# Unix SMB/CIFS implementation.
# A command to compare differences of objects and attributes between
# two LDAP servers both running at the same time. It generally compares
# one of the three pratitions DOMAIN, CONFIGURATION or SCHEMA. Users
# that have to be provided sheould be able to read objects in any of the
# above partitions.
