I've scanned the forums, tried everything I could find, plus a few of my own ideas to get a Thawte certificate generated after June 2010 to work on my GWIA. We are on an OES 2 box, patched current, running GW 8.0.1. I used gwcsrgen to generate the csr and the key files.

Web browsers complain when I connect to the gateway (port 9850) as do pop/imap/smtp clients.

When I view the certificate, it shows that it was issued by Thawte and that it is current.

I've tried chaining the Trusted root, Intermediate CA (primary and secondary) and the cert together, all to no avail.

I don't have any hair left from pulling it out.

Do multilevel certs even work in GW8 or am I just spinning my wheels?
