Just a bit more information... we're using a wildcard cert from ipsCA:
E =
general@ipsca.com
CN = ipsCA CLASEA1 Certification Authority
OU = ipsCA CLASEA1 Certification Authority
O =
general@ipsca.com C.I.F. B-B62210695
O = IPS Certification Authority s.l.
L = Barcelona
ST = Barcelona
C = ES
Could that have anything to do with the SSL breakage?
