I've searched extensively, and this seems to be the case. Credential files don't seem to be an adequate solution, as they are still clear-text. Booting from a CD, one can still open any Hex editor and read the .credentials file in clear text.
Someone mentioned that this is moot since the password is sent in clear-text anyway; I don't believe that's true, however.
Is there some other secure solution (perhaps not even CIFS based) that admins use?
