Why openNetworkConfiguration not working in enrolled device?

I have enrolled a device and want to use managed wifi on that device. I have used following configuration-

 "openNetworkConfiguration": {

    "Type": "UnencryptedConfiguration",

    "NetworkConfigurations": [

      {

        "GUID": "inovex_wifi",

        "Name": "INovex-Dev",

        "Type": "WiFi",

        "WiFi": {

          "SSID": "INovex-Dev",

          "Security": "WPA-EAP",

          "EAP": {

            "Outer": "EAP-TLS",

            "Identity": "faruk",

            "DomainSuffixMatch": ["dms.mobi-manager.com"],

            "ServerCARefs": ["ca_inovex"],

            "ClientCertType": "Ref",

            "ClientCertRef": "client_inovex"

          }

        }

      }

    ],

    "Certificates": [

      {

        "GUID": "ca_inovex",

        "Type": "Server",

        "X509": "ca_base64"

      },

      {

        "GUID": "client_inovex",

        "Type": "Client",

        "PKCS12": "client_base64"

      }

    ]

  }

My expection is 

1. This network automatically save in wifi list
2. As I set client and server certificate the device should connect automatically
3. For information I have used freeradius server for authentication.
