I have been trying to configure OpenAM in my laptop to no success. Here's what I have done.
During initial configuration you should not use external data store, just use embedded one and configure external one later on.
Can not be contacted seems more like a resolver issue ...
Another note as this is the data store you may not use suffix 'dc=openam,dc=forgerock,dc=wipro' .... you are not Forgerock ;-)
