Created attachment 1855 [details] Add certificate support for hostbased authentication It would be extremely useful to be able to use certificates with hostbased authentication in environments such as compute clusters. The attached patch adds this support. If the client has a host certificate, it will be used for hostbased authentication. The server will use any applicable @cert-authority entry in the ssh_known_hosts file to validate the cert.
Patch applied (with a small tweak). This will be in the soon-to-be-released OpenSSH 5.6.
With the release of OpenSSH 5.6p1 this bug is now considered closed. If you have further problems please reopen or file a new bug as appropriate.
