ACS ISE feature Parity question

[nadeekha]

Hi Experts,

I have been looking into feature parity between ACS and ISE for my customer and have seen in the comparison documentation the below feature. As per the doc this is available in ACS but not ISE. I have a hunch that this might mean being able to specify a specific AD DC for authentication purposes but am not clear exactly what the below means. Can any one please explain?

AD Server specification per ACS/ISE instance

Yes

No

Thanks

ISE can join multiple active directories out of the box, so this feature is not needed.

I believe this feature in ACS allows different ACS nodes to join different active directories.

We have an ACS vs ISE Comparison document which says this is not applicable for ISE.

It would help to know what scenario the customer is concerned about and we could help answer how to solve that problem.
