This is a short question, which I'm sure has a long answer..... its something I've come across quite often and but I'm not really sure on the answer.
What's the advantage of using a separate RADIUS server, opposed to just using NAC itself?Sure the answer might be better integration with AD, if say using windows RADIUS, but what exactly does that mean and how does it benefit or not the different types of authentication you might use. Like using NAC for 802.1x via LDAP vs using RADIUS (as one example).
Its simply (as of yet), not seen anything I couldn't do with NAC itself that a separate RADIUS would offer any additional benefit !?
Many thanks in advance.
