(added engine-devel, as this extends to the engine side).

AFAICT, we get auth failure, with no reason.
In order to handle it we can go in to ways (need to decide)-

1. Add the keyboard-interactive auth to Mina SSHD.
There's a guy who added it[a] and we may try and ask for hints from him.
I know that patches are welcomed there as well ;)

2. Try to diagnose the failure we get, or scan Mina's err / debug stream.
I suspect we should be able to see something like:

debug1: Authentications that can continue: password,publickey 
...
debug3: preferred gssapi-with-mic,publickey,keyboard-interactive,password 

So if server does not report 'password' as an option we could give a better
auth-failure message.

It will be nice if someone from our community could pick this up,
and if not this would be a nice feature for one of the coming versions.
