Neha,
I think that in this case, based on the nature and complexity of the issue, this would be better dealt with as a formal support request. I recommend opening a support ticket and providing the following information:
Environment Details:
* Policy Server/Fed Manager/Secure Proxy Server/Web Agent versions
* Operating System
Logs:
* Header trace (Fiddler/HttpWatch) showing the behavior
* WebAgent trace log
* Policy Server trace log
* FWSTrace log (if applicable)
* WebLogic logs
This will help us determine exactly where the problem lies and allow us to give you a way to move forward with your workflow.
