OT: Blocking andriod on WLAN - Urgent Help Please

Hi,

I am not an expert on WLANS.
We have a network with 5508 WLC and cisco 12xx AP.
WE are using cisco ACS with aironet authentication.
All laptops should have a certifcate installed to acces the network and we
need to key in our LDAP username password to gain access to the network.

Unfortunately all android and iphones gain access to the network withouth
the certificate. Any bright ideas on how to block to this.

Please help as this is critical. Appreciate your help.
