open source Solution for Active Directory Services

["satyashil rane" <satyashil.rane@gmail.com>]

Dear all,

I want to know the open source solution for Windows Active directory  Services (ADS).
My
primary Goal is to set up a Linux box having Directory where all other
mix of Windows and Linux client will join to this domain. Most of the
client machines would be windows xp.

I have already googled for this requirement and understood
that it can be done with Open LDAP and Samba, but I would love here the
experience of the people who have already implemented this solution.

Can someone please suggest me a open source solution or detailed document to how to go about?

Thanks in advance.

Best regards

Satya
