I have always, in my ignorance of the protocols, wonder this; on a
setup where the passwords are only checked against the smbpasswd file
and not "transmitted" to any other servers etc, is it not possible to
support a backdoor use of the UNIX crypt format ? Even if it is down
to using the crypt()'ed string as the password for samba and then just
doing final, local comparisons.

I can understand where integration with an NT domain with real M$
servers would make this impossible, but where I (or others) want
to run samba as the *only* servers is this sort of thing even
feasible (let alone desirable) ?
