3.1.1.3.1.1.2 Syntaxes
The syntaxes used in Active Directory are based on [RFC2252] section 6. Where Active Directory and [RFC2252] have syntaxes in common, the same means of encoding the value into the syntax is used. However, Active Directory has a number of syntaxes that are not defined in [RFC2252], and vice versa. Additionally, even when Active Directory and [RFC2252] have syntaxes in common, in many cases they use different names for the same syntax, and in all cases they use different OIDs to identify the same syntax.
Active Directory does not use the syntaxes defined in [RFC2256] section 6. The list of syntaxes in Active Directory, their encodings, and how they map to the [RFC2252] syntaxes are documented in section 3.1.1.2.2.
