Authenticate Your Windows Clients Against... Anything

Nathan Yocom writes: "pGina is a GPL'd extension for the authentication portion of Windows 2000/XP. Why replace that portion of the OS? Because we don't like being forced to have a Windows server around just for user authentication. So pGina uses plugins to achieve modularity. This allows for user authentication via ANY number of means, both existing and future. For instance, there is already some work being done on an LDAP plugin, a SMB plugin, an SSH plugin and others (SQL, Kerberos, etc). For those who aren't developers it is easy to install, and for those who are developers, a simple yet powerful plugin SDK makes it easy to develop plugins. (Technically pGina should work in NT 4 as well, but we have NOT tested it)"
