Illustation environment
When a data conflict is introduced (multiple writes to the same entry in
different providers), there are three different strategies and they are
incompatible, see the attached test script for an example.
1. DeltaMPR providers have access to accesslog and reinterpret the operation as
if it happened in CSN order
2. Delta consumers (olcMultiProvider: FALSE) have the above code disabled so
have to accept the accesslog entry as-is, but the entry represents the
original, not reinterpreted write
3. plain syncrepl - just ignores the out of order version
This *cannot* (and does not) mesh well as at least 1. and 3. are always around
in deltaMPR.
