We use freeradius with LDAP authentication for dial-up PPP service. When Win2k/WinXP users get authenticated with LDAP through freeradius, they have problems loading some particular web sites. The webpages cannot be loaded. It returns normal after I stop using freeradius for authentication. Win98/ME users don't have the problem.
I expect that freeradius will only do user authentication and nothing about the user's behaviour after login. I can't imagine how freeradius affects the browser's behaviour after successfully authenticated. Anyone knows any parameter in freeradius that will cause this? Fu - List info/subscribe/unsubscribe?
