One example is the distinguishedNameMatch rule. If the assertion value is
a DN where one of the AVAs contains an attribute type that is unknown to the
directory server then the server cannot compare such an AVA and would have to
return "undefined" if required to do the comparison.

There are various other examples where an LDAP server might have to compare
an object descriptor to an OID. If the object descriptor isn't known to the
server then it has to return "undefined" if called upon to perform a comparison.
