Need a report that lists groups with a disabled user account in managedBy field

I need a report that lists any type of group with a deprovisoned user account assigned to the managedBy field. We have processes that depend on the user account assigned to the managedBy field of a group being enabled. I have played around with some of the built in reports and have got pretty close to what I need but the data generated is not quite accurate. The report would be based off of the user account being assigned to the manageBy field while in a disabled status
