Hi,

I'm assuming that you have ACS version 4.x. Please go through the attached document for ACS and AD integration. In case you have ACS version 5.x then please let me know, I'll send you steps for that as well.

Regards,

JK

If you could provide the 5.x doc for me I would appreciate it.

If you just grab the 5.x user guide from CCO (which is found by a quick search):

Joseph,

There is no specific document for ACS 5.x out yet. However, below listed links covers everything whatever you needed.

Joining ACS to an AD Domain

ACS 5.1 has to be configured with a valid NTP server for time synchronization, preferably from where the domain controller is syncing its time. Another one is a valid DNS server which can resolve internal  names.

Both of them will be configured from the CLI:
