Greetings, I'm attempting to migrate a RADIUS service from Interlink RADIUS to FreeRADIUS 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. In Interlink RADIUS, I simply use the "authfile" as the "glue" to make this work. e.g. domain1.com FILE users.domain1.com domain2.com FILE users.domain2.com domain3.com FILE users.domain3.com 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". 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.
