+ depends on CIFS
+ help
+ Modern CIFS servers including Samba and most Windows versions
+ (since 1997) support stronger NTLM (and even NTLMv2 and Kerberos)
+ security mechanisms. These hash the password more securely
+ than the mechanisms used in the older LANMAN version of the
+ SMB protocol needed to establish sessions with old SMB servers.
+
+ Enabling this option allows the cifs module to mount to older
+ LANMAN based servers such as OS/2 and Windows 95, but such
+ mounts may be less secure than mounts using NTLM or more recent
+ security mechanisms if you are on a public network. Unless you
+ have a need to access old SMB servers (and are on a private
+ network) you probably want to say N. Even if this support
+ is enabled in the kernel build, they will not be used
+ automatically. At runtime LANMAN mounts are disabled but
+ can be set to required (or optional) either in
+ /proc/fs/cifs (see fs/cifs/README for more detail) or via an
+ option on the mount command. This support is disabled by
+ default in order to reduce the possibility of a downgrade
