---|---|---|
1 | Login Success | A Login Success event reports that the adjacent broker login process has finished successfully. |

4 | Negotiate Failure | A Negotiate Failure event reports that the local broker and the remote broker support mutually exclusive levels of authentication. |
5 | Authentication Failure | An Authentication Failure event reports that Service Broker cannot perform authentication for the connection due to an error.
