The Directory Server tuning script creates the following indexes if they do not already exist:
Index for attributes that are used to search for a user to be authenticated
Indexes for the default Access Manager attributes: nsroledn, memberof, iplanet-am-static-group-dn, iplanet-am-modifiable-by, iplanet-am-user-federation-info-key, sunxmlkeyvalue, o, ou, sunPreferredDomain, associatedDomain, and sunOrganizationAlias
These attributes are indexed during installation by using the index.ldif file in /etc/opt/SUNWam/config/ldif directory on Solaris systems and /etc/opt/sun/identity/config/ldif directory on Linux systems. If for some reason, any of these attributes are not indexed, the Directory Server tuning script creates them.
For more information about indexes, see Appendix A, Directory Server Considerations, in Sun Java System Access Manager 7.1 Postinstallation Guide.
