IP Address not visible in netlogin session

Why is the IP Address not visible in the netlogin session under the port command? I found this article but it doesn't really explain what needs to be done to get this working. I am indeed using policy mode.

Sorry to bring up an old post, but your post is a top hit on a Google search. I'm also seeing the same thing but not on every switch. I'll use this command to get a summary of connected hosts:
show netlogin dot1x detail | i host/

I have 3 switches configured for 802.1x with connectivity to 3 Windows NPS Radius servers. The Radius is looking for a certificate which is autoenrolled on domain join. This all works but only 1 of my 3 switches shows IP addresses, and two other switches just show 0.0.0.0 as the IP address. The machines are authenticated sucessfully and are pingable. I can even ping them by name on the switch itself, but when I re-run the command it still shows 0.0.0.0, so the ping did not "learn it" in the output of show netlogin dot1x detail.

All three switches are: 5520-48W 32.7.2.19 patch1-32.

About to roll this out to more switches so I'll see which ones are lucky enough to show the IP address or if my one switch stack is just a lucky oddball.
