Re: Add Subject Here

Hi Robert

It looks like there’s a missing intermediate certificate (InCommon RSA Server CA) in the certificate chain of et.engr.iupui.edu:

Missing intermediates often cause problems:

Other universities using InCommon certificates recommend sending the intermediate certificate in responses:

Best Regards
Mark
