SAML identity providers integrated with ArcGIS Enterprise can support group membership. Similarly, it would be great to support OIDC backed group membership through calls to a groups or memberOf (etc) property.
@NicolasGIS Thank you for noting that we don't include this information on the documentation page you linked. We will work to update that page to reflect this change.
For your other feedback, if you wouldn't mind creating a dedicated thread that would be great. Thank you!
