I have been using PowerDNS plus PowerAdmin everytime I’m asked to build a web-frontend-enabled DNS system. Unfortunately the developers of PowerAdmin abandoned the project a while ago (last update was in 2004).
Wim Mostrey made an update to the 2 years old out-of-date PowerAdmin in March 2006. His patch introduces two new features for PowerAdmin.
When installing PowerAdmin, make sure that PEAR-DB and MySQL extension for PHP are installed. Otherwise it would produce an error message that’s not helpful (Oops! An error occured!). If those two are installed, then PowerAdmin should work properly.
