[RADIATOR] hook for detecting directory connection problems

[Barry Ard]

Hello,
We are having problems with ldap directory connections failing and need 
to quickly detect the failures. The directory servers are run by a 
different group which have been slow to address the problems. The 
environment consists of a cluster of directory servers and we are told 
not to use persistent connections because of this. I am thinking a hook 
that would be processed when a connection fails and then 
FailureBackoffInterval is used would be perfect. Other suggestions are 
also welcome of course.
