On Mac OS X Server, configure the "opendirectory" module.
Do you mean just enable the module? The module itself says:
# This module is only used when the server is running on the same
# system as OpenDirectory. The configuration of the module is hard-coded
# by Apple, and cannot be changed here.
#
# There are no configuration entries for this module.
#
opendirectory {
}
