Matching rules are also used in evaluating search filter elements, including distinguished names (DNs) and attributes. They are defined for each attribute based on the following properties:

  • EQUALITY: two attributes are equal based on case, exact match, and so forth
  • SUBSTR: assertion value is a substring of an attribute
  • ORDERING: greater than or equal, less than or equal, and so forth
Note:

PingDirectory Server supports an APPROXIMATE matching rule that compares similar attributes based on fuzzy logic. Attributes that are similar or sound alike are matched. For example, petersen would match peterson.
