Redirect_uri is ignored by auth0 oauth2 authentication

I’m using an oauth2 authentication.

When I invoke https://myoriginal.domain.com/login?client_id=[my id]&state=[state]&redirect_uri=differentdomain.thatis.whitelisted.com&response_type=code&scope=read%2Cwrite

I still get redirected back to https://myoriginal.domain.com/callback

Why?
