Cannot authenticate user using SeaMonkey browser

[Ronald Dai]

Hi, Everyone

I have set up a CAS server, which authenticates the user with NTLM protocol..

when accessed the CAS login url using SeaMonkey, the CAS server returned a HTTP 200 packet.
30 2.143730   152.62.40.246   10.32.97.249    HTTP   GET 
/cas/login HTTP/1.1 
33 2.278017   10.32.97.249    152.62.40.246   HTTP   
HTTP/1.1 200 OK  (text/html)
 
But using IE, the CAS server returned a HTTP 401 
packet.
30 2.763472    152.62.40.246  10.32.97.249    HTTP GET 
/cas/login HTTP/1.1 
33 2.875421    10.32.97.249    152.62.40.246  HTTP HTTP/1.1 401 Unauthorized  
(text/html)

Could you give me some advices on this issue?

Thank you in advance.
