By default eduTEAMS Discovery Service lists all eduGAIN IdPs for user to select from. This is not always desirable and eduTEAMS Discovery Service offers possibility to filter out IdPs. This allows SP admin to craft a list (or several lists) specifically targeting the user base of the SP. If for nothing else, the filtering should be used to hide IdPs not meant to be shown for 'normal' end user i.e. IdPs having entity category http://refeds.org/category/hide-from-discovery.
