Re: [Handle-info] Authentication using existing client certificates
That's correct. The handle server uses the client side certificate as a way to associate a handle identity and public key with the client. The handle identity is encoded into the UID component of the certificate subject, although if there is no UID component, the CN component could be used instead. As usual for handle server authentication, the handle identity should refer to an HS_PUBKEY value in a handle record, where the public key must match the public key in the certificate.

Is my understanding correct, that the handle server always uses the given UID information (index of public key or certificate entry:prefix/suffix) to look up the public key or certificate and to check if the public key or certificate referenced by the UID matches the provided private key?

Our existing client certificates contain CN in the form of /CN=Firstname Lastname (space between firstname and lastname!). UID is not used. How can we achieve that we can authenticate on the web interface of the handle server using these as client certificates?
