!!! Overview
[{$pagename}] is a [Component Matching Rule] defined in [RFC 3687] allows component [Relative Distinguished Name] ([RDN]) of a [DistinguishedName] ([DN]) to be evaluated.[{$pagename}] [MatchingRule] evaluates to [TRUE] if the [component value] and  [Assertion Value] are the same [RDN], using the same [RDN] comparison method as [distinguishedNameMatch].

The LDAP-specific encoding for a value of the RDN syntax is given by the [RelativeDistinguishedNameValue]  [Generic String Encoding Rules] ([GSER]) for [ASN.1] rule.
   

[{$pagename}] when used to match components of [DNs] it is important to note that the [LDAP]-specific [encoding] of a [DN] reverses the order of the RDNs.  So for the DN represented in LDAP as "cn=Steven Legg,o=Adacel,c=AU", the RDN "cn=Steven Legg" corresponds to the component reference "3", or alternatively, "-1".!! LDAP [Matching Rule] [{$pagename}] 
The LDAP definition for the [{$pagename}] [Matching Rule] is:
* [OID]: [1.2.36.79672281.1.13.3]
* [NAME]: [{$pagename}]
* [SYNTAX]: [1.2.36.79672281.1.5.0]
