[RADIATOR] hook for detecting directory connection problems

[Barry Ard]

Thanks Hugh, I guess I didn't explain myself very well. I have omitted 
the HoldServerConnection parameter and tweaked the Timeout and 
FailureBackoffTime parameters but as I don't control the ldap servers 
and we experience connection failures which result in the 
FailureBackoffTime to be triggered I was just looking for a mechanism to 
alert us to this situation (So we can alert the group in charge of ldap 
prior to our helpdesk receiving complaints from users). Once the ldap 
server connection fails they don't recover and whatever we set for 
FailureBackoffTime doesn't matter. Something like a LDAPConnectionHook 
would easily address this situation but I am up for other suggestions 
but hopefully something more elegant than scan the log files.
