Dex is an identity service that uses OpenID Connect to drive authentication for other apps.
Dex is NOT a user-management system, but acts as a portal to other identity providers through "connectors."
This lets dex defer authentication to LDAP servers, SAML providers, or established identity providers like
GitHub, Google, and Active Directory. Clients write their authentication logic once to talk to dex, then
dex handles the protocols for a given backend.
