!!! Overview
[{$pagename}] can be used to view and modify the [LDAP policy in Active Directory]
!! [Example]
As an example, modifying the [MaxPageSize] limit using Ntdsutil.exe. You would:
There is a [maxPageSize] limit of 1000 in the windows AD which limits the [LDAP] query records to a max of 1000. In simple words whenever an LDAP search or query is made to the AD, no more than 1000 records are returned from the directory. This limitation is actually a security design so as to prevent the [Microsoft Active Directory] from [Denial-of-Service] attacks for [LDAP] queries. In case less than 1000 users are defined in the AD, no additional work is required but for a large setup this limit needs to be changed at the AD using the [{$pagename}] utility. So the following steps need to be done at your AD to change the [MaxPageSize] value from 1000 to 3000.
