HI, I solved my own problem and thought someone else might like the solution. As I followed the Novell Freeradius integration notes, I had check items disabled. If I enabled this, and modified the ldap.attrmap to suit just those elements I want to check, if the user does not exist, the matching process fails, thus returning a reject. This has added benefit when we use the Client-Calling-ID which is the MAC address of the client. As we record these anyway for a matching 802.1x certificate, we can now make certain that our students don't pass around the certificates as a mismatching MAC address and certificate will now also fail.

Hi,
I'm using freeradius on a SUSE 10 server. I'm using it to authenticate WPA2 wireless clients to Novell eDirectory. There is a twofold process. Being a school security is quite an issue. Each student is issued with a certificate that is used to authenticate him to the radius server. The certificate name is his MAC address. A corresponding NDS account exists for this MAC address. So, if the student installs his certificate and has an account in NDS, he is authenticated and the wireless access point allows an IP address to be obtained and the student has access. Using the NDS account I can limit the students access by changing the parameters of his MAC account. ie, allowed times. THIS IS ALL WORKING WELL. However, I have found a flaw I can't seem to find an answer for. I'm hoping someone can help. If the NDS account does not exist, as long as the SSL certificate is not revoked and is in the Freeradius database, the student will gain access. The radius server, does a lookup, can't find the account and just continues on. I need the radius server to reject access is an missing attribute causing a rejection if the account can't be found. Can anyone tell me how I can do this?
