VCSA 6.5, vsphere client and Active Directory

I am planning to replace a vCenter 5.5 based on a Windows machine with a VCSA 6.5 VM.

Let me ask for two clarification:

• Can the VCSA 6.5 VM be member of an Active Directory domain? I would say "Yes", but I would like to get a confirmation from experts...
• Can users access the VCSA based vCenter with the "good old" vSphere client, at least for basic tasks?
