Hi,

I tried a few OpenShift deployments:

* Master (with Security) and ExampleDS (file system storage)
--> works

* Quickstart branch (no security) and ExampleDS (file system storage)
--> works

* Quickstart branch (no security) and MysqlDS (using the MySQL cartridge)
--> schema errors

===> I fixed that locally, by using the @JoinColumn annotation.
Before sending a PR, I am doing some more tests
