WLCG Bearer Token Discovery

WLCG Authorization Working Group

This document defines a specification for the discovery of WLCG bearer tokens by client tools. Client tools that rely on a bearer token for authenticating themselves need a mechanism for receiving the tokens from their environment. While the browser is a monolithic user agent (and can internally manage tokens), the terminal environment involves a number of independently-developed tools; the environment needs a way to communicate the token to be used to Unix processes. To the best of our knowledge, there's no previously defined standard about how a Unix tool should discover a token from its environment.
