        !            15: This file describes issues associated with accessing a LON-CAPA machine through
        !            16: Samba.  This allows Microsoft machines to mount portions of the LON-CAPA machine
        !            17: as file space (useful for an instructor).

        !            22: Can we sync samba password file space mounting with a kerberos v4 system?
        !            23: The answer is yes-no-maybe so.  It is doable via kerberos v5
        !            24: only with Microsoft Windows 2000.  Samba supports kerberos v4 but requires
        !            25: instructors et al to change their windows settings to send plaintext
        !            26: passwords over the net as opposed to encrypted passwords.
        !            27: Can we even sync samba password file space with unix password file space?
        !            28: ONLY if we script something that crypts both (assume a user has
        !            29: already been added, this script invokes both usermod and smbpasswd...
        !            30: similar to http://adis.on.ca/School-doc/Highschool-HOWTO-1-4.html)
        !            31: so I guess, if instructors want to have samba access be the same
        !            32: as pilot access, they must actually "sign-up" somehow everytime they
        !            33: change their pilot password  :(
