Not directly related to openbao, but I've thought about this for awhile that I'd like to use ssh certificates instead of ssh keys to allow an agent a time limited SSH access to a server, and that seems to work for gating the initial connection, but I haven't yet figured out how to enforce the established connection dies after a certain time. I could maybe hand roll a solution with ExposeAuthInfo and ForceCommand wrapper, but it feels like this sort of thing should be handled delicately..
