OID 11.1.1.6, configuring orclinmemfiltprocess to optimize search performance

Dears,

I was applying some tuning on our OID 11.1.1.6, following the doc http://docs.oracle.com/cd/E23943_01/core.1111/e10108/oid.htm#ASPER105
Under Optimizing Performance of Complex Search Filters, Optimizing Performance for Search baseDN section, it says:

In the DIT, if all the users are under one baseDN, such as cn=users,dc=acme,dc=com, and all the LDAP search clients send base as cn=users,dc=acme,dc=com, then the configuration of the orclinmemfilter will significantly reduce database processing time. See the following example:

orclinmemfiltprocess;dn: cn=users,dc=acme,dc=com

This matches our case, as we have all users under the same BaseDN, so I think we would benefit from that tuning. However, the document doesn't illustrate how to perform such task (or maybe it's not clear to me only)
