Well if you don't need a AD it's kinda pointless to set one up or pay for one.
SSO is also kinda dangerous anyways, security-wise, anyways. Ya kerberos lowers the risk of people spoofing domain names and sniffing passwords and such, but so does having a switched network with firewalls. If you have a single server that is responsable for all authentication everywere and if that server gets rooted then the whole orginization is wide open. Also in terms of hosts it doesn't realy improve things to much since they are still vunerable to keyloggers and such. Basicly having a bunch of different passwords for everything compartmentalizes everything so it would help to slow a hacker down.
(this isn't something against AD or anything, you'd have the same problem going with Novell directory services or Linux with Kerberos/LDAP or Linux with Samba)
It all depends on the circumstances of course. The ability to control and manage users and their passwords from a central location can improve security quite a bit if you have to manage a few hundred users versus a couple dozen.
And with only Windows clients, the features that Windows 2003 offers just as a file server (shadow copies being a huge one with Access-based Enumeration being a minor point) would justify sticking with it.
Linux offers significant benifits as a file server itself...
Tack on Exchange, and I couldn't imagine moving away from SBS (not that I use SBS, rather just full blown Win Ent + Exchange).
Exchange is a kinda of a pain in the rear. It's ok if your going Microsoft-everything, but I think that it's difficult to deal with in a mixed enviroment. It practically only supports one specific client on only a couple specific operating systems. Most of it's features are pointless to most people and it can get expensive.
Not that I recommend abandoning it if your using it.. that's much worse a lot of the times.
Now going with a Windows with AD and Exchange and all that makes a lot of sense to a lot of people. But I don't think it's best for every situation.
One big thing were avoiding Exchange and whatnot is if you want to run a mixed enviroment at anytime in the future. Microsoft software generally doesn't integrate well with software from other vendors... especially competing software. There is a lot of lock-in.
For instance if you ever want to run Linux clients in the future that would be very difficult to make work well with Exchange. You have Exchange plugin with Evolution and such, but it's not a ideal solution.
That's just my 2 cents on the issue. If your a big orginization though and depend on Exchange and AD heavily already then it seems to me moving to a Linux solution wholesale would still be a nightmare.
Going to have to look into that. We currently use Outlook as well, I found Scalix (
www.scalix.com) and it looks fairly promising.
cool. Although I have no experiance with it some people have said that Kolab seems pretty promising.

They are KDE centric it seems like it and it is suppose to integrate well with the KDE groupware stuff. Also they have connector clients for Outlook. And probably with Thunderbird and such in the future.
