I have 2 additional question here (hope you don't mind):

Even if Strongswan ignores the additional certs, is it possible that
some crypto implementation *used* by Strongswan does not, but reads
all certificates found in the cert files (in /etc/ipsec.d)?

Does Strongswan send just the first certificates it has read to the
peer, or does it send the whole certificate file (the chain)?

Reason for asking is that I see some weird authentication failures if
I cut off the additional certificates from the chain files and put
them into seperate files.
