Hi All, I'm trying to implement SER into an existing system, and having problems with radius authentication. RTFM and lots of google hasnt helped! The existing working freeradius server uses Unix (/etc/passwd) file (on FreeBSD) to authenticate users who dial into a modem server. I'd like to use the same accounts and passwords for SIP users, using the same radius server. I'm using the default modparam values for module auth_radius. However, the doco suggests to me that I have to use Digest authentication when I call radius_www_authorize. But the cleartext password is not available to the Radius server(ie I'm not using entries in the radius "users" file) so I cant see how it could do Digest authentication at its end. The existing authentication uses Auth Type := System. So, can I get SER to do cleartext auth to the radius server (both are on the same, isolated subnet, so I'm not worried about traffic being captured) Is there a service_type or something else? Any advice appreciated Steve
