FromRFC4519: "The cn (commonName in X.500) attribute type contains names of an object. Each name is one value of this multivalued attribute. If the object corresponds to a person, it is typically the person's full name."


  • This attribute is often overloaded in the sense that many applications act as if this were "their" attribute, and therefore add values to this attribute as they see fit. Because of that it is impossible to give a precise and accurate definition of what this field means.
