Do not depend on MMR plugin - start before MMR plugin
    
    The ipa-winsync plugin needs to start before the MMR plugin, so that it
    can register the API functions.  Also, the slapi-nis schema compat
    plugin creates an entry that looks exactly like the default IPA group
    gidNumber entry, so I added an extra (objectclass=groupOfNames) to the
    filter since the slapi-nis entry doesn't have that.
