The SMB encryption scheme never sends the - cleartext password over the network but it does store the 16 byte - hashed values on disk. This is also bad. Why? Because the 16 byte hashed - values are a "password equivalent". You cannot derive the user's - password from them, but they could potentially be used in a modified - client to gain access to a server. This would require considerable - technical knowledge on behalf of the attacker but is perfectly possible. - You should thus treat the smbpasswd file as though it contained the - cleartext passwords of all your users.
