!!! Overview 
A [{$pagename}] (aka "[Pseudo Attribute]", "[Constructed Attribute]" or "Back-link" where the value is calculated by the [LDAP Server Implementation] and is not Actually part of the [LDAP Entry].

A [{$pagename}] is a type of [AttributeTypes] in which the [Attribute Value] are not actually stored in the [Back-end] but are rather dynamically generated in some manner.

[{$pagename}]s may or may NOT be part of the entry's defined [ObjectClass Type] and sometimes any [ObjectClass Type].  

The values may be obtained in various manners, depending on the type of [{$pagename}].

Some [{$pagename}] use a hard-coded value, while others compute their values at runtime based on some kind of logic.

[Microsoft Active Directory] uses the term "back-link" (means the same as [{$pagename}]) in regards to [MemberOf] attribute.
