The linux client doesn't seem to mind, but the Solaris client (reasonably enough) is giving up; the symptom is a "security mode does not match" error on mount. We could modify the export-parsing code to ensure the secinfo array is nonzero. But I think it's slightly simpler to handle this default case in the implementation of the MOUNT call. This is more-or-less the same thing the kernel does when mountd passes it an export without any security flavors specified. Thanks to Tom Haynes for bug report and diagnosis. Signed-off-by: J.
