Hi There!

I have an intranet application, written in asp.net C#,

users enter the intranet, using their domain, username and password, we use google applications and gmail for our company's email, I have a button that allow user connect to gmail URL, Users use same username and password for their gmail account, how can I write a code to auto login to gmail when their click this button, without asking the username and password.

basically, auto login to their mail,

Thanks in advance,
