Hi, I'm trying to set up a freeradius server to serve two clients, each of them an independent wireless network. The first one uses WPA2-Enterprise, and is expected to authenticate our users based on our internal LDAP server. The second one is a guest/open network, where users will pass their credentials in a captive portal, and are expected to be authenticated by a MySQL database. Problem is, both networks are covering the same area, and users of one of them is not allowed to use the other. I tried to set up radiusd.conf to include the appropriate modules, but I noticed that if the user sends a valid credential in the wrong network, it still gets authenticated. So, how can I enforce that users from NAS-IP-Address 1 get authenticated only by MySQL, and NAS-IP-Address 2 only on LDAP? I'm using FreeRADIUS 1.1.7 on Suse SLES 10 SP4. I have some machines with SLES 11 SP3, which will give me FreeRADIUS 2.1.1, but I prefer not using them by now, for several reasons.
