 ticket: 6501
 subject: Temporarily disable FAST PKINIT for 1.7 release
 tags: pullup
 target_version: 1.7

 There are protocol issues and implementation defects surrounding the
 combination of FAST an PKINIT currently.  To avoid impacting the 1.7
 scheduled and to avoid creating interoperability problems later,
 disable the combination until the problems are resolved.
