If the directory is running vi {{F:slapd.d}}, then the following LDIF could be used to add the overlay to the overlay list
in {{B:cn=config}} and set what file the {{TERM:LDIF}} gets logged to (adjust to suit)
-> dn: cn=module{0},cn=config
-> changetype: modify
-> add: olcModuleLoad
-> olcModuleLoad: {2}auditlog.la
->
> dn: olcOverlay=auditlog,olcDatabase={1}hdb,cn=config
> changetype: add
> objectClass: olcOverlayConfig
An example for use with {{cn=config}}:
-> dn: cn=module{0},cn=config
-> changetype: modify
-> add: olcModuleLoad
-> olcModuleLoad: {1}constraint.la
->
> dn: olcOverlay=constraint,olcDatabase={1}hdb,cn=config
> changetype: add
> objectClass: olcOverlayConfig
H3: Overview
-This overlay supports dynamic objects, which have a limited life after
-which they expire and are automatically deleted.
-
+The {{dds}} overlay to {{slapd}}(8) implements dynamic objects as per RFC 2589.
+The name {{dds}} stands for Dynamic Directory Services. It allows to define
+dynamic objects, characterized by the {{dynamicObject}} objectClass.
+
+Dynamic objects have a limited lifetime, determined by a time-to-live (TTL)
+that can be refreshed by means of a specific refresh extended operation. This
+operation allows to set the Client Refresh Period (CRP), namely the period
+between refreshes that is required to preserve the dynamic object from expiration.
+The expiration time is computed by adding the requested TTL to the current time.
+When dynamic objects reach the end of their lifetime without being further
+refreshed, they are automatically {{deleted}}. There is no guarantee of immediate
+deletion, so clients should not count on it.
+
+Dynamic objects can have subordinates, provided these also are dynamic objects.
+RFC 2589 does not specify what the behavior of a dynamic directory service
+should be when a dynamic object with (dynamic) subordinates expires.
+In this implementation, the lifetime of dynamic objects with subordinates is prolonged
+until all the dynamic subordinates expire.
