I know OpenSSH currently supports PKCS11 devices (such as smartcards) for publickey authentication, but I would love to see PKCS11 extended further. It is currently possible to perform PKCS11 certificate authentication, via pam_krb5.so (on Linux at least and likely something similar on other *NIX) which allows smartcard auth to a Kerberos (including AD) server, where a TGT can also be granted. How difficult would it be to add functionality to OpenSSH so that it can funnel PKCS11 certs from SSH client to server and on to PAM where it could be used by Kerberos/PKINIT? My thought is that this is at least part way there with the current PKCS11 support but I won't claim to be an expert regarding the internals of what would be needed. I would think that a number of places using smartcards (I currently work for a gov agency that uses smartcards) would find this approach to have additional security and management features (given real-time validation against a kerberos/AD server) over using publickey auth (based on PKCS11) and also having the added benefit of granting a TGT on sign-in, enabling SSO (GSSAPI) to additional backend servers. What are thoughts on this functionality being added to OpenSSH? Am I the first to suggest such a thing?
