  OK... I assume there are actual RADIUS attributes for this?

  They're certainly not standard attributes.  Maybe Mikrotik has such attributes, but I don't use Mikrotik, so I'm not familiar with them.

  That explanation makes a lot more sense than the previous very vague question.  Details matter.  And giving details helps us give you the correct solution.

  Which here is (as always): run the server in debug mode.

  See which attributes come in the packet.  Then, write if / then / else rules to match attributes.  And to reply with more attributes.

  See the Mikrotik documentation and/or dictionaries for which attributes need to be in the reply.

  See the FreeRADIUS documentation for how to configure FreeRADIUS.

  There are 1000 vendors, each of which have 1000 different products.  We can't document them all, unfortunately.
