HTTP/JSON API for the PowerDNS authoritative DNS server.
This makes it easy to program DNS changes without every system having a database connection or full access to the DNS database.
There are basic installation instructions on the wiki.
The system needs an 'accounts' table and a 'cas' column in the domains table. The docs/schema.sql file has the SQL to be run to set this up.
For the 'CAS' API system to work properly, the system expects the transaction isolation level of MySQL to be 'REPEATABLE READ' (this is the default).
