I would suggest that you make an ldap call to the server using a DN
that you know will exist (e.g. just the base object, or use
cn=monitor
). You know the response (e.g. objectclasses in object), and can then
test to see if the response was the expected one. If it was not, then
you know there is a problem on the server, and can defer the message.
