An identifier that uniquely represents an object in the X.500 Directory Information Tree (DIT) [X501]. (Compare: domain name, identity, naming authority.)
Tutorial: A DN is a set of attribute values that identify the path leading from the base of the DIT to the object that is named. An X.509 public-key certificate or CRL contains a DN that identifies its issuer, and an X.509 attribute certificate contains a DN or other form of name that identifies its subject.
