Hello, can I ask you again? I would like do assign some specific roles (view-realm, manage-users) on the client realm-management to a user . Via REST API, I cannot, however, even display the role-mappings by doing HTTP GET on /auth/admin/realms/xxx/users/4c0f445a-53e9-45c2-a9c9-a8ac69bb5b48/role- mappings/clients/realm-management (Gives HTTP 404, xxx is my realm). But, if I take my own client, whose name is web_app, then the request /auth/admin/realms/xxx/users/4c0f445a-53e9-45c2-a9c9-a8ac69bb5b48/role- mappings/clients/web_app works (HTTP 200), giving empty array. When doing this, I follow instructions on https://www.keycloak.org/docs-api/4.0/rest-api/index.html#_client_role_ mappings_resource Can you tell me, what the problem is? Thank you, Venca.
