Have you taken a look at the Solaris inclusion of gssapi parts in their kernel: http://fxr.watson.org/fxr/source/common/gssapi/?v=OPENSOLARIS I assume this is associated with NFSv4 support, but haven't dug around at all yet other than noticing it there the other day. Most other discussion of GSSAPI I've seen assumes that the crypto takes place in user space, but having it in kernel has some significant advantages (especially if you have a fully preemptive kernel, which we now have).
