attacks and is required to connect to Windows 2003 servers in their default configuration. This adds an extra field to the SMB header containing the truncated 64-bit MD5 digest of a key (a function of the user's password and the server's authentication challenge), an implicit sequence number, and the message data itself. As signing each message imposes a significant performance penalty, we only enable it if the server will not let us connect without it; this should eventually become an option to mount_smbfs.
