Hi, Veera.
`well-known/openid-configuration` only contains data related to OpenID Connect functionality. User registration is not part of OIDC, but Gluu's own feature.

Could you elaborate? What do you mean by "console"? FYI, you can add users manually by going to "Users -> Manage people" page in oxTrust web UI.
