Kerberos is a networked authentication system developed at the Massachusetts Institute of Technology.[1], A central trusted "ticket-granting server" provides "tickets" which allow other machines to authenticate each other. Granting of specific rights, called credentialing, to authenticated machines can be by a separate secure server.
Specifications and documentation
The Kerberos protocol is specified in RFC 4120. There is an active working group at the IETF with many more documents. Microsoft's usage is documented in RFC 3244 and RFC 4757.
There is a FAQ. IBM provide a Kerberos primer.
Architecture
The separation of credentialing from authentication is not part of all authentication systems, but offers the ability to separate the administration of those two functions, which is a check-and-balance for personnel security of administators.
Vendor use
Kerberos has been used (not without controversy [1]) by all versions of Microsoft Windows since Windows 2000 [2]. It is also used by various Unix-based systems, including Sun, Apple, HP and IBM.
