Fallback method of authentication
Hi everybody; I have installed FreeRADIUS Version 3.0.7 from source and it's doing machine authentication on a Windows domain. The radius server is a samba member. The place doesn't have a DC, so, the radius authentication is done to a remote DC. If the WAN link to the DC site fails, machine authentication on the Freradius server will fail. Because of that , I'm considering having a fallback method for authentication (files) when the link goes down. Is that possible to implement via the configuration files? Could somebody give me hints to achieve that. Thanks very much for the help. Rafael

That makes it more difficult.

There is no real way to do fallback authentication. Because EAP / machine authentication is designed to make that impossible. Put a backup DC in the local site. That's really the best way to solve the problem. Alan DeKok.
Hi; Thanks, Alan. Actually I wouldn't want to spend more resources "just" for a DC. If possible, I would keep my Ubuntu samba member server only. What if I use LDAP instead of EAP? Would it be possible to do this fallback?

Do you want your users to be authenticated? If so, install a local DC.

No. LDAP is a database. EAP is an authentication method. Host authentication uses EAP. And the host credentials aren't available via LDAP. Alan DeKok.
