I have a github user that can successfully start jobs from the web interface, but it receives a 403 Forbidden error with the "<username> is missing the Overall/Read permission" message when I try to trigger the job via a buildWithParameters call.

Example:
curl -v -sS http://my-github-user:912h...e29@jenkins.company.com/job/client-set-max-version/buildWithParameters -d READ_ONLY=true

The issue was raised 5 months ago on mocleiri's github repo(https://github.com/mocleiri/github-oauth-plugin/issues/42), but it's been pretty quiet since. The only workaround I can manage is to add the user as an admin under the plugin settings. It's unfortunate that this is necessary since it's just an automation account that has no business being an admin on anything.
