OCSP Authenticatioin profile error with clients that don't know the certificate issuer?

I do think it has to do with the certification heirarchy and the F5. I am able to see the OCSP query and response when I login from a computer that has the heirarchy. however, when I use an external resource that doesn't have the heirarchy, i don't see the query, like the authentication process breaks down before it gets to the verify part.
