Service Provider Login Link Composer
This web page lets one compose login links for a Shibboleth-protected resource. The link will redirect users directly to a specific Home Organization for authentication. This way users will skip the WAYF/Discovery Service.
Example link: Login via SWITCH (SWITCHaai)
However, in case your resource has users from more than a hand full of different organizations, it is recommended to use a WAYF/Discovery Service or the embedded WAYF.
