Openfire LDAP issue relating to page size

We use Active Directory as our LDAP server for Openfire.

However, it would seem that by default, the maximum number of users it supports is 1000 (which matches the AD default pagesize).

If I increase the pagesize on AD, I can see more users. Is there any way to tell Openfire to read multiple small pages so I don’'t have to change my production AD environment globally?
