Yeah, it seems we need to figure out a way to wait for it to be ready
to accept connections. I wondered how other people do this, and found
one example that polls for the .pid file:
https://github.com/tiredofit/docker-openldap/blob/master/install/etc/cont-init.d/10-openldap#L347
That looks nice and tidy but I'm not sure it can be trusted, given
that OpenLDAP's own tests poll a trivial ldapsearch (also based on a
cursory glance at slapd/main.c which appears to write the .pid file a
bit too early, though I may have misread):
https://github.com/openldap/openldap/blob/master/tests/scripts/test039-glue-ldap-concurrency#L59
I guess we should do that too. I don't know how to write Perl but I'll try...
