Hi folks,

Thanks for the feedback, I already tried the AuthenticationMethods
"publickey,publickey" but is there any tool allowing this kind of
connection from two clients to the server in the same time using
ssh-Key cause it's not possible using putty ..
No, as I said, it is not designed in the SSH protocol

P.S. Answer to the list, not personally.

to authenticate to server X : I need two people A and (B or C) together.

anyone seen this or know how to do?

I know there is key + password (which is kind of this direction) but
not exactly what I'm looking for...
You can use the very same directive AuthenticationMethods to ask for
multiple keys too.

  AuthenticationMethods "publickey,publickey,publickey"

would require three different public keys to authenticate.

However, there is nothing in SSH protocol that would enforce different
people to be involved at the client side.
