Active directory configuration for Afaria server environment

Hi,

I am not from system administration background & i am trying to configure the Afaria 6.6 for iOS device. Please help me understand this that is it really needed to configure active directory services(windows server 2003) for this as CA server configuration is needed for iOS provisioning server. Is CA server acting as standalone active directory server is fine to provision iOS devices.

Please suggest.

Regards,

Shrikant.
