What is resource_url in OAM

Hi,

We have an issue for one of our portals - our background is for the web application and no knowledge about IDM / OAM - however we have configured the Webgate Agents provided by IDM team into our HTTP Servers.

When user tries to access our application using the URL (example) portal.domain.com/MyPortal, the user is redirected to a custom ADF application that handles the login against our LDAP.

When user puts user name and password, the screen blinks and user is kind of shown the same page (signin.domain.com/Signin) instead  redirect to the home page after successful authentication. I can confirm that the user is already logged in because if the user tries to access again portal.domain.com/MyPortal he goes straight away to the home page.
