Sets the underlying delegate {@link SessionManager} instance that will be used to support this implementation's
<tt>SessionManager</tt> method calls.
<p/>
This <tt>SecurityManager</tt> implementation does not provide logic to support the inherited
<tt>SessionManager</tt> interface, but instead delegates these calls to an internal
<tt>SessionManager</tt> instance.
<p/>
If a <tt>SessionManager</tt> instance is not set, a default one will be automatically created and
initialized appropriately for the the existing runtime environment.
