 The return type of <code>session</code> is <code>IO (Either XmppFailure
-(Session, Maybe AuthFailure))</code>. As <code>XmppFailure</code> is an
+Session)</code>. As <code>XmppFailure</code> is an
 <code>Control.Monad.Error</code> instance, you can utilize the
 <code>ErrorT</code> monad transformer for error handling. A more simple way of
 doing it could be doing something like this:
 
     sess <- case result of
