UserProvider with Local Tomcat 7 Instance - Configuration?

I have created an Olingo application that successfully uses com.sap.security.um.user.UserProvider.  It's working great as an HCP application, but I am having trouble deploying the same application on a local instance of a SAP Tomcat 7 server from Eclipse.

I set the application up based on these HCP instructions:

https://help.hana.ondemand.com/help/frameset.htm?9e2e0d7e91cc44e79901a756bf7b2d88.html

The error report from the local Tomcat logs is:

#dev_default#javax.naming.NameNotFoundException: Name [user/Provider] is not bound in this Context. Unable to find [user].|

I have tried this with the "Enable Security" flag on and off -- same result.

The documentation seems to indicate this should work.  Is there a magic passage I need to add to my context.xml -- or elsewehere?

Thanks,

Riley
