Hi,
I gone through the link shared by Pete.
It says "Symantec Protection Suite Advanced Business Edition is an "all-in-one" suite that protects critical business assets by securing against today's malicious malware and spam threats as well as by rapidly recovering key systems when problems happen. It is the industry’s first business security suite that combines endpoint, email and data protection with server backup and recovery capabilities"
According to me this suite will be having endpoint as one of offered product.
If suite contains endpoint with Enterprise Edition version then AD integration is possible.
If suite contains endpoint with Small Business Edition version then AD integration won't be possible.
I came across following thread, please go through it as well.

However, please try to get in touch with reseller or Symantec to know what they can offer.
