How to get system user credentials from browser in java over a network ?

[nedumangad chandra]

Hi,
My system is in a LAN network.Whenever a user accesses a website using internet,our network service group authenticates the user using a proxy server.So we can use CAS server in internal applications for implementing SSO(Single Sign On) and authentication. My question is how can we get the system user name from the browser request to my application (which is developed in java and deployed in tomcat)..I know that CAS server authenticates the user with user name and password, from the browser request.But how it is taking the user name (I dont need password and I dont want to authenticate..just user name ..tats enuf i need) from browser..?? Please help..If I missed something,please let me know...

Download and try this out to see if it works.

I'm not familiar with CAS but the source code in the .zip file relies on standard Java APIs.

Good luck!
