Single Sign on using ADFS

Summary

User forced to click on Sign In button

Content

Hi,

We have a client who will be authenticated against ADFS once they enter their user id and Password on their Company portal. Now they have a link to Fusion applications on their portal. After clicking on the link, its is taking them to Fusion login page where he has to click on Sign in button to login to the fusion application (although they do not enter user name and password again). We do not want the user to click on Sign in and instead it should take them directly to the application. How can we achieve that? Any inputs are
