Oracle EBS SSO with multiple login page

Hi Experts,

In Our Environment Oracle EBS already integrated with OAM access manager. zero sign on is not configured in our Environment.

Now we need configure zero sign on which can be implemented using WNA(windows native authentication). We need some users having respective responsibilities cannot be login using zero sign on.

User name and password prompt for this users. Some users with respective responsibilities must connect using zero sign on. In my case Load Balancer is configured i can have two login URL based on responsibilities.

Can anybody assist me in implementing two login page, One with zero sign on(WNA) which is possible. Other with username and password from OID.
