Depends on how you setup your cluster, but based on earlier posts here is suspect:
http://amdhandev.amdhan.local:50200/esourcing/fsbuyer/portal/login?cid=cluster.amdhan
typically the ?cid=cluster.amdhan at the end can be left off. So this should work as well...
http://amdhandev.amdhan.local:50200/esourcing/fsbuyer/portal/login
if you are using the Netweaver UME as the user store you will get a Netweaver login screen.
