1 Scope This Recommendation | International Standard defines a number of object classes and name forms which may be found useful across a range of applications of the Directory. The definition of an object class involves listing a number of attribute types which are relevant to objects of that class. The definition of a name form involves naming the object class to which it applies and listing…

1 Scope This Recommendation | International Standard addresses some of the security requirements in the areas of authentication and other security services through the provision of a set of frameworks upon which full services can be based. Specifically, this Recommendation | International Standard defines frameworks for: –public-key certificates; and –attribute certificates. The public-key…

1 Scope The Directory provides the directory capabilities required by many application layer standards and telecommunication services. Among the capabilities which it provides are those of "user-friendly naming", whereby objects can be referred to by names which are suitable for citing by human users (though not all objects need have user-friendly names); and "name-to-address…

1 Scope This Recommendation | International Standard defines a number of attribute types and matching rules which may be found useful across a range of applications of the Directory. Attribute types and matching rules fall into three categories, as described below. Some attribute types and matching rules are used by a wide variety of applications or are understood and/or used by the Directory…
