Really? It seems to use the REMOTE_USER variable when I've tried it.

Looking at the source code, it seems to check the environment.

If Plack is translating headers into special environment variables, then
it's a matter of telling A::C::Remote a different source.  What would be the
name?

I'm running the Plack server directly, not FCGI, and using a reverse proxy.
