Make sure that Directory Server is configured and running.
Enable the Referential Integrity plug-in using either the Directory Server Console or the ldapmodify command-line utility.
If you use the ldapmodify utility, load the Access Manager plugin.ldif file, which is available in the following directory, depending on your platform:
Solaris systems: /etc/opt/SUNWam/config/ldif
Linux and HP-UX systems: /etc/opt/sun/identity/config/ldif
javaes-install-dir represents the Java ES 5 installation directory. The default value is C:\Program Files\Sun\JavaES5.
Restart Directory Server to enable the plug-in.
