Gandi v5 Authentification

The V5 version of Gandi’s website is based on the OAuth2 framework: https://tools.ietf.org/html/rfc6749

Gandi v5 is not a monolithic application based on the single address www.gandi.net. Instead, it is distributed over multiple subdomains. Customers, however, only need to log in once (single sign-on) for access to all the v5 websites.
