Yup, the main reason why I wanted to try 2.1.x is because of that (Gpg4Win
uses 2.0.x) Reading your comment gave me a brainwave... It seems that even
though all the keys reside in private-keys-v1.d directory, you still need to
manually add a keygrip to the sshcontrol file for it to be served through

It kind of makes sense, but it's not very well documented (if at all :)

Thank you,
