Is there an automated way to traverse a filesystem and remove any ACL entries that reference invalid SIDs in any version of Windows with NTFS?
Maybe it's because I am running this on a 2003 server, but this does not produce useful results for me.
I'm not sure what that is supposed to do, but it doesn't provide anything useful for me. I have a folder with an unknown SID.
returns the ACL entries, including "No mapping between account names and security IDs was done". It does not tell me which SID it failed to get a mapping for.
All this tells me is: "Successfully processed 1 files; Failed processing 0 files". Sounds great, but what was the result of the processing?
I get the exact same results running this on any individual files in the folder as well. In order to remove the SIDs, you need to know what they are. And this is not a very helpful method for getting a list of the SIDs that need to be cleaned up.
icacls can do that:
ICACLS name [/grant[:r] Sid:perm[...]] [/deny Sid:perm [...]] [/remove[:g|:d]] Sid[...]] [/T] [/C] [/L] [/Q] [/setintegritylevel Level:policy[...]]
You can also check for bad entries:
