Hi Andrew, in which case, I think you better help this guy:


It looks like Samba may have already have broken classic domains.

I am not saying we should just announce that Samba no longer supports
classic domains. Samba should accept that keeping them working is
taking emphasis away from the core work of making AD better and as
such, Samba should announce that Classic domains are deprecated and
state a date when Samba will no longer support them.

It is not as if there isn't an upgrade path, but some people will not
upgrade unless you force them.
