The Open Source Zone

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.

Pubcookie currently includes a login server component as well as modules for Apache and Microsoft IIS servers that host content and applications. It also comes with tools for managing and distributing encryption keys.
