为了实现基本的身份validation与Apache服务器和插件的代理部分工作很好，但是当我尝试瓶坯请求，假设触发mod_authn_dbd及其依赖项的即时通讯得到这个错误：
[Sat Sep 03 17:42:38 2011] [error] (OS 126)The specified module could not be found. : DBD: failed to initialise [Sat Sep 03 17:42:38 2011] [error] [client 192.168.16.2] Failed to acquire database connection to look up user 'admin' 这里是我的configuration：

什么即时做错了？ MySQL工作（phpMyadmin工作很好）和Apache代理工作很好。
如果你使用64位窗口和64位的mysql，试着用32位版本更改mysql。 或者你可以把mysql 5.0 32位的libmysql.dll放在apache的bin目录下。 可以从mysql.org档案获取mysql 5.0作为zip文件。
