Issue description

When trying to use an internal channel that makes use of simple authentication that mamba and conda supports reading from ~/.netrc pixi does not manage to reach the channel

Expected behavior

That ~/.netrc files are used for simple auth if they match the hostnames specified in a channel

Het this feels more like a feature request than a bug. So I'll change the tag to that.

All the fetching and auth logic is situated in rattler so if you would like to take a stab at it please feel free to do it there.

I don't know of a way to test this, but I assume this now is a feature we support? @baszalmstra

This should be fixed in rattler now.
