[Samba] Migration (upgrade?) from 2.4 -> 3.0.x

[Ken D'Ambrosio]

Hello, all.  I'm planning on moving my primary (PDC) server from 2.4.x 
to 3.0.x next month.  I've read the 3.0.x docs regarding this 
(specifically, chapter 30 of the HOWTO), but, while they explain a lot 
of the stuff that's changed, they don't actually explain what gotchyas, 
if any, might be lurking.  So, a few quick questions:

- Will there be any potential SID issues?  If so, how do I ensure 
avoiding them?
- Does anyone know if the stock Debian 3.0.x package supports ACLs?
- Does anyone know if the stock Debian 3.0.x package supports PAM?
  [In both of the above cases, the Debian 2.4.x package didn't, so I had 
to hand-compile.]
- Is there anything else I might have overlooked that someone else has 
been bitten by?

Thanks much,
