You can execute an RPC for the server that is protected by the OpenTP1 security service. When executing the RPC, check to see if the user authenticated by the user authentication function has the right to request the service.

Using the authentication RPC function requires more memory to execute the CUP. When the memory usage is limited for CUP execution, or the RPC is executed for a server not protected by the security service, disabling the authentication RPC increases the free memory size. Specify DCCLTSECURITY in the client environment definition not to use the authentication RPC.

The authentication RPC function is unavailable if no security function is installed on TP1/Server that authenticated the user. No extra area is allocated in memory. You need not explicitly disable the use of the authentication RPC.
