Good to know.

We have full control over the NAS and what it supports.

Excellent - the dictionary part seems straightforward.
What I'm wondering is how to get the group membership from the OS into a
radius packet. Is there some kind of command from unlang that can
execute a shell command? I'm hoping for something along the lines of
"exec mycommand.sh username" that returns an array of variables, in this
case the list of group names.
