By default eduTEAMS Discovery Service lists all eduGAIN IdPs for user to select from. This is not always desirable and therefore eduTEAMS Discovery Service offers possiblity to filter IdPs from the list. This allows SP admin to craft a list (or several lists) specifically targeting the user base of the SP.
The filter is generated using eduTEAMS Filter Generator. The filter consists of two filtering types.
You may create both allow and deny lists of entity categories.
You may create allow or deny list of IdPs.
When both entity categories and idp list filters are used together, the list shown comprises of IdPs not filtered out by categories filter with possible additions of IdP allow list or possible deductions of IdP deny list.
