Features, Office Everyone knows that Microsoft Exchange is expensive - but ubiquitous " and plenty of open source projects and vendors have been trying a variety of technical approaches to replace it. While none is yet a drop-in replacement, a PC World article looks at ways that some administrators can get a cost advantage by switching.

PostPath for Exchange server.

http://www.linux.com/feature/146451
"from the network and Windows PC's viewpoint, PostPath actually appears to be an Exchange server."

Maybe OpenChange will get there also, but it hasn't announced a release yet.

Samba and CUPs for file and print servers.

Just to clarify something mentioned in the parent..

Likewise is *not* a replacement, it actually brings your non-Windows systems *into* Active Directory. The free version is very limited, it is not much more than an automation for samba+keberos+pam+nsswitch setup tasks, which is nice.. until it breaks..

If I decide to join a Linux box to AD, I usually just do it manually.. or if the customer insists, I set it up using NIS/NIS+ & AD.

Just to clarify your clarification ... wouldn't it be possible to use Samba 4 as the replacement for Active Directory, and in addition use Likewise to manage it?

That's good, but there are several problems:

1) Lots of vendors

2) probably poor support - you might have to pay for Microsoft support, but it is VERY good

3) lots of different applications from different vendors will almost certainly lead to it being a biatch to maintain.

Far easier to use one vendor imho.
