OSIN is an OAuth2 server library for the Go language, as specified at http://tools.ietf.org/html/rfc6749 and http://tools.ietf.org/html/draft-ietf-oauth-v2-10.
Using it, you can build your own OAuth2 authentication service.
The library implements the majority of the specification, like authorization and token endpoints, and authorization code, implicit, resource owner and client credentials grant types.
