Has anyone been able to successfully use this feature? My freeradius setup looks like this:
xxxx Cleartext-Password := "xxx"
Fall-Through = No,
cisco-avpair = "url-redirect=http://mrtg.uio.no"
The Radius part seems to be working, once I've authenticated with 802.1X and open Firefox I'm redirected to http://$url-from-radius/?switch_url=https://$ip-address-on-virtual-interface... My browser is then redirected to a new url, which is the old url concatenated with "http://$url-from-radius/?switch_url=https://$ip-address-on-virtual-interface..". After some time the redirection stops, the URL is then some 900 characters in length - looks like Firefox gives up. I've tried with Opera and Internet Explorer as well, the problems are somewhat similar.
Thanks for any tips/hints.
