Name        : mod_auth_shadow
Product     : Fedora EPEL 4
Version     : 2.2
Release     : 4.el4
URL         : http://mod-auth-shadow.sourceforge.net
Summary     : An Apache module for authentication using /etc/shadow
Description :

When performing this task one encounters one fundamental
difficulty: The /etc/shadow file is supposed to be
read/writeable only by root.  However, the webserver 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.
