 ticket: 6420
 subject: Add LDAP back end support for canonical name attribute
 tags: pullup
 target_version: 1.7

 Add a krbCanonicalName attribute to the schema.  When looking up a
 principal, if the canonical name is set and does not match the
 requested name, then return the entry only if canonicalization was
 requested, and use the entry's canonical name.
