This isn't a great fix @MRCUR. For a start, you can't apply the policy until the user has connected (so you can see them).
Next if they connect rarely (say annually to provide support) and they age out, you have to re-apply that policy, but only after they have connected.
The policy needs to be applied at the user level, before they connect.
I tried applying a policy using RADIUS and the Filter-ID attribute (that other bits of Meraki kit use) but alas it ignored it. We really need Filter-Id RADIUS support as well.
