We have to build a Samba AD, with several DC's.

The designed customer number is about 500 000, or more (user).

The main function of the AD is only the authentication, so there
is a captive portal and some firewall system, user connects to
the network (after auth, with 802.1x), and based on its group
memberships it can use the internet connection.

The spped of each methods (add new user, modify its data, eg.
password, group membership) is no matter. Only the read
capability is important.

But I don't know after the two articles (descibed in my first
e-mail) that should we store in all users in one domain, or we
have to plan that split them to more domains.

And if it needs (to split them), how many objects is the maximum
in an LDB?


Thanks again,


a.
