at least one control permission bit required on acl (dce / sec)

User Action:
Saving an ACL

Meaning:
You cannot save an ACL that cannot be modified later. For some DCE components and applications, only users referred to by entries with control (
c) permission can modify an ACL.

Corrective Action:
Grant some entry c permission on the ACL. This allows users referred to by that entry to control the ACL's contents.
