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.
