OK, I see what the problem is. If no certificate is exchanged the used
certificate does not end up in the remote auth-cfg in a way currently
used when trying to check the configured identity (hostname here)
against the subjectAlternativeName extension of the certificate (only
received certificates are currently considered there). I changed that
in the local-cert-san-check branch.
As a workaround you could either change the identity the server uses
(leftid) to genesis.denninger.net, or set the server identity in the
client profile to the one the server actually uses, which is currently
the full subject DN of the certificate.
Regards,
Tobias
