<!--
This view provides a workaround to logout from an external authentication provider, in case external
authentication was configured (the default is to handle authentications internally in Icingaweb2).
The <a href="http://tools.ietf.org/html/rfc2617">Http Basic and Digest Authentication</a> is not
designed to handle logout. When the user has provided valid credentials, the client is adviced to include these
in every further request until the browser was closed. To allow logout and to allow the user to change the
logged-in user this JavaScript provides a workaround to force a new authentication prompt in most browsers.
