Hi all,

I installed strongswan 5.2 on Debian wheezy running on a KVM machine.
Strongswan is up and running and can be reached from outside. But there
seems to be something wrong with the certs.

The ca.crt is created including

basicConstraints = critical, CA:true
extendedKeyUsage = serverAuth
keyUsage = critical, keyCertSign, cRLSign

and the server.crt is created including

extendedKeyUsage = serverAuth
subjectAltName = DNS:FQDN removed

The ca.crt is already installed on the lumia and a reboot is performed.

After starting strongswan with --nofork I get following messages:

Any hints what I need to do for correction? I am wondering that strongswan
is loggin "id . . . not confirmed by certificate" while starting and "unable
to resolve %any".

Thanks for your help!
