Group mapping, but with OU exclusion

I want to add users to an AD group except users in a specific OU.

Any ideas on how that should be worded?

In the group mapping expression, you can add an expression that specifically states to exclude where users are in a specific container.

Please try something like this:

Employment.EmployeeStatusCode == "A" && User.Container != "OU=Test,OU=Users"

Works great! Thank you!
