Windows login username required at server end

Hello,

I have a requirement wherein I need the windows login username in my application on JBoss.

I have been investigating using the JCIFS library but so far whatever I do, JCIFS tries to authenticate the user with the domain controller.

What I need is not authentication with the domain controller. I just need access to the username with which the user has logged in to the windows machine.

My application assumes that if the user has successfully logged in, he is a valid user.

Can JCIFS help me with my requirement?

If not, does anyone know how I may be able to achieve this? Any help in this regard is highly appreciated.

Thanking everyone in advance,

Abhi
