I currently have a realm defined: realm liv.ac.uk { type = radius authhost = LOCAL accthost = LOCAL } I now have one of my departments, which for various complex reasons, has been allowed to have its own user accounts. They have the subdomain name "csc.liv.ac.uk". I want to proxy RADIUS to their server. If I add: realm csc.liv.ac.uk { type = radius authhost = server.csc.liv.ac.uk:1812 accthost = server.csc.liv.ac.uk:1813 } Is this position dependant? Does it have to appear before the liv.ac.uk realm to prevent "user@csc.liv.ac.uk" being caught by the first realm? I have: realm suffix { format = suffix delimiter = "@" } in radius.conf. --------------- Barry Dean Networks Team Computing Services Department Tel: 0151 794 5641 (x45641)
