No the source is not Auth source , its a simple source for which we have to certify uncorrelated accounts with specific entitlement and only Active uncorrelated accounts need to certify .
I am assuming you are using Uncorrelated Accounts Certification Campaign option that is available from Search section and selecting only ONE source in the campaign.
Based on this, I suggest using below logic:
You want to Include based on Condition 1ANDCondition 2
Instead use Exclude based on NOT Condition 1ORNOT Condition 2
So, create an Exclusion filter with following conditions: EntitlementDoes Not EqualCustomer Approval Manager Account AttributeActiveDoes Not EqualYes
