hi everyone, I will try to explain my problem, in case of LTSP, if the server has access to internet all the clients also have access to internet. But my problem is i have to give access to only authorized person on the client to access net. so need some authentication system. At present we use non ltsp system which uses ntlm and proxy authentication. i cant use mac authentication, coz deployment site has cyber cafe kind of environment, i which user keep on changing but the machines r fixed. I am really stuck coz of this problem, it would be really nice of u if u let me know how to overcome this problem or direct me to other sites tht can help. best regards yogesh
