!!! Overview
[{$pagename}] is an [Attribute] found in the [RootDSE] which specifies values of this attribute correspond to naming contexts which this [DSA] masters or shadows.

If the [DSA] does not master any information (e.g. it is an LDAP gateway to a public [X.500] directory) the [{$pagename}] attribute will be absent.  

If the [DSA] believes it contains the entire [Directory Information Base], the attribute will have a single value, and that value will be the empty string indicating the [null] [DN] of the top of the [Directory Information Tree]. 

[{$pagename}] attribute will allow a client ([DUA]) to choose suitable [BaseDN] for searching when it has contacted a [DSA].
