3.1.1.3.4.2.3 LDAP_TTL_REFRESH_OID
The presence of this OID in the supportedExtension attribute indicates that the DC provides support for dynamic objects as defined in [RFC2589]. This extended operation is sent to the DC to refresh a specific dynamic object that has already been created. The extended operation is documented in [RFC2589]. The refresh operation is treated as a modify operation (section 3.1.1.5.3) of the entryTTL attribute (section 3.1.1.4.5.12).
If the modify is successful, the responseTtl field ([RFC2589] section 4.2) is populated from the dynamic object's entryTTL constructed attribute according to section 3.1.1.4.5.12, using the msDS-Entry-Time-To-Die (section 3.1.1.5.3.3) and DynamicObjectMinTTL (section 3.1.1.3.4.7) attributes, and honoring the dynamic object's requirements, as specified in section 6.1.7.
