matching rule ITU-T (X.500)

2.5.13.1

distinguishedNameMatch

DN equality done properly, component by component, rather than as a string compare. That is why cn=Bob,dc=example and cn=bob, dc=example can match: each RDN is normalized by its own attribute's rules, and the stray space stops mattering. Anyone who has tried to match DNs by hand learns to appreciate it.
