Looking into my binocular crystal ball, I see two things:

Left eye: You're trying to write a basic auth client, and want
something to test it on. See Hans's response.

Right eye: You want to write a basic auth server, and you need to know
how to return a 401.

Please provide 1.5 metric tons of additional information. What are you
trying to do, what libraries are you using, what's the failing code?
