!!! Overview
Each [attribute] stored in a Lightweight Directory Access Protocol [LDAP] directory, whose values may be transferred in the [LDAP] [protocol], has a defined [{$pagename}] that constrains the structure and format of its values.  


The comparison semantics for values of a [{$pagename}] are not part of the [{$pagename}] definition but are instead provided through separately defined [Matching Rule].  

[Matching Rules] specify an argument, an [Assertion Value], which also has a defined [{$pagename}].  

[Microsoft Active Directory] has several [{$pagename}] that are __NOT__ defined within [RFC 2252] or [RFC 4520][1]. We have accumulated them as best we can in  [Microsoft Active Directory Syntax]  

* [UPPERBOUND]


[{$pagename}] - per [RFC 4520] are defined within an [IANA Registry] [Lightweight Directory Access Protocol (LDAP) Parameters] located at: [LDAP Syntaxes|https://www.iana.org/assignments/ldap-parameters/ldap-parameters.xhtml#ldap-parameters-8|target='_blank']
