This "asumption" of Andrew is in my opinion wrong.
I hope he did mean or : DOMAIN\Administrators or ( which is the same as ) BUILTIN\Administrators
But no DOMAIN\Domain Admins is used on sysvol in "FILE/SHARE" rights.
"Domain admins" is member of the above group BUILTIN\Administrators and inherits it rights.
The "FILE/FOLDER" rights on a normal windows server,
run : icacls c:\Windows\SYSVOL which shows.
NT AUTHORITY\Authenticated Users:(RX)
NT AUTHORITY\Authenticated Users:(OI)(CI)(IO)(GR,GE)
Primary it involves these SID's where the samba problem is as far i know.
( looks about the same as : https://bugzilla.samba.org/show_bug.cgi?id=13532 )
Where, what, is set by default?
And when you look at the "Linked GPO's" within the AD, there, it shows other rights.
The Default Domain Policy with a GPO editor, it shows for example.
Domain Admins ( DOMAIN\Domain Admins )
Enterprise Admins ( DOMAIN\Enterprise Admins)
(looks about the same as : https://bugzilla.samba.org/show_bug.cgi?id=12236)
Beware of the misunderstanding of the
- share rights on sysvol
- file/folder rights in sysvol
- The sysvol rights with the AD.
( looks about the same as : https://bugzilla.samba.org/show_bug.cgi?id=11757 )
This is why i use my script to set "correct" rights in samba sysvol and netlogon.
Which set the windows 2008R2 rights, which i took from my 2008R2 server.
Let hope this info give someone a great idea ;-)
I suggest also, ask Rowland, we discused this already a lot on the samba list.
I know he made some patches for the GPO rights fix also, but i cant find that back in the bugzilla list.
