Public bug reported:

when starting opendkim, if ldap is in use and the server cannot be
contacted, opendkim gets stuck in a state where the system appears to
think it has started, but is not actually running:

>systemctl -l status opendkim
● opendkim.service - LSB: Start the OpenDKIM service
   Loaded: loaded (/etc/init.d/opendkim)
   Active: active (exited) since Wed 2015-05-06 23:16:20 EDT; 1min 24s ago

>ps -aefwww | grep -iF dkim
root       858   815  0 23:18 pts/0    00:00:00 grep -iF dkim

additional attempts to start opendkim don't indicate failure, but also
don't work:

>systemctl start opendkim
>

>ps -aefwww | grep -iF dkim
root       863   815  0 23:19 pts/0    00:00:00 grep -iF dkim

additionally, as can be seen in the above systemctl status output,
systemd appears to think that opendkim has started successfully, but
when testing manually, it does not:

>/usr/sbin/opendkim -x /etc/opendkim/opendkim.conf -u opendkim -P /var/run/opendkim/opendkim.pid
opendkim: /etc/opendkim/opendkim.conf: ldap://dsa.example.com/ou=domains,ou=mail,dc=example,dc=com?host?sub?(host=$d): dkimf_db_open(): Can't contact LDAP server

>echo $?
78

lastly, stopping opendkim [even though it's not really running] and then
starting it again then results in it actually running:

>systemctl stop opendkim

>systemctl start opendkim

>ps -aefwww | grep -iF opendkim
opendkim  1105     1  0 23:24 ?        00:00:00 /usr/sbin/opendkim -x /etc/opendkim/opendkim.conf -u opendkim -P /var/run/opendkim/opendkim.pid
opendkim  1106  1105  0 23:24 ?        00:00:00 /usr/sbin/opendkim -x /etc/opendkim/opendkim.conf -u opendkim -P /var/run/opendkim/opendkim.pid
root      1117   815  0 23:25 pts/0    00:00:00 grep -iF opendkim
