sasl_dispose - Dispose of a SASL connection object
#include <sasl.h>
void sasl_dispose(sasl_conn_t **pconn );
sasl_dispose is called when a SASL connection object is no
longer needed. Note that this is usually when the protocol
session is done NOT when the authentication is done since
a security layer may have been negotiated.
No return values
