Consumer slapd emits endless

		5babd9c4 do_syncrep2: rid=001 (4096) Content Sync Refresh Required

messages when the provider has an empty accesslog (because it was freshly setup
and nothing has been added/updated since then). This issue was mentioned back in
2013 (see http://www.openldap.org/lists/openldap-technical/201301/msg00229.html)
already but it looks like it was not reported.

The provider likewise logs

5babd9cf conn=1000 op=60677 SRCH base="dc=company,dc=com" scope=2 deref=0
filter="(objectClass=*)"
5babd9cf conn=1000 op=60677 SRCH attr=* +
5babd9cf conn=1000 op=60677 SEARCH RESULT tag=101 err=0 nentries=0 text=

for every attempt from the consumer to lookup records in the accesslog.
