Error in dialupadmin

Hi, This is my first time using FreeRADIUS. It's running on Debian 6 and yesterday I installed freeradius-dialupadmin package. Read HOWTO.gz and README.Debian, and still not working. Home page looks fine but when I go to Accounting or New User button it shows an error DEBUG(SQL,MYSQL DRIVER): Connect: User=XXX,Password=XXX (I'm protecting credentials, of course) error.log in apache2 doesn't say something relevant but some warnings (PHP notice). Anybody with same issue? Thanks in advance. Alberto Mijares
