Fwd: [Bug 1242] GSSAPI Keyexchange support

Just because I know readers of this list have been following the GSSAPI Key Exchange saga over the last 9 years, I thought the following mail from OpenSSH's bug tracking system might be of interest.

I still believe that their argument is bogus, and I will continue to maintain the OpenSSH key exchange patch. As far as I'm aware, RedHat are now the only major vendor who ship OpenSSH without it.

Cheers,

Simon.
