This particular exception occurs when TMDA (or the tlslite internals) 
attempts to write to a closed connection.

I'm guessing what happens is that the "auth failed" response gets sent 
back to the client, which then disconnects, but the disconnect occurs 
before all the SSL protocol hand-shaking has been transferred, hence the 
exception.
