Bug 481195 - Missing op type in log when password change required
    
    When a password change is required, non-password change operations
    are rejected with err=53.  The access log currently doesn't list
    anything about the operation type in the access log.  This is
    somewhat by design as we want to do as little processing as possible
    for rejected operations.  To be consistent with other code that
    does an early reject of operations (such as siabling anonymous
    access or SSF restrictions), we should explicitly log these as an
    "UNPROCESSED OPERATION".
