Problem with zone rsigning in 9.7.0

2010-03-24 Thread Roy Badami
I have a zone which is DNSSEC signed and is configured as a dynamic zone (although in practice dynamic updates are not normally used on this zone). AIUI BIND 9.7.0 should automatically resign the zone as required as long as the keys are available to it. However, what I actuallly found is that alt
