Kerberos is a network authentication protocol designed to allow nodes, communicating over a non-secure network, to prove their identity to one another in a secure manner. A Samba3 domain controller only supports NTLM, and Windows clients will not do Kerberos authentication without an AD- compatible KDC/directory. Negotiate is a container that uses Kerberos as the first authentication method, and if the authentication fails, NTLM is used. I will demonstrate with an example how Kerberos works. Apple has a mode where Kerberos, not NTLM is used in a workgroup The fileserver is a KDC for itself only Avoids the need to find the KDC No support on Windows or Samba clients Essentially a way of using the Kerberos key exchange in place of NTLM.
