This paper will discuss the workings and benefits of Kerberos, focusing on its single sign-on capabilities, its multipronged security, and its ease of use.

Kerberos is a computer network authentication protocol that allows end-users in client-server environments to identify themselves more securely. Most notably, Kerberos allows end-users to reduce the number of passwords they possess and the number of logon attempts they need to make to just one. It also encrypts the end-users' identity so it is not openly sent over the network. Organizations find that Kerberos is a highly secure authentication method that delivers huge benefits for both end-users and administrators, and it contributes to improving their overall security.

Kerberos has become the most popular cross-platform, network-wide authentication system available, as it is now deeply integrated with Microsoft Windows and Active Directory. As a leading provider of password management products integrating Active Directory, PistolStar has developed a Kerberos-based solution using Active Directory as an option for customers who want a server-side product that enables them to execute single sign-on to gain access to all their Lotus Domino servers. The Password Power Plug-In for Domino SSO via Kerberos combines all the benefits of Kerberos authentication with the convenience and ease of use typically found in Password Power.
