Red Hat Directory Server LDAP search takes too long, notes=U in access log

Solution Verified - Updated -


LDAP searches take a long time and show notes=U in the access log, when the number of objects is greater than 4000.
An ldapsearch filter of objectclass=nstombstone took 3 seconds when the number of objects was < 4000, 21 minutes when > 4000.
