 ticket: 6568
 subject: Fix addprinc -randkey when policy requires multiple character classes
 tags: pullup
 target_version: 1.7.1

 The fix for ticket #6074 (r20650) caused a partial regression of
 ticket #115 (r9210) because the dummy password contained only one
 character class.  As a minimal 1.7 fix, use all five character classes
 in the dummy password.
