[Pdns-users] powerdns hangs when ldap backend is unavailable

I totally agree. I even use a local ldap "slave" server (an openldap 
syncrepl consumer, on the powerdns box) using syncrepl (on openldap) to 
avoid any pdns service outage due to network problems which would 
prevent connectivity with ldap. (Thankfully, syncrepl does not hang when 
there is a network outage.) So, practically, I have minimized any 
problems. (This design also optimizes the speed of lookups [i.e. of DNS 
authoritative queries], since they are carried out locally, and no 
network activity is required.)

However, as you point out as well, I believe the problem is critical and 
should be treated.
