Thanks for respining. However, I am sorry, but it still doesn't work.
Problems encountered:

 1/ The /etc/openldap/slapd.conf file doesn't exist. This happens when
    you build with BR2_PACKAGE_OPENLDAP_CLIENTS disabled. I think I
    already mentioned this problem in a previous review of this patch.
    I fixed this problem by doing:

diff --git a/package/openldap/openldap.mk b/package/openldap/openldap.mk
index 18509cc..fdf8c88 100644

 2/ The /etc/openldap/slapd.conf file has permissions that do not allow
    the slapd daemon to read it. I fixed this problem by:

diff --git a/package/openldap/S75slapd b/package/openldap/S75slapd

         printf "Starting $DESC: $NAME: "
         start-stop-daemon -S -q -p $PIDFILE -x $DAEMON -- $ARGS

 3/ The sldap daemon doesn't start because it tries to write its PID
    file to /var/run/, where it doesn't have write permissions, while it
    should create it in /var/run/openldap. Here is the message I get in
    the logs:

Jan 20 22:55:48 buildroot local4.debug slapd[728]: unable to open pid file "/var/run/slapd.pid": 13 (Permission denied)
Jan 20 22:55:48 buildroot local4.debug slapd[728]: slapd stopped.

Also, your init script logging is not consistent with what we do in
other packages. You do:

        printf "Starting $DESC: $NAME: "
        start-stop-daemon -S -q -p $PIDFILE -x $DAEMON -- $ARGS
        echo "done."

While we normally do:

	printf "Starting dropbear sshd: "
	start-stop-daemon -S -q -p /var/run/dropbear.pid \
		--exec /usr/sbin/dropbear -- $DROPBEAR_ARGS
	[ $? = 0 ] && echo "OK" || echo "FAIL"

Also, there is something weird: when the daemon fails to start, it
doesn't show "done." (with your code) or "FAIL" (with my suggestion).
Can you have a look ?

Thanks,

Thomas
