Retro Change Logging
Directory Server ships with a retro changelog plug-in that you may enable to
record changes on a supplier server in a format compatible with Directory Server
4.x releases and accessible through LDAP. The retro changelog plug-in is disabled
by default and should not be enabled unless required for compatibility reasons.
Refer to the Sun ONE Directory Server Reference Manual for details. Table 8-6
provides further recommendations for specific attributes.
