Writing a custom authentication helper

There is no need to worry if none of the existing authentication helpers seem to fit your needs. It is possible to write your own HTTP Basic authentication helper relatively quickly. The HTTP Basic authentication helpers are very simple programs that read username password strings from standard input, extract the username and password from the string, match them against an existing user database, and then write OK or ERR on the standard output in a never ending loop.
