GUI login problem

Hi there guys,sorry for beeing such a lame,but iv just downloaded my first ever Asterix@Home (apparently called trixbox now), cuz it has all the basics already set up.
Therefore it seems impossible to log on via the browser. It simply doesnt take any login/password . I have heard that default are
login : maint
Pass : password

anyone would know ? or perhaps a solution how to add/setup gui login from my root panel? im a total lame with linux . So please be specific.

If it is freepbx based, look in /etc/amportal.conf
