Pubcookie is an open-source package for intra-institutional single-sign-on end-user web authentication. More generally, it is an approach to identifying users as they browse to an institution's many websites that require authentication. It helps an institution reuse existing authentication services (like Kerberos, LDAP, or NIS), and it limits the exposure of end-user passwords by ensuring they're only sent to a trusted login service. This port contains the Apache module portion of the Pubcookie system. WWW: http://pubcookie.org/
