If a slave host controller fails authentication it just keeps re-trying

If the slave host controller can not connect to the master host controller due to failed authentication the following message is continually logged as it keeps retrying.

"JBREM000200: Remote connection failed: javax.security.sasl.SaslException: No more authentication mechanisms to try"

In general for clients connecting using Remoting and authenticating we probably want something more specific to indicate a failed authentication as retrying is probably never going to work.

The looping here is also bad if a form of brute force defense is added as this may appear as an attack.
