FATAL: Missing required environment variables
-------------------------------------------------------------------------------
If using an openid authentication, you must provide each of the following
environment variables:
OPENID_AUTHORIZATION_ENDPOINT The authorization endpoint (URI) of the OpenID service.
OPENID_JWKS_ENDPOINT The endpoint (URI) of the JWKS service which defines
how received ID tokens (JSON Web Tokens or JWTs)
shall be validated.
OPENID_ISSUER The issuer to expect for all received ID tokens.
OPENID_CLIENT_ID The OpenID client ID which should be submitted
to the OpenID service when necessary.
This value is typically provided to you by the OpenID
service when OpenID credentials are generated for your application.
OPENID_REDIRECT_URI The URI that should be submitted to the OpenID service such that
they can redirect the authenticated user back to Guacamole after
the authentication process is complete. This must be the full URL
that a user would enter into their browser to access Guacamole.
