Hi, Everyone

I am a sales. One of my customer have 300 Windows XP/7 machines.
And, he is looking for the way to centralized management user account, without real Windows AD.
Can OES11/DSfW play a role like Windows AD and allow Windows XP/7 workstation joint the domain and centralized manage the user account? (Customer don't want Windows AD server in the network. They want linux.)

Am I correct to say? There are 3 options to achieve customer goal.
1. SLES Sambe
2. OES11 DSfW
3. ZENworks Configuration Management, Dynamic Local User

Please advice.
