smb_mount: mount failed to ubuntu/share :syserr = Broken pipe

macbook:/$ ps -A | grep NetAuth
2028 ?? 0:11.22 /System/Library/CoreServices/NetAuthAgent.app/Contents/MacOS/NetAuthAgent
11282 ttys000 0:00.00 grep NetAuth
macbook:/System/Library/CoreServices$ kill -9 2028

After killing the NetAuthAgent application, everything works well again:
