These are normal.  The error crept back in when I merged the Samba3 and
Samba4 code in this area.  The problem is (we think) that some windows
clients negotiate signing of the connection, but actually seal it.  We
have to try one, then the other, but by then the error has been
printed. 

I just need to change the debug level again.
