Hi,
we want entries to be replicated to a public slave, only if they have an
attribute worldreadable=TRUE.
So I've setup an ACL on the master which basically is like
access to * filter=(worldreadable=FALSE)
by * none
access to *
by * read
Thus, the consumer only sees entries it is allowed to replicate.
Now if an entry's worldreadable attribute is changed from TRUE to false,
this modification will not propagate to the consumer and the entry stays
visible.
However, with refreshOnly this 'lost' entry is detected and removed
(syncrepl_del_nonpresent).
