Arvados

The old way of configuring the API server's SSO connection was to set globals in config/initializers/omniauth.rb.

The new way is to set various sso_* configuration settings in application.yml.

The API server installation guide documents the new configuration method, but our API server distribution packages always install omniauth.rb, effectively requiring users to use the old method. The API server distribution package should support and prefer the new configuration method.

Implementation:

• arvados-api-server-upgrade.sh (in arvados-dev) should only install omniauth.rb when it already exists in /etc/arvados/api.
• Update the install guide to remove references to installing omniauth.rb.
