Please don't attach screenshots of text.  If you have questions, use text
email.

In general, however:

One database is used as the main database for the system. Lets call this
database A.
One database is used to store the accesslog data (the change deltas). Lets
call this database B.
There may be other databases on the system (such as the monitor database).
Lets call this database C.

Both the syncprov and accesslog *overlays* must be configured on database A
with the appropriate configuration options.

The syncprov overlay must *also* be configured on database B with the
appropriate (but different) configuration options to indicate it's an
accesslog DB.

In cn=config, every database has a weight that indicates the order in which
it loads.  So:

olcDatabase={1}... is the first DB to get loaded by slapd (Ignoring {-1}
and {0} which always exist, and are the frontend and config DBs
respectively).

olcDatabase={2}... would be the second DB to get loaded by slapd

olcDatabase={3}... would be the third DB to get loaded by slapd

Additionally, overlays have weights associated with them to indicate the
order in which they get loaded.  So:

olcOverlay={1}...,olcDatabase={2}... means that this overlay is the first
one that gets loaded for database #2.

In the EXAMPLE I provided on my blog:

olcDatabase={1} is the monitoring database (database C above)

olcDatabase={2} is the ACCESSLOG database (database B above)

olcDatabase={3} is the MAIN database (database A above)

So which overlays need to apply to which databases depends ENTIRELY ON THE
ORDER in which they are defined in *YOUR* configuration.  You need to make
adjustments accordingly.
