Hi Valentino, I do not know how to re-open ticket #3628 so I continue here:) You said: > Have you tried looking into SCIM-Client and see how it is doing it? UmaScim2ClientImpl.java Get Scim2Client Unit test I have read the code and cannot see that anything would be wrong with my https requests. It must be the server config. Michael advised: > Can you check the client that is calling the SCIM endpoint, and make sure it has the scim_access scope No the registered client has only scope uma_authorization I cannot add scim_access because the 'Add Scope' dialog does not show such a scope to pick. What can I do about the client configuration (gluu 2.4.4 SP1) ? Regards Ernst
