Once an override Access Control List (ACL) has been applied, it can be edited or overridden by another override.
For example, assume that a folder has an override ACL that was assigned by a lifecycle state. The user can view the override and modify it by changing the entries in the list and/or by modifying the permissions of the access control entries.
You can also access the Details dialog by selecting Details from the File menu.
Rule: There can never be more than one override ACL on any Vault object and the last override ACL is always used, regardless of whether the override was manually applied or applied by a lifecycle state.
