[RADIATOR] Certificate Not Trusted - InCommon? [EXT]

Hi Roberto,

That issuing certificate is an intermediate that is actually signed by:

Issuer: C=US, ST=New Jersey, L=Jersey City, O=The USERTRUST Network, CN=USERTrust RSA Certification Authority

So the USERTrust RSA Certification Authority certificate will be the one that most devices will actually know about by default.

You should send the InCommon RSA Server CA certificate as part of the chain along with your own server certificate.

Hope that helps.
