Hello,

I'm actually trying to setup a SSL reverse-proxy based on Apache 2.x and
mod_ssl and it seems there's a bug in the verification of the CRL.

If a CA changes its keys before expiration, the CRL is now signed by the
new key and include certificates issued by both the new and old keys.
However, mod_ssl will refuse to work if the AKID of the revoked
certificate doesn't match the issuer of the CRL.

Browsing Apache archives, I found that somebody posted a patch covering this need (http://marc.info/?l=apache-httpd-dev&m=120350484626015), but
the code haven't been merged. I tested it and it works perfectly well.

Does this patch seems OK to you ? If yes, is it possible to include it ?

I just tried that patch - and it also matched two of my edge cases.

But this is a bit too obscure for me to dare to commit it directly. Could someone else with a good x509 understanding look at it ?

+1 from me - willing to do the legwork if someone else gives this a good review as well.
