Change the API used to test credentials for Codebase HQ.
Review Request #8156 — Created May 12, 2016 and submitted
To test authentication credentials for Codebase HQ, we were performing an HTTP GET to the roles API. However, it turns out that not all users can access this resource, so it makes for a bad test. Instead, we're now accessing the API for the user's public keys, which is allowed for any given user, fixing the authentication test.
Unit tests pass.
Had a customer test this API for their restricted user.
