 ticket: 6415
 subject: Use correct salt for canonicalized principals
 target_version: 1.7
 tags: pullup

 In cases where the salt is derived from the client principal, use the
 canonicalized principal received from the KDC to determine the salt.
 Further changes are probably required for some preauth cases.
