Need help reg free radius server

Hi, I am new to free radius server. I installed Radius server on my Linux platform. It is authenticating the user name and password successfully. But when I add the vendor specific attributes, it is not sending those attributes to the Radius server so that I am not able to login to the box. I added these attributes in the dictionary and user files successfully. Still, I could not able to make it. Can you tell me the reason why it is not happening with attributes. Thanks in advance... -- Thanks, Balajee
