Currently, a mostly-empty Git repo.
When I have time, I will write a simple GSSAPI provider that lets users on trusted servers acquire session tickets and authenticate against remote services transparently.
A gssundheit
deamon runs on the trusted server (as an unprivileged user), and
listens to a well-known UNIX socket (say, /var/run/gssundheit.sock
).
When a user connects to the socket, the deamon authenticates them using
SO_PEERCRED
(basically, asking the kernel for which UID is at the other end
of the socket) and sends a signed authentication ticket with auxiliary
metadata used to support GSSAPI features (such as channel bindings).
-
The two primary goals are simplicity and security: GSSundheit should be simple to use and simple to audit.
-
The main usecase for GSSundheit is through a SASL authentication service, like auth, but GSSAPI is a generic API and any other kind of service may leverage it.
-
Some optional features of GSSAPI are considered especially desireable:
- channel binding, see RFC 5056.
