Hopefully someone here will be able to help me, as I have been stuck for a few weeks now.
I have followed the white paper on setting up a Forms Server in the DMZ using internal Directory Server. It seems however that our internal server does not want to authenticate my DMZ server. For example; When in /formsConfig#forms if we click 'Test Connection' we get an error that says "The caller was not authenticated by the service.". If I perform a packet capture, I get the message "The request for security token could not be satisfied because authentication failed.". I have confirmed that it is reaching out to internalserver/LicenseManager/service when making the request and not some internal service. I have performed a full uninstall and repeated the steps in the whitepaper for 10+ multiple times.
All ports are currently open for testing, it is not a firewall issue. I feel like I have performed every troubleshooting step I can. The systems are able to fully communicate and I am getting an Active rejection from the LicenseManager.
I should state for clarification that the DMZ server is NOT on the domain. This leads me to believe the problem may lie in the fact that the IIS service is running using local systems that have no authorization on the internal systems, but we do not want to open the DMZ server to the domain controller for obvious reasons.
Has anyone else run into this issue or found a better solution for creating public forms? I'm at my limit.
Thank you very much for any responses/help.
