|For reasons of my own, I rather wait for 0.1.36 instead of patching
|0.l.35. If you roll out 0.1.35, if it is possible, may I request that
|the default PreferredAuthentications be set to
|"publickey,keyboard-interactive,password" instead of
|""gssapi-with-mic,publickey,keyboard-interactive,password"? That would
|help remove the annoying messages in stderr.
As for that annoying messages in stderr, may I ask you to try following
patch?
