Hi All,
  
    Windows ACL is currently enabled. Firmware version is 3.7.3 Build 20120801  and  QNAP  TS-879U-RP

   Create the following folder structure  \\nas02\Reporting\Operational\Dep1

  Create the Local user group - DepAdmin  and add test1
  Create the Security group -rptadmin add member of depAdmin
 
  
   Add domain users - Read/List folder permission  to Reporting folder and sub foldders
   Add this security  group to dep1 share full access 

  But test1 user cannot write?
