I'll take that back. Having now looked at the PuTTY patch, I see that the
-f flag already does precisely that. The question, then, is whether the
SSPI implementation is doing the right thing. David said that
an empty credential set was being forwarded. Would be nice to know what's
happening on the wire: the client is supposed to ask the KDC for a new
TGT for the target host, prior to the GSSAPI exchange. (Unless perhaps
addressless TGTs are being used.)
