Bug 476925 - Admin Server: Do not allow 8-bit passwords for the admin user
    
    https://bugzilla.redhat.com/show_bug.cgi?id=476925
    
    Description: Due to the following reasons, password of the admin
    user is not supposed to include 8-bit characters.
    1) Admin Console | Configure | Access does not take 8-bit password.
       If such characters are entered, the characters are dropped.
       (e.g., if "députés" is entered, the password will be "dputs".
    2) Character encoding of Admin Express's login window depends on
       browsers' implementation.  And the server has no way to get
       the character encoding information.
    Despite of it, setup-ds-admin.pl accepts 8-bit admin user password.
    This patch changes the behavior and rejects it.
