Which two elements are required for a Notes client to successfully authenticate to a Domino...

Notes authentication is a "challenge-response" process that requires two primary components. First, the user must have an ID file containing their private key to sign the authentication request. Second, the server must have a matching user name in the Domino Directory (names.nsf) that contains the user's corresponding public key to verify the signature. Without both pieces, the secure handshake between the client and server cannot be completed.
