Can anyone recommend an open source tool for managing DNS, similar to the web applications used by hosting providers? I'm thinking about opendns, godaddy, freedns, etc. Some of the DNS servers have web management tools, but I want a large scale tool. It should handle 100k zones and 1M records, support SSO, and accommodate load balanced app servers.

If you are willing to drop Bind as a DNS server, check out PowerDNS in combination with PowerAdmin - not sure if it features everything you want but according to their site it certainly scales. PowerDNS is available as an open source (free) version and commercially, backed with support.
There is also Tupa, another front-end for PowerDNS - more feature rich but somewhat outdated or so it seems.
