eMake to agent communications require agreement on security settings. If authentication is disabled on the agent, then it will reject requests to authenticate.
Security Exposure: This message only issues from agents that do not require authentication. Instead of attempting to trigger this message, an attacker could simply exploit the insecure agent, and the success of that attempt would provide the information that this message would have provided. Therefore this message does not provide any information that an attacker could not get another way.
