I first ran into this because I was experiencing the issue described at this post: forum.civicrm.org/index.php?topic=6090.0
I'm getting an error when I use the simple curl request script " Connected to example.org (xxx.xxx.xxx.xxx) port 443 (#0) * Initializing NSS with certpath: sql:/etc/pki/nssdb * skipping SSL peer certificate verification * NSS: client certificate not found (nickname not specified) * NSS error -12227 (SSL_ERROR_HANDSHAKE_FAILURE_ALERT)
So, does CiviCRM rely on NSS for a client PKI cert (our server verifies client certificates before allowing access)?
Thanks!
