I tried to set up the management authentication ti use an IAS server.
The IAS server accpet the authentication but the controller does not give me access.
I think it is a privilege problem.
In the message log of the controller i had this :
"Dec 04 17:31:42.326 ews_auth.c:1968 EMWEB-1-LOGIN_FAILED: Login failed. User:testradius. Service-Type is not present or it doesn't allow READ/WRITE permission..."
