GoDaddy SSL Certificate Issues With Safari

We just got a new SSL certificate from GoDaddy. And, while all browsers are fine with the certificate, Safari gives the following error:

This certificate was signed by an unknown authority.

We are using a chain file in the following config in Apache:

SSLEngine on
SSLCertificateFile /etc/apache2/ssl/godaddy.crt
SSLCertificateKeyFile /etc/apache2/ssl/godaddy.key
SSLCertificateChainFile /etc/apache2/ssl/gd_bundle2.crt

Looking around the web, it seems that others have experienced this issue as well (http://blog.boxedice.com/2009/05/11/godaddy-ssl-certificates-and-cannot-verify-identity-on-macsafari/) But no solution seems to fix the issue.

Does anyone know why this would be caused, or have experience with this happening, and how to fix it?

Verify that the correct intermediate certificates are being given out by the server at http://www.sslshopper.com/ssl-checker.html

As martona suggested, you may need to use a different bundle.

You may be using the wrong cert chain. I assume your "gd_bundle2.crt" is the same as "gd_bundle.crt" on this page: https://certs.godaddy.com/anonymous/repository.seam

That gd_bundle.crt chain has a "Go Daddy Class 2 Certification Authority" that verifies up to a Valicert root. I don't think this is valid anymore - GoDaddy seems to issue certs that are signed by "Go Daddy Secure Certification Authority" that is in turn signed by a different, self-signed "Go Daddy Class 2 Certification Authority" - not the Valicert-issued one in your chain, so it has nothing to do with your actual certificate.

Go to the page referenced above, download "gd-class2-root.crt" then download "gd_intermediate.crt". Concatenate the two files (they're just plain text files) into "mybundle.crt" and specify this new file in SSLCertificateChainFile. See if that makes a difference.
