3.1.3 Initialization

The client creates an RPC association (or binding) to the server RPC endpoint (as specified in section 2.1) when an RPC method is called. The client SHOULD create a separate association for each method invocation, or it MAY reuse an association for multiple invocations.

The client SHOULD create an authenticated RPC association with the highest possible authentication level. RPC authentication levels are as specified in [MS-RPCE].<3> Because the RPC server endpoint is dynamic, the client MUST use the RPC endpoint mapper services (as specified in [MS-RPCE] section 2.2.1.2) to locate the endpoint at which the server is registered.
