## Configure the redirection when the authz failure occurs. Lines starting with 'Modern Method' and 'Legacy Method'
|
|
## should be commented / uncommented as pairs. The modern method uses the session cookies configuration's authelia_url
|
|
## value to determine the redirection URL here. It's much simpler and compatible with the mutli-cookie domain easily.
|
|
|
|
## Modern Method: Set the $redirection_url to the Location header of the response to the Authz endpoint.
|
|
auth_request_set $redirection_url $upstream_http_location;
|
|
|
|
## Modern Method: When there is a 401 response code from the authz endpoint redirect to the $redirection_url.

|
error_page 401 =302 $redirection_url;
|
|
|
|
## Legacy Method: Set $target_url to the original requested URL.
|
|
## This requires http_set_misc module, replace 'set_escape_uri' with 'set' if you don't have this module.
|
|
# set_escape_uri $target_url $scheme://$http_host$request_uri;
|
|
|
|
## Legacy Method: When there is a 401 response code from the authz endpoint redirect to the portal with the 'rd'
|
|
## URL parameter set to $target_url. This requires users update 'auth.shobu.fr/' with their external authelia URL.
|

# error_page 401 =302 https://auth.shobu.fr/?rd=$target_url;
