i will setting up strongswan and have some trouble with configure it. I can log in with user/pass but i will replace it with user.p12 certificate. When i add rightauth2=pubkey is login with user/pass no more working auth with user.p12 is no working.

my may wo create all certs:

  • If you want to use a different authentication method, change your config accordingly (i.e. set rightauth to pubkey or eap-tls depending on how you configured the client). – ecdsa Apr 26 '18 at 10:41
  • i habe change right auth to pubkey but cannot connect i append my question with log for this. – Hannes Peter Apr 26 '18 at 11:13
  • The log tells you: The client wants to do EAP authentication, while you now configured pubkey authentication. If you configured certificates on the client it might expects the server to initiate EAP-TLS (but macOS should also be able to use simple certificate authentication, but you have to configure it accordingly). So either change the server or client config so they match. – ecdsa Apr 26 '18 at 18:28
