I'm working on configuring GitLab integrations, and this is requiring us to configure GitLab to traverse our proxy. I have declared both `http_proxy` and `https_proxy` variables within the gitlab_rails['env'] section of the `gitlab.rb` file like this: ``` gitlab_rails['env'] = { "http_proxy" => "http://USERNAME:PASSWORD@proxyaddress.com:8080", "https_proxy" => "http://USERNAME:PASSWORD@proxyaddress.com:8080", } ``` However, despite us having declared a username and password, we receive a response code of `407 Proxy Authentication Required`. When I spoke with someone who has access to the proxy, they said GitLab was not passing **any** username or password credentials to the proxy server. This appears to be a duplicate of <a href="https://gitlab.com/gitlab-org/omnibus-gitlab/issues/926">Issue 926</a>; this issue was closed, however the only solution appears to have been configuring the proxy to not require a username and password. Additionally, the last post appears to be from another user experiencing the same issue.
