well as the principal and credentials,
* then a JAAS login will be performed instead using the security domain provided with the
* SECURITY_PROTOCOL variable.
