You can force one daemon to start after another one without editing any
of the existing RC scripts (likely to get blown away when you update
that package) by adding an additional RC script like so:

#!/bin/sh
#
# Make isc-dhcpd start after slapd

# PROVIDE: precedence
# REQUIRE: slapd
# BEFORE: isc-dhcpd

Test the resulting startup order by:

  rcorder /etc/rc.d/* /usr/local/etc/rc.d/*

	Cheers,
