I did not make that assertion.  I however do assert that any solution
that relies on plaintext passwords is flawed, insecure and buggy.  

There are a large number of know issues (starting with the need to patch
the clients, but much worse than that) with plaintext CIFS
authentication.  Fundamentally, it is untested by Microsoft, with all
that implies.

I'm not sure where this fits in, but the point is moot.

I am warning other users that that solution you suggest is not stable,
reliable nor long-term functional.  It requires explicitly disabling
Microsoft's own security policies, and cannot be used in a PDC setting.

We are waiting for Novell to fix their product.  There is little we can
do until they do that.   (We rely on certain RFC-specified behaviour in
order to perform certain atomic updates).

I wish you luck, but strongly warn you to keep a very close eye on your
system's stability, particularly in relation to network drop-outs.
