radiusd halts when LDAP bind fails.

[Scott McLane Gardner]

Hi list. I am trying to troubleshoot my radiusd occasionally halts when failing to bind with the LDAP server. I would prefer it to maybe wait a minute and restart rather than halting. Is this usual behavior? The wiki for rlm_ldap says:

set the uses, lifetime and idle_timeout settings in the pool section of the LDAP module to zero

But I have already set this value. I realize this means the server can't contact the LDAP server to do the auth, but I would prefer the service to be more resilient if possible. Preferably without having to do some cron or nagios scripting magic. (I'm open to it, but I wonder if there's a native handler for this?) Usually LDAP and radiusd are fine even very shortly after halting.
