From the CGI/1.1 Specification:

REMOTE_USER

If the server supports user authentication, and the script is protected, this is the username they have authenticated as.

Basically that means, that if your web-server enforces authentication to access the script in question, a browser who doesn't send accepted credentials will be denied access; if credentials are sent, it's up to the web-server to set the environment (of your script while executed) according to the specifications, which most servers will do...

Nevertheless it's up to you to code your scripts in a way, that they behave correctly under any possible circumstances; checking an env-var isn't that complicated after all :-)
