svn rev #22781: trunk/src/kadmin/cli/

[ghudson@MIT.EDU]

Commit By: ghudson
Log Message:
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.
