Linking an Apple TV through the enterprise wifi

I am trying to create a profile using apple configurator to enable access from my Apple TV to my Meru WLan which is enterprise security. The configurator says in the trust box to set up the certificate on the credentials tab however there is no such thing as a credentials tab in apple configurator there is however one in iphone configuration utility.

Is this just a bit of poor programming and testing or am I missing something here?

Thanks
