// XXX: To date, npm Enterprise Legacy is the only system that ever
// implemented support for this type of login. A better way to do
// SSO is to use the WebLogin type of login supported by the npm-login
// module. This more forward-looking login style is, ironically,
// supported by the '--auth-type=legacy' type of login.
// When and if npm Enterprise Legacy is no longer supported by the npm
// CLI, we can remove this, and fold the lib/auth/legacy.js back into
// lib/adduser.js
