GitLab

works with "restrict all": in principle, this slapd should be started without any listener, if possible...

everything works without any need for changes in syncrepl code; only modifications when the remote consumer is down fail, but I'll track that later (back to work...)

	1) no full delete of an attribute;
	2) errors occurring when the remote consumer is off
	   are not recovered:
	3) I'm not too happy with running the internal search
	   with the syncrepl attrlist
