Authenticate users for a hotel through webpage?

Hi, maybe someone can point me to the right direction as it seems I use wrong keywords for my search in the list and on google. I am trying to use freeradius with wlan to authenticate hotel guests that need i-net access. They would prefer that the customer could visit a webpage entering the username / password combination they got at hotel-reception. Would this be a authentication methode which freeradius can handle or do I have to use other authentication modules for such a purpose? The most important thing is: Easy to use for the hotel staff at registering / deleting guests and easy to use for the guests at login. TIA and br, mfred
