Investigating, I found that the GSSAPIKeyExchange support had gone missing, and this is not reported in /usr/ports/UPDATING or elsewhere that I could find. Large sites like ours absolutely depend on this functionality (which also includes rekey-on-ticket-renewal and store-tickets-on-rekey functions to keep long-running sessions authenticated). >How-To-Repeat: Upgrade openssh-portable. Notice that the GSSAPIKeyExchange parameter causes config file parsing to error out. >Fix: RedHat forward-ported the patch from 5.7 to 6.2 and with a few modifications I made theirs work, but I'm not sure what the legal status of this patch is. You can find it by searching for "openssh-6.2p1-gsskex.patch". >Release-Note: >Audit-Trail: >Unformatted:
