Hi,
sorry, but I have not found any documentation on this:

I see that I can add a CA certificate to  TLS_TRUSTCERTS and then set
TLS_VERIFYPEER to PEER to enable certificate authentication.

But with just that setup, if one client key is compromised, I have to
change the complete CA. Is there a way to revoke a single certificate?

I wouldn't mind to copy a revocation list to my server for this.
The only other way I'm seeing is to use one CA per certificate ant that
kind of defeats the purpose.

Thank you,
Lenz Weber

PS: postfix seems to do it the other way round: they require a list of
"accepted" client fingerprints. While that is suboptimal, too, it would
be a solution that I can live with as I have a postfix/maildrop/courier
setup and thus would have to maintain that list anyways.
