For all the Windows clients this went automatically due to domain policies, for Linux this has to be set up manually. Defining the proxy in /etc/environment was not enough since NTML authentication is required, which is not supported by default. I found cntlm, a piece of software which acts as a local proxy, translating all requests to authenticated NTLM requests to your upstream proxy. This guide covers the (offline) installation, setup, getting the correct password hash and system-wide configuration. It should work on a desktop as well, but I did not test that.
