Does Horizon support external authentication via HTTPD?
So it seems that Keystone now is deployed with Apache and may rely on its authentication plugins. Once authentication is performed by the server it sets the REMOTE_USER
variable in the request, which Keystone then uses as proof of authentication.
How external authentication is compatible with Horizon in Juno release though? Are there still some code changes need to be done to Horizon to support Keystone setup with external authentication via HTTPD?
