On one server, but not in one instance.
I'm using in-kernel capabilities of latest Linux kernels to create separate
instances for DC and other daemons.

Intel Atom, 1Gb RAM, DC and MySQL server in separate containers.
Host itself runs a fileserver as a member server.
8 to 16 users, high traffic spikes (users work with large documents stored on
network shares).
Only issues so far are the user mapping management and new share creation on
member server. I can't get the rights management straight yet.
