what "different authentication methods"? Did you mean something like
PAP vs EAP? If yes, FR does that automatically.

realms and NAS IP address are also attributes. You can (for example)
select which backend to use (e.g. which sql server, or whether to use
LDAP vs perl) based on certain attributes (including realm and NAS IP
address) using unlang: http://freeradius.org/radiusd/man/unlang.html
