OAM redirection for protected resource

Hi OAM Community team,

I have IAM-11.1.2.2/IDM 11.1.1.7.0 installed on windows 2008 R2 server. I configured a application domain FMWAdmin and configured a sample protected resource /test2.html. I hit the url

http://pocschedule.abc.org/test2.html

and it gets redirected to  IDM url http://idmpoc.abc.org/oam/server/obrareq.cgi?encquery%3D5k%2Fu

and then the OAM authentication form is supplied. I am able to authenticate and get authorised by IDM properly. However, I wanted to change the URL from idmpoc.abc.org to pocschedule.abc.org when the login form is displayed.

I feel this should be a configuration issue, Can you please guide me.
