I'm using WordPress MU 18.104.22.168 and ext_db_auth 3.12. The plugin works to allow users to login to the root blog (http://www.classcaster.net/), but fails to allow logins to child blogs (http://anotherblog.classcaster.net/). I've tried this with multiple versions of WPMU and the plugin and placing the plugin in either the plugins or mu-plugins directory and the result is always the same. The settings for the plugin do not transfer forward to new blogs that are created. It is important to me that logins on the child blogs are authenticated against the external database. Any suggestions on how to get the values to roll forward as new blogs are created?
