Pending OpenSSH release: contains Kerberos/GSSAPI changes

[Wachdorf, Daniel R]

No.

1 - RFC states GSS_C_MUTUAL_FLAG SHOULD not be used.  The current open ssh
server requires that it be used.

2 - RFC also allow for gss mechanisms that don't have GSSAPI integrity.
Servers can then choose to disallow it. As far as I can tell from the code,
any client which doesn't (or cant) have the GSS_C_INTEG_FLAG set cannot
connect.  I can't test this because Kerberos-gssapi uses integrity.

This right here is the key to me.  If someone is not following the RFC.
Then I say let them complaint to their vendor.

Again I ask.. As the code stands are *WE* in RFC compliance?  If not we
need it fixed.

As for what to base it off of.  Pick a recent snapshot.  Not as if the
GSSAPI-WITH-MIC code has drasticly changed in the last few days.
