cachesize does not exceed 1000 entries

[Robert Petkus <rpetkus@bnl.gov>]

Folks,
I'm running openldap version 2.3.4 configured to use an ldap database 
with a proxycache backend.  For whatever reason, I am unable to cache > 
1000 entries.  I must be missing something so obvious.  Any ideas?

Cheers,
Robert
