Hey,

I have two processes, test.pl and proc.pl. test.pl runs with elevated rights (as administrator), the other runs as a restricted normal user. They have a common folder in which test.pl creates a file name lock.tmp. Then it will have such permissions that proc.pl won't be able to read it, let alone its attributes or modification time. The last one is the most important, I would like to get the modification time (for this purpose I use GetFileTime from Win32API::File::Time) from proc.pl. A great solution to this problem is to change the owner of lock.tmp to the virtual user Everyone and grant full access. This needs to be done from perl, I can't and won't use command line tools. What I found is Win32::Perms. I wrote a few lines using this package to remove all permissions first. 
use Win32::Perms;
my $file = new Win32::Perms('lock.tmp');
$file->Remove(-1);
$file->Set();
$file->Close();

This is the point I stuck. I would like to add the special user Everyone and grant full access. Sometimes $dir->Add( { Account => NULL, Mask => FULL ); does it, sometimes not, but I think this last piece of code is nasty. Everyone is tricky because its name is something else on different translations of Windows. My script should run even on these as well. There should be some special and unique ID for Everyone in Windows, because if I bring a file within an archive, from a translated Windows to a non-translated one, it's still Everyone (however it's written in the language that Windows was translated to). Is there any way of setting the owner of a file/directory without specifying the owner's name?

I don't insist on Win32::Perms. If there's another neat Win32 package that could have the job done, also great for me. Nevertheless it would be also a good solution if I could force perl to create every file and folder with this permission mask (similarly to umask in UNIX).

Thanks in advance
