What Does the SSO Plugin Expect for Oauth2?

[c.k. lester]

I'm trying to do some Oauth2 integration, and I need to know what a few of these variables are expecting in this part of the code:

oauth2: {
authorizationURL: 'https://mywebsite.com/oauth/authorize', <-- Does that look right?
tokenURL: '[WHAT GOES HERE?]',
clientID: 'CLIENT-ID',
clientSecret: 'THE-SECRET'
},

// what might userRoute look like?!
userRoute: ''	// This is the address to your app's "user profile" API endpoint (expects JSON)

Thank you!
