entryUUID Plugin
The entryUUID Plugin generates values for the entryUUID operational attribute whenever an entry is added via protocol or imported from LDIF.
The entryUUID plug-in ensures that all entries added to the server, whether through an LDAP add operation or via an LDIF import, are assigned an entryUUID operational attribute if they do not already have one. The entryUUID attribute contains a universally unique identifier that can be used to identify an entry in a manner that does not change (even in the event of a modify DN operation). This plug-in generates a random UUID for entries created by an add operation, but the UUID is constructed from the DN of the entry during an LDIF import (which means that the same LDIF file can be imported on different systems but still get the same value for the entryUUID attribute). This behavior is based on the specification contained in RFC 4530. The implementation for the entry UUID plug-in is contained in the org.opends.server.plugins.EntryUUIDPlugin class. It must be configured with the preOperationAdd and ldifImport plug-in types, but it does not have any other custom configuration. This plug-in must be enabled in any directory that is intended to be used in a synchronization environment.
