Greetings!
I am in the process of deploying ServiceNow in our company. I wish to import ADDM data into our CMDB and wish to integrate AD authentication. It does appear that using MID servers are the secure and correct way to do this. Ideally, I plan on building these MID Servers on VMware guests, and clustering the MID servers. What I don't know is: Do I want one MID server per guest with multiple capabilities configured or multiple MID server instances with one capability per instance.

The only reason you would need more than 1 MID server for this is if they all couldn't be reached on the network via a single MID server. Concern for redundancy or load on a single MID server might also be concerns but I wouldn't imagine needing any more than 2 in that scenario anyway.
It's also worth noting that the MID server can help to pull in data, but it's not something you would use to facilitate authentication.

Hi Mark!
Yes, I have read the wiki articles describing setup of MID Server and AD integration, and do have a handle on this.
I do want high availability so I will require at least 2 MID servers for production.
What I am unclear on is the following:
If I have 2 MID servers in a load balanced configuration and I want to use these MID servers with 2 capabilities...(AD Authentication and ADDM integration), do I want to have one instance of MID running on each server with 2 capabilities or do I want 2 instances of MID running on each server configured for one capability per instance?

That's the thing, you won't use the MID server for AD authentication at all. You'll only use it for your data import.

Hi Mark!
I do get this. Perhaps I stated my question in a confusing manner. In this wiki AD integration, is well documented making use of a MID server for the data imports and such. This I think I have a handle on.
But I want the MID servers to facilitate two different capabilities. Importation of AD data and importation of ADDM data.
That is pretty much where I am unclear on what I should do and what is best practice.
