Registration of a RHEL system to Red Hat Customer Portal fails with 'Forbidden: Invalid credentials for request' message regardless whether the 'insecure' parameter in rhsm.conf is set to 0 or 1

Solution Verified - Updated -


I have a server behind a company proxy, and I wanted to register this server to the Red Hat Customer Portal using subscription-manager. The company proxy uses a username and password. The company proxy is configured to do SSL Inspection. I entered the proxy data in /etc/rhsm/rhsm.conf, and tried to register the server with 'insecure = 0' in /etc/rhsm/rhsm.conf, and registration failed with this message returned:

Forbidden: Invalid credentials for request.

I then changed the 'insecure' parameter in /etc/rhsm/rhsm.conf to 'insecure = 1', and tried again to register the server, and still the registration fails with the same message returned.
This happened while I can access the Red Hat Customer Portal using the same credentials I used with Subscription Manager.

The registration was only successful after I disabled SSL Inspection on the corporate firewall. However, I would expect the registration in this case would have worked with 'insecure=1' in /etc/rhsm/rhsm.conf, without having to disable SSL Inspection on the corporate firewall.
