If the username, password, authenticationParameters, or ldt are null, then mlreplay uses the corresponding values in the recorded
protocol. If remoteID is null, mlreplay replaces the remote ID with a GUID for the simulated client.
When generated, this callback contains commented out code that you can implement when using a generic username, password,
and remote ID for a replay session. The code creates a username, password, and remote ID of user_simulated client number, pwd_simulated client number, and rid_simulated client number, respectively.
