I'll believe it. I'm a newbie at Samba - but as Craig has pointed out,
and for the same reasons, the methods used by IDEALX and repeated in the
official Samba doco and Coupeau's "HOWTO" were screwing up my ldapsam DB
and uglifying my servers. There had to be a better way, and both Craig and
I discovered that independently of one another. Actually, I find it
marvelous that it works :)

What is achieved works, and that's the best that can be said about it.
However, it's totally unnecessary and can easily be avoided.
Furthermore, whatever one does, SWAT (which I don't normally use - apart
form reading about the defaults) makes a complete mess of groups with
spaces in them.

That is not so. An alternative solution is available with Samba 3.0.7 thru
3.0.11. Both Craig and I have posted (this thread) what that method is.
However, it makes use of the IDEALX scripts impossible.

Gestapo in Open Source? Wouldn't that rather be Posix, many years ago (in
an attempt to clean up a diversity of alternative systems)? Red Hat
(Linux) accepts both, but they are *ugly* and lead to all sorts of
complications. IIRC SCO Openserver 5 accepted neither.

I have no problems with either?

It really has nothing to do with the gestapo, maybe a bit of history
reading wouldn't come amiss?

That is not so. The solution lies for the hand and is already present in
the current code. Craig and I both implement it ;)
Best,
