Description of problem:

ns-slapd has a -d option to turn on debugging.  However, there is no way to
activate this in the init script.

I would recommend a setting such as SLAPD_DEBUG in the /etc/sysconfig/dirsrv or
/etc/sysconfig/dirsrv-$instance file (since we source that already) and code
such as:

[ -f /etc/sysconfig/dirsrv-$instance ] && . /etc/sysconfig/dirsrv-$instance
if [[ ! -z "$SLAPD_DEBUG" ]]; then
    DIRSRV_OPTS="-d $SLAPD_DEBUG"
else
    DIRSRV_OPTS=""
fi
$exec -D $instbase/slapd-$instance $DIRSRV_OPTS -i $pidfile -w $startpidfile

Version-Release number of selected component (if applicable):

389-ds-base-1.2.11.15-48.el6_6.x86_64

How reproducible:

Always

Steps to Reproduce:
1. Set "SLAPD_DEBUG=1" in /etc/sysconfig/dirsrv-$instance
2. service dirsrv restart
3. ps -ef | grep slapd

Actual results:

No -d option on command line of ns-slapd.

Expected results:

-d option and argument on command line of ns-slapd.
