I want a condition match on this type of object in AD.
Basically any 'computer'.
As per screenshot below.

I presume this query/filter and attribute is what matches the 'name' column of all these computers is 'dNSHostName' ?

I just need logic to say 'if I see a computer object in AD'...
Aka,
'Authorization: AD' + 'HostName' (alias in CP) = EXISTS ?
