When performing this task one encounters one fundamental
difficulty: The /etc/shadow file is supposed to be
read/writable only by root.  However, the web server is
supposed to run under a non-root user, such as "nobody".
mod_auth_shadow addresses this difficulty by opening a pipe
to an suid root program, validate, which does the actual
validation.  When there is a failure, validate writes an
error message to the system log, and waits three seconds
before exiting.
