When we did this, we added a new option to cifs.upcall (--legacy-uid) to try to make it so that it would behave the same was as it did before. This ignored a rather important point -- the kernel has no way to know what options are being passed to cifs.upcall, so it doesn't know what uid it should use to determine whether to match an existing krb5 session. The simplest solution is to simply add a new "cruid=" mount option that only governs the uid owner of the credential cache for the mount. Unfortunately, this means that the --legacy-uid option in cifs.upcall was ill-considered and is now useless, but I don't see a better way to deal with this. A patch for the mount.cifs manpage will follow once this patch has been accepted.
