Bug 182507 - clear-password mod from replica is discarded before changelogged
    
    https://bugzilla.redhat.com/show_bug.cgi?id=182507
    
    Description:
    Replication drops unhashed passwords which is necessary for
    the AD password sync.  This patch allows the passwords replicated
    and introduces a method to encrypt logs in the changelog.
