The Manager interface represents an authentication
 service. It supports explicit session-based authentication for
 servers that use factory/home interfaces for object creation.
 
The initial object reference for a server's Manager
 object may be obtained from the standard CORBA Naming Service using
 CosNaming::NamingContext::resolve, or may be obtained
 using CORBA::ORB::string_to_object on a stringified IOR.
Create an authenticated session. The lifetime of the session is determined by the server based on available resources and security policies.
    SessionManager::Session createSession
    (
        in string user,
        in string password
    );
Note: the session lifetime is not limited to the duration of the connection (e.g. TCP socket) which was used to create the session.
Ping the manager.
    void ping
    (
    );
