We are deprecating the OAuth 2.0 service provided by Globus Nexus (also known as GOAuth). Authentication interfaces in Globus Nexus are deprecated and will be discontinued April 30, 2017. Globus Auth was recently added to the Globus platform and includes support for the OAuth 2.0 and OpenID Connect (OIDC) protocols, along with richer and more fine-grained identity and access management.
