Hi Ahmet,
The log message gives a very clear indication of what the issue could be. Please see the highlighted portion:
17/08/2016,13:59:01,Authen failed,name_surname,Domain_Users,ec-1f-72-c4-c5-1c,(Default),EAP type not configured,,,1,10.1.10.120,,,,,,WLC_802.1x_Client.
What is the EAP type configured on your device? This does not seem to match what it is configured on the ACS. Please get this rectified and it should work.
Best Regards,
