From dd4877bfb6f09cb4a294b459b354c8fc8fa66904 Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Tue, 24 Oct 2006 18:33:17 -0400 Subject: [PATCH] knfsd: fix callback rpc cred It doesn't make sense to make the callback with credentials that the client made the setclientid with. Instead the spec requires that the callback occur with the credentials the client authenticated *to*. It probably doesn't matter what we use for auth_unix, and some more infrastructure will be needed for auth_gss, so let's just remove the cred lookup for now. Signed-off-by: J.
