Hello, We are trying to get a service (a SMB server) running on Linux kerberized using the GSS API. During the negotiation (SPNEGO), the Windows SMB client specifies MS KRB5 (1.2.840.48018.1.2.2) as the preferred mechanism and supplies the initial token.

Challenging clients, why another ping-pong?

2014-02-03 Thread Rick van Rein
Hello, GSSAPI-based protocols have an option of challenging a client with a counter value. This is done after the client submits a ticket. Looking at SPNEGO (and probably other protocols as well) I see that the server can take the initiative for an GSSAPI exchange, and when doing so, it could
