I haven't tried the password based authentication with Sierra as I prefer
certificates. But I might think about it if everything else fails.

eap-tls – and it worked fine until I upgraded to Sierra. The first problem
was that the upgrade to Sierra discarded our CA certificate without telling
so. That was big fun. But even after trusting the CA again the connection
didn't work. The connection would be established but not traffic appeared

There are other funny problems of course. Another Sierra based Mac can
connect and routes everything fine but loses its connection every 8 minutes
like described here:


Exactly every 8 minutes. And we have no clue why this is happening.
According to the logs on the server and the client they just disconnect
without any errors. Changing the dpd values had no effect.
