        Bug Description:  In a replication environment, if you have one master set with
                          passwordIsGlobalpolicy to on, and another master does not, then
                          the password policy updates are rejected.  However, there is no
                          clear logging to tell you why the operatoin was rejected.
    
        Fix Description:  Write a clear message in the error log stating what was the cause
                          of the failure.
