These guide looks amazing: - https://docs.whmcs.com/WHMCS_OpenID_and_cPanel_Setup_Guide - https://api.docs.cpanel.net/guides/guide-to-external-authentication/guide-to-external-authentication-openid-connect/ First, I would try to consider what kind of protocol I can use to connect my WHM with Gluu Server. Will it be SAML? Will it be OpenID connect. If it's OpenID Connect, above doc is good. I saw some SAML / Shibboleth related doc as well in internet which can be used to create SSO bridge with WHM / cPanel server. I believe these are good start!

Hi, Thanks for the replay, i trying to use OpenID connect. What is "Well Known Config URI " in WHM server. How to configure OpenID connect in gluu server and how to allow particular users to WHM access. https://ibb.co/SJGqtHf

Start reading [this](https://www.gluu.org/docs/gluu-server/4.4/admin-guide/openid-connect/). `Well known configuration` is a metadata link of OpenID connect server which publishes all endpoints. RPs can _fetch_ endpoints or various data from that link. "How to configure OpenID connect" is there in doc as well.
