!!! Overview
[{$pagename}] specifies the maximum number of entries that should be returned from the [SearchRequest].

Zero (0) implies there should is no [{$pagename}] on the entries to be returned.

[{$pagename}] is part of the [SearchRequest] parameters sent from the [DUA] and typically is also an Administrative setting on the [DSA].If either the [DSA] or [SearchRequest] [{$pagename}] setting is exceeded then the [LDAP_SIZELIMIT_EXCEEDED] [LDAP Result Code] should be returned.

!! [SearchRequest] Setting
The [SearchRequest] element for [{$pagename}] may be more restrictive than the [DSA] [{$pagename}] setting.

!! [DSA] Settings
The [DSA] [{$pagename}] is, depending on the [LDAP Server Implementation] a configuration option that controls the maximum number of entries that may be returned from any single [SearchRequest].  

Typically this is a [DSA] setting vs a [DIT] setting and depending on the [LDAP Server Implementation] may be overridden by a per-user configuration. That is, some [LDAP Server Implementations] can be configured to not enforce [DSA] [{$pagename}] limits for Administrative users.
