When importing users from LDAP which includes 3000 members,
the error "paged results cookie is invalid" appears.
Users can be imported when set ldap.page.size property value as 5000, but
I tested with Java client which I made similar to Liferay's importing part,
But in this case I succeeded in get LDAP users even if ldap.page.size is 1000.
catalina.out ... the log includes import error "paged results cookie is invalid"
LDAPClientTest.java ... test code to import LDAP users by Java client code.
client.log ... log file by LDAPClientTest.java.
groupMapping.txt, userMapping.txt ... LDAP mapping used by LDAPClientTest.java.
