NAME         top

       slapo-syncprov - Sync Provider overlay to slapd

SYNOPSIS         top

       ETCDIR/slapd.conf

DESCRIPTION         top

       The Sync Provider overlay implements the provider-side support for
       the LDAP Content Synchronization (RFC4533) as well as syncrepl
       replication support.  The overlay can be used with any backend that
       maintains entryCSN and entryUUID attributes for its entries. It also
       creates a contextCSN attribute in the root entry of the database.

       The contextCSN is updated for every write operation performed against
       the database. To reduce database contention, the contextCSN is only
       updated in memory. The value is written to the database on server
       shutdown and read into memory on startup, and maintained in memory
       thereafter. Checkpoints may be configured to write the contextCSN
       into the underlying database to minimize recovery time after an
       unclean shutdown.

       On databases that support inequality indexing, it is helpful to set
       an eq index on the entryCSN attribute when using this overlay.

CONFIGURATION         top

       These slapd.conf options apply to the Sync Provider overlay.  They
       should appear after the overlay directive.

       syncprov-checkpoint <ops> <minutes>
              After a write operation has succeeded, write the contextCSN to
              the underlying database if <ops> write operations or more than
              <minutes> time have passed since the last checkpoint.
              Checkpointing is disabled by default.

       syncprov-sessionlog <ops>
              Configures an in-memory session log for recording information
              about write operations made on the database.  The <ops>
              specifies the number of operations that are recorded in the
              log. All write operations (except Adds) are recorded in the
              log.  When using the session log, it is helpful to set an eq
              index on the entryUUID attribute in the underlying database.

       syncprov-nopresent TRUE | FALSE
              Specify that the Present phase of refreshing should be
              skipped. This value should only be set TRUE for a syncprov
              instance on top of a log database (such as one managed by the
              accesslog overlay).  The default is FALSE.

       syncprov-reloadhint TRUE | FALSE
              Specify that the overlay should honor the reloadHint flag in
              the Sync Control. It must be set TRUE when using the accesslog
              overlay for delta-based syncrepl replication support.  The
              default is FALSE.
