Hi Aliaksandr / Michael .
Thanks a lot for your response and support.
I have installed and configured plugin for Moodle OIDC, following the link that you sent me, but still I cannot able to establish session with Gluu Server.
I have added manually the client to Gluu Server without problems, according OIDC moodle installation.
Also I have readed this link: [https://support.gluu.org/single-sign-on/6364/single-sign-on-sso-to-moodle-353-with-openid-connect-oidc-is-displaying-json-instead-of-login-form/], but also it's not working
I have on question: Where are the options for Authorization Endpoint and Token Endpoint in Gluu Server ? I don't see this directories in server.
Also I don't see requests from client to server. What log file do I need to check?
Please could you help me? I have configured wordpress without problems, but Moodle it's not easy.
Please, if you need any additional information from me, let me know. I am working with an interesting project, and only we need configure moodle's authentication.
Thanks in advance.
