Login failure BRMS 6.0

I have a domain controller (JBoss EAP 6.2) running on a separate box to the BRMS host server (JBoss EAP 6.2). I created a user with admin,analyst role by running add_user.sh in the domain controller server and deployed the business-central.war file from the management console. When i try to login on the BRMS console, the login fails. I get a "login failed: Invalid UserName or Password" message.

what could be the issue? Is there a way to enable more logs to understand the issue? or should the users and roles file on the host controller also needs to be updated to validate the credentials?

Please let me know.

thanks,
Vijay
