How to set MACL from one directory to another? [Ravi Krishnaswamy]
A correct way to do this will be as follows:
// Get DirectorySecurity from source directory
DirectorySecurity dsSrc = Directory.GetAccessControl(srcPath, AccessControlSections.Access);
// Transfer ACL security descriptor
byte[] sdBinary = dsSrc.GetSecurityDescriptorBinaryForm();
DirectorySecurity dsDst = new DirectorySecurity();
dsDst.SetSecurityDescriptorBinaryForm(sdBinary, AccessControlSections.Access);
// Set new DirectorySecurity to destination directory
Directory.SetAccessControl(dstPath, dsDst); //Destination
