at least for now.
In the long run, we should probably provide some LDAP-solution by default.
therefore, asap LDAP is finished this issue should be removed.
@christoph: since there is a already an branch for this: when can we make use of it?
The branch for OPENENGSB-200 relies on JPA.
The other branches are quite different in architecture and I do not want to merge any of them.
