!!! Overview
[{$pagename}] is the [LDAPDisplayName] for [MAPI-ID] an [Attribute] within [Microsoft Active Directory] which is an integer by which [MAPI] clients identify this attribute.


%%information
[{$pagename}] is __NOT__ present on [attributeSchema] objects in [ADAM].

!! Auto-Generated [{$pagename}]
If the DC functional level is DS_BEHAVIOR_WIN2008 or greater, and an [attributeSchema] object is created with LDAP Add, and the Add request assigns the [OID] [1.2.840.113556.1.2.49] as the value of the [{$pagename}] attribute, the [Domain Controller] sets the [{$pagename}] attribute to an [integer] that does not already appear as the [{$pagename}] on a schema object. An implementation can use any [algorithm] to choose the next [integer] as long as that algorithm satisfies this uniqueness constraint. This [{$pagename}] uniqueness spans all the [{$pagename}] attributes on schema objects that are currently persisted in the directory.


The aforementioned value that triggers auto-generation behavior for [{$pagename}] is of syntax String (Object-Identifier), which does not conform to the declared syntax of the [{$pagename}] attribute. The [Domain Controller] accepts these values without the error that would normally occur in such a case.
