Gluu server is hosted on a amazon ec2 instance on a private subnet. To expose the openid to internet, we have to use the amazon ELB. I installed a apache2 reverse proxy which will hit the gluu server. But the gluu server returns an href on its response and redirect to the server. hosted gluu server on : gluu-ec2-inst1.amazonaws.com hosted apache server on: gluu-elb-inst.amazonaws.com when I used the gluu-elb-inst.amazonaws.com, the response send to the browser has an redirect url to the gluu-ec2-inst1.amazonaws.com. In the following example from the apache log, there is an redirect uri, which point to the internal server. The internal server will never be reached from the external resource. for apache log: gluu-elb-inst.us-east-1.elb.amazonaws.com:443 3.203.36.5 - - [24/May/2018:05:38:41 +0000] "GET /oxauth/authorize?scope=openid+profile+email+user_name&acr_values=auth_ldap_server&response_type=code&redirect_uri=https%3A%2F%2Fgluu-srv-inst1.us-east-1.elb.amazonaws.com%2Fidentity%2Fauthentication%2Fgetauthcode&state=ad872214-785d-476a-a060-951ed57cfd7a&nonce=f3dfe6ae-a52b-423f-ab49-143e08114ed5&client_id=%40%213A0E.33E6.9C98.680E%210001%214CF6.7B23%210008%21AACB.58DC HTTP/1.1" 302 868 "-" " So my question is , how to solve this issue?
