Hi Alan/Ivan: Thanks for your useful posts on this mailing list so I could configured all basic stuff to work finally(though it's still a little challenging for me as a beginner) . Now two more specific problems would like to get your further help/guide: 1. How could I get a username/password authenticated against ldap without its realm if there is one(i.e. cut away the realm @something.ca)? I used Freeradius 2.0.5. We need this to see if: * A user is a home user and log in from home NAS/AP (in this case he may not use any realm at all) * or a user is a home user but log in from other colleage/university and proxied home by our upper eduroam proxy server at the guest college/university * or a user is a roaming user from other college/university and we need to proxy the request to the upper eduroam radius server and finally back to his home college/university for authenticating. 2. How could I get the client IP addresses to fill the "framedipaddress" field in the table raddacc? I used mysql as my accounting DB and the client ip addresses assigned by a dhcp server sitting in the LAN/VLAN. Now the field "framedipaddress" or "client-ip_address" is empty. Thank you in advance for your great help! -- Andy An Junior Programmer Information Technology Services Emily Carr University of Art and Design Tel: 604-630-4556 Fax: 604-844-3801 SB Room 341
