Title

The "Enable computer and user accounts to be trusted for delegation" user right must not be assigned to any groups or accounts on member servers. (Cat II impact)

Discussion

The "Enable computer and user accounts to be trusted for delegation" user right allows the "Trusted for Delegation" setting to be changed. This could allow unauthorized users to impersonate other users.
