Hi Alan, Michael,
Thank you so much for your reply.
I am still very new to freeradius so correct me if I am wrong. If I am
doing MAC authentication from access points, the chances are the username
will not be available in the request and we would just look into the user
file and see if the MAC address (Calling-Station-Id) is registered or not.
In this scenario, I don't seem to have anything to identify the realm of
the incoming request. This is the reason why I am thinking of using client
section with source IP address mapping with virtual server. I don't really
think this is a good idea as well because we will need to make sure the ip
addresses are not overlapping or incorrectly configured.
Can I do the following things?
1. Create 10,000 virtual servers each maps to a tenant.
2. Create 10,000 client sections with separate ip addresses and associate
them to corresponding virtual server.
3. Create 10,000 realm sections with tenantId and associate them to
corresponding virtual server.
If the radius request is directly sent from access point, use client
section to redirect to the virtual server.
If the radius request is from proxy server, identify the realm with
attribute in the request and redirect to the correct virtual server.
Thank you again for your kind response.
