external login and logout in Gallery 1

Hello Gallery Community,

I have a problem that I thaught would be easy to solve but that now already annoys me for many days.

I have my own website, with my own session management, etc. The only thing I want to do is login or logout users via command line in the browser.

I just want to be able to open a link like
login.php?username=*****&password=******
to lock the user in

and one link like:
logout.php?username=*****
to lock the user out

Perfect would be the option to register and unregister user via command line as well, but that I can do manually, too. I remember from other big applications (for example Cassiopeia Chat Rooms) that they normally provide features like that to make integration in the own user management very easy.

HAS ANYBODY ANY GOOD ADVISE REGARDING THAT???

THANX A LOT!

Sebastian
