Thanks for your insight, you are absolutely correct regarding the issues.
I will have to find a compromise that is acceptable by everyone.

Only that the FR site mentioned it to be complicated and we already have an
NPS that we are otherwise happy with.
Looks like this would be the best option.

Will definitely look into that.
The difficulty is that some of the users are so remote from us that our
only encounter with them is seeing a log entry.
This is a global solution very removed from the local tech team, only used
to let roaming users on the wireless network.
We are providing a radius so they don't have to maintain a full copy of all
the users in the network (network of companies).
It's a continuous headache for us.
