Hello,
When using krb5 exports, I noticed that TIRPC does not send XID in response
- see xdr_reply_encode() for MSG_DENIED case. Looks like Linux clients
can't decode the message and go in to an infinite loop retrying the same
NFS operation. I tried adding XID back (like it is done for normal case)
and it seems to have fixed the problem. Is this the right thing to do?
