The GetAccessControlTemplatesOnObj
method returns ACT_LIST when TCTXT or RESOURCE is specified, even
if there are no ACTs (an empty list is returned).
When TCTXT is specified
and previous calls to the ApplyACTToObj or RemoveACTFromObj method
on this TCTXT modified the list of ACTs protecting the resource, then
the modified list is returned. Until the EndTransactionContext method
is executed on the TCTXT with SECAD_COMMIT_TC, the content of ACT_LIST
might not reflect the actual ACTs currently protecting the resource.
When RESOURCE is specified
in the GetAccessControlTemplatesOnObj method, then ACT_LIST returns
the actual ACTs protecting the resource.
