Putty Psftp: keyboard-interactive login is supported?

[Chet Vora]

Hi all

I'm trying to use psftp with our server using keyboard-interactive
authentication. However, it seems that it attempts to always use
password method if available even when the server sends back keyboard-
interactive as one of the allowable methods. I could be wrong but I
thought kb-int was supported by psftp.

As a quick test, I made the server send back just public_key and
keyboard-interactive as allowable methods and it send back an error
saying not supported auth methods were found. Here is the log:
-------------------------------------------------------------------------------

I can do this with no problem. One thought: in the PuTTY GUI, there is a
check box for keyboard-interactive under Connection->SSH->Auth; make sure
that's turned on in the default settings.

Sorry if I wasn't clear in my earlier post but I could do this with
putty, its psftp that I was having problem with. psftp by default
doesn't use keyboard-interactive but password authentication. Maybe
this is because my putty default settings don't use keyboard-
interactive authentication. Well, I figured a workaround. I can use
the -load <sessionname> option to load a putty kb-int session and this
works.

Thanks.
