Hello, Currently OpenSSH has a fixed order on how the key authenticates the user: at first it tries to authenticate against TrustedUserCAKeys, afterwards it does it against the output keys from the AuthorizedKeysCommand and finally against the files as set in AuthorizedKeysFile. I have an use-case where this order is not ideal. This is because in my case the command fetches keys from the cloud

How reasonable, acceptable and difficult would it be to "enhance" openssh so authorizations using kerberos (specifically kerberos tickets) consulted the authorized_keys file? And to be a bit more precise... consulted authorized_keys so it could utilize any "options" (eg. from=, command=, environment=, etc) that may be present? I'm willing to make custom changes, but

...s2 file entries can. So, after looking around, especially in key.h and key.c and auth2.c, it occurred to me that a new key type could be added for dealing with named keys, that is, names which can be authenticated (e.g., certificate names, Kerberos principal names). The neat thing is that auth2.c:user_key_allowed() is key-type independent (so arguably it doesn't belong in auth2.c), and thus could be called from ssh_gssapi_userok() [instead of, or in addition to the GSS mechanism specific *userok() methods]. The only questions, in my mind, are - how to format key names for use in authorized_keys2?...

...ct to localhost. When prompted for the public key passphrase, press Enter; then enter your normal password when prompted to do so. Observe that "hello" is printed and no shell is given. I believe that the problem here is that, if authentication fails after calling auth_rsa_key_allowed or user_key_allowed in the privileged process, authentication options are only cleared in the monitor rather than in the privileged process. The obvious fix seems to be to clear them in both processes. This is implemented by the attached patch. This is only reproducible if the last key offered by the client is the on...
