@skioll FYI: the file you provided has a few issues:

1. It does not include the issuer certificate, e.g. it only includes the signing certificate and it should contain everything but the root certificate.

2. The signing certificate includes a AIA:issuercert reference that points to a non-existent host (http://crl.bjca.org/caissuer).

3. The certificate contains a ldap reference and no http for CRL retrieval; LDAP does not belong on the internet and http is really the only thing you can rely on clients being able to successfully retrieve. This will cause clients problems when trying to validate the certificate also.

4. The AIA:OCSP reference also includes a malformed URL, the OCSP:// url moniker will be HTTP or HTTPS and no clients I am aware of will understand it as specified.

No client that has not been configured to work around these situations will be able to validate this file with this issue.

Lesser critical issues are the key used to sign the document is a RSA 1024 bit key which is broadly considered insecure now and SHA1 was used as the hashing algorithm.

I would contact your CA and ask them to fix the issues in their certificate chain.
