Hi Ivan, Thanks a lot for the guidance. I rectified the problem. The debug mode shows that it is receiving the request from the WAN IP of the IP (192.168.104.xxx) , while the NAS-IP appeared to be the its LAN IP (192.168.1.xxx). As a result, Radius Server was trying to send the Access-Challenge to the LAN IP of the Access Point, which was not reachable, hence the problem. However, I stuck up at a later stage. The authentication is happening when the users are defined in the "users" file. Then I conencted the Radius Server to LDAP, which is working only if the "UserPassword" in LDAP is stored in plain-text. But my LDAP server contains all the paswords in md5 encypted format. I could not get a solution for authenticating users when their paswords are stored in MD5. I tried to generate MD5 password from the client machine (which is a windows XP) using a small script in C#, but the MD5 generated passwords from C# differ from those in LDAP ( quite strange !!!) When I supply the MD5 encrypted password (if passwords are encrypted using slappasswd in LDAP server) from the Windows XP client, it works fine. Can somebody help me in getting users authenticated with LDAP if the passwords are in MD5?? I went through a document in the Internet that says EAP does not support MD5 hashes, only EAP-GTC and PAP does. Can someone suggest a solution for getting users authenticated through AP whith their passwords stored in MD5?? Thanks and Regards, SaN
I've been trying to autheticate a Wireless Acess Point through a Radius Server for last 1 month, but things doesn't seem to be working for me. The Radius Server is authenticating when I test it with the radtest command. It also worked for a Cisco 2950 switch. But no luck when I use the Access Point. I have tried 3 different accesspoints, including Linksys, D-Link and the Firepro, but none of them worked.
I do not get any error when I check the radius in debug mode. It says "Sending Access-Challange to ....", but the client doesn't get authenticated. I seriously need help on this.
1. Do I really need certificates for authentication?
Yes. That conversation is EAP-TLS. *You* have selected that authentication method when you were creating the connection.
Is there a way to achieve WPA with UserName and Password, without installing certificates?
Yes. You can do PEAP with usernames and passwords. You might need to install CA certificate if you are signing your own.
2. Should the AP send "User-Password" attribute to the Radius Server?
No.
Or should the Radius Server send an Access-Challange to the AP, and AP does matching and all.
AP does nothing. It jast passes the challenge to the users machine.
