[$] Authentication and authorization in Samba 4

By jake

Volker Lendecke is one of the first contributors to Samba,
having submitted his first patches in 1994. In addition to developing
other important file-sharing tools, he’s heavily involved in development of
the winbind service, which is implemented in winbindd. Although the core Active Directory (AD) domain controller
(DC) code was written by his colleague Stefan Metzmacher, winbind is a
crucial component of Samba’s AD functionality.
In his information-packed talk at FOSDEM
, Lendecke
said he aimed to give a high-level
overview of what AD and Samba authentication is, and in particular the
communication pathways and trust relationships between the parts of
Samba that authenticate a Samba user in an AD environment.
