Simultaneous-Use unreliable for 'other' NAS-type

this doesn't answer my question though of how/if checkrad works for
simultaneous-use set to anything other than 1.

Also, could you please expand on what you consider to be 'modern'
NASes? 2 years-old, 5 years-old, 10?

We are looking to replace our crappy HP controller. Unfortunately HP
was taken over by Aruba, and their controllers don't support HP Access
points. So we are trying to go with the latest HP controller, and I
would like to make sure that simultaneous-use will be covered.
