One the client side, you should send a control message with an NNTP control
header.  You'll have to look that up in the NNTP RFC.  You generally only
allow it if they are the From or Sender for the message.

On the client side, it send the Username and Password values anytime is gets
a 450 or 480 response from an NNTP host.  There's no client-side event.

On the server, OnAuth should be fired anytime there's a command handler that
requires it (and that's most of them). See all of the calls to AuthOK in
NNTP Server.

Does your server implement the OnAuth and OnSelectGroup event handlers?  If
you don't have an OnAuth handler, you're telling the server you don't use
session level authentication.  In that case, send back the 450 response code
in OnSelectGroup that indicates authentication is required.
