DLU not being applied

Hi Folks,

I have a ZCM 11 server on which I'm attempting to dole out a DLU policy (all my other policies reach the desktops). No matter what I do to the policy it does not appear on the Win7 client I'm testing it on. When I ramp the logging up to debug, I find the following in my log:

So clearly the policy is being filtered by UserPostdesktop (whatever that is).

How can I go about determining why this policy is being filtered?

Thanks,
