Demonstrate the problem of no service management

Without this patch the LDAP service is not configured in the ldap
container.  This patch addresses the problem by adding the same Puppet
configuration from the shared VM to the ldap node classification.

This patch demonstrates the issue of no service management when the
docker container is being built.  There are basic operations, like
adding files, and running simple commands, but the overall task of
starting the LDAP service and then loading an initial set of data into
it is problematic in the Docker model of super-lightweight services.

There are two paths forward from here.  The same Puppet code should be
usable with a heavier, but still "light" container that has systemd and
looks more like a full VM or VPS.  The Puppet code could be modified to
work in conjunction with docker to load the data in multiple stages.
