Here is a list of documentation and projects:
While Microsoft has designed a smart card logon method in active directory, stand alone computer can't use smart cards. EIDauthentication allows smartcard logon, without the need of a domain controller.
This project works very well with the Feitian PKI and the Feitian ePass PKI token.
Audience: workgroups using Active Directory
Status: validated and working
Microsoft has designed a smart card logon method in Active Directory, but this requires a Windows 2008 Server. The connection method using Windows 2008 Server is very described on Feitian CD.
A free software alternative to Active Directory server would be a Linux box running Kerberos + LDAP + Samba RPC. But our tutorial is not yet ready.
pGina open source authentication
Audience: workgroups using free software
Status: not validated
pGina is an open source authentication system that replaces the built in authentication of the Microsoft Windows operating system. pGina uses easy-to-write plugins that allow a system to authenticate against virtually any source. Some examples are LDAP, RADIUS, SSH, FTP, SMTP, POP3, and many more.
There used to be a smartcard plugin for pGina and the plugin needs to be revived. Please contact the developers for more information.
