FILEACL is an win32 console
free software by Whats new : 2.8.0.3
New inheritance handling to mimic Windows UI Here are its features: · View ACLs on any NTFS local or remote drive · Set ACLs on any NTFS local or remote · View Ownership · Change Ownership · Uses Backup and Restore Rights to view/change ACL/ownership on non accessible files/dir · recurse through files and directories · [WIN2K] Inheritance auto-propogation aware · shows RAW SID and/or Access Mask for an ACE · Apply RAW SID and/or Access Mask (you could put ACL related to non-available domain trustees !) · Address Deny rights · Treats ALL inheritance matters of NTFS (unlike Windows NT 4.0 GUI) · Batch Mode to dump permissions to a file and reapply later (/BATCH) This utility in especially valuable with NT 4.0 because ACLs are not addressed completely by neither the GUI nor CACLS nor XCACLS. Windows 2000 ACL GUI editor is much much better, but this tool can still allow you to automate ACLs checking/enforcing/recovering.. With W2K you also can use ADSI to deal with ACLs. You could use it for (I use it for) : · Dumping (saving) ACLs on large network shares · Modifiy the resultant text file and restore it · Accessing/viewing/modifying ACLs on Quota-locked directories. · Change Ownership on dir/files · Apply complex ACLs (complex Mask or complex inheritance scheme) · debugging ACLs
Command Line : fileacl<File/Directory> [/{S|G|R|T|O|D}
{trustee}:[[!]RWXDOPF][/[!]RWXDOPF][/[!]RWXDOPF] [options] or fileacl<File/Directory>
[/{S|G|R|T|O|D}
{trustee}:[RWXDOPF] [:IO|OI|NP|CI|FO|F|FF|FSF|FS|SFF|SF [options] commands:
Trustee could be user or group, domain\trustee or SID (S-1-x ....). Simple Rights
Switches:
New ! FILEACL use a more accurate inheritance scheme and allow for
"apply toobjects and sub-folders in this folder only" Ex: FILEACL c:\temp\testacl /s user:R/!W/F will limit inheritance of Write access for files to the testacl directory. You also can use a different syntax adding your inheritance flag manually at the end of a single mask command line. Inheritance can be :
FILEACL c:\temp\testacl /s user:R/!W/F Error Codes:
Typical : FILEACL d:\temp\acltest /S user1:RW gives Read/Write access on directory d:\temp\acltest to trustee user1
FILEACL \\server\share\dir /S admingroup1:F /S usergroup1:RX/W/D /O admingroup1 /SUB:3 /FILES give admingroup1 Full right to network dir, and give usergroup1 RX to dir; right to modify existing files to dir, and delete files on 3 sub-levels of directories and files. admingroup1 is set as owner for all files and dirs
FILEACL \\server\share\dir /S S-1-5-21-1606980848-1383384898-842925246-1008:R give Read right to a user given its SID, even if the DC for that domain is not online or the account is not created/synchronized yet ! or even : FILEACL \\server\share\dir /S S-1-5-21-1606980848-1383384898-842925246-1008:0x120089/0x100116 to set a special mask
FILEACL d:\temp\acltest /INHERIT /REPLACE Reset permissions and allow propagation from upper levels
FILEACL d:\temp\acltest /owner /raw gives ACEs (one trustee per line) and owner with RAW sid and access mask
What are ACL and ACE ? ACE stands for Access control entry, it specifies : · a trustee · an access mask · an ACE type (could be deny ACE, audit ACE) · an inheritance flag ACL stands for Access control List, it is a list of ACEs.
What does ACLs levels means ? Multi-level ACLs treat inheritance (ONLY for directories !) If you see/give one
level ACL is built with RW rights for the directory, and all inherited files and sub-directories.
If you see/give two levels of
ACE ACL is built with RW rights for the directory and all inherited sub-directories, and X right for all inherited
If you see/give three levels
of ACE ACL is built with RW rights for the directory, X right for inheriting files and R right for inheriting sub-directories.
Difference between OSes NT4 SP3, NT4 SP4 and later and Windows 2000 treats ACLs in a slightly different manner :
NT4 SP3 uses GENERIC_RIGHTS (ie 0x10000000 to 0x80000000 access masks) to grant access to files and inherited files.
NT4 SP4 and later do not use GENERIC_RIGHTS any more (although it understands it), it uses the same masks for directories and files masks.
On directories NT4 (All sps) always build a 2 ACEs ACL for a trustee, First ACE is set with Directory Inherit flag (0x2). Second ACE is set with Files inherit only flag (0x9). This means that the first ACE addresses the directory and its inherited sub-directories, and the second ACE addresses only inherited files. In only one case does NT4 build a single ACE ACL for a trustee : When you select "Take ownership" for a directory, it deletes the ACL and replace it with a 0x3 ACE (Inherit on files and directories).
Windows 2000 is much more consistent about all that : it only create separate ACE if needed, each time a single ACE can be used, it is.
Differences in Access Masks : Windows 2000 does not need READ_CONTROL (0x20000) mask for writing to a directory and NT4 does need it. A Write ACE would typically be (0x120116) with NT4 and (0x100116) with Windows 2000, be sure to use /NT4 switch if your ACLs will be read by NT 4.0 workstation .
Windows 2000 introduce "Delete file and subfolder" right (0x110040).
Windows 2000 has an Autopropagation feature, all rights on a parent are propagated on children. FILEACL keeps the protection status of a folder unless /PROTECT or /INHERIT Go Windows 2000 now !
Questions ? : gbordier@gbordier.com or g_bordier@hotmail.com OUTPUT :
Minimum Access for reading a file is Rr on parent dir and RrRep on file Access masks are defined this way :
GR = Generic Read GW = Generic Write GE = Generic Execute GA = Generic All AS = Access to Audit ACL
(SACL) Known Issues : RWXDDc (every right except ownership and write permissions) may appear as
