I'm attempting to migrate a RADIUS service from Interlink RADIUS to FreeRADIUS

Good choice. Interlink went bankrupt a few years ago. The current version of the company is selling the old product, and not doing much else.

and am running into a bit of a problem I was hoping you could help out with. Basically, I have several different domains which would all be separated by an @ sign plus the name of the domain. What I'd like to do is use separate local "users" files for each of these domains. Each "users.domain.com" file would then contain the username and password for every user in that domain such that if joesmith@domain1.com logs in, he will be authenticated with the "joesmith" password contained in "users.domain1.com".

To be honest, if all you need is username/password authentication, I would suggest using a real database. It's ever so much easier than poking at text files.

However, there is no authfile in FreeRADIUS so the question is: How do I accomplish this same task with FreeRADIUS? Any information would be greatly appreciated. Thanks in advance.

It can be done, but it's a lot more complicated. You can get equivalent functionality by having the main "users" file do "$INCLUDE" of sub-files for each domain. The domain-specific "users" file would then list: user@foo.domain Cleartext-Password := "password" i.e. Don't strip off the domain, and everything should Just Work. If it doesn't, try: user Realm == "foo.domain", Cleartext-Password := "password" One of the two will work, depending on your local configuration. It's a little more complicated than what you have now, but it's similar enough to be not a large leap.
