Provide a configuration option that makes it possible for the administrator to
control whether responses to failed bind operations include an error message
that explains the problem.  By default, failed bind operations will return a
response that indicates the operation failed, but will not include any error
message (although it will be written to the access log).  However, if the
administrator decides that the benefit of providing this information to the
client outweighs any potential security risk, then this option may be used to
include that message in the response to the client as well as having it written
to the access log.
