Welcome to the forums.
I've taken the liberty of deleting your duplicate posts and moving this post to the corresponding forum (Centrify Express).
Account overrides and auto.schema parameters are not available in the Express version of the product.
Are you using Centrify Express or the commercial version of Centrify?
What I don't understand is why you installed DirectAudit; do you also mean to audit sessions?
Note that if you are a commercial customer, you are entitled to product support.
