Device Manager is missing.

[GaryK2]

A friend of mind lost her flip phone and I talked her into a new S4 from AT&T. I have a Verizon S3. One of the first things that I wanted to configure was the device manager in case she misplaced the new phone. Under Google settings, there is no Android device manager! I also looked under the regular setting under security, device administrators and there were no entries. On my S3, I have a Android Device Manager check box which I have checked. If I try to find her phone through the web interface, it does not find it. My guess is it would find it because it is not installed. Am I doing something wrong? Is this an AT&T thing?
How do I get this corrected?

It may well be AT&T. On my Verizon S4, in Settings > More > Security, there is a Device administrators section that does include Android Device Manager (along with Email and the dreaded Knox).
