Subject: No support for ACLs on network shares? Message-ID: <5652E58A.2030605@codespunk.com> Date: Mon, 23 Nov 2015 02:08:10 -0800 User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:38.0) Gecko/20100101 Thunderbird/38.3.0 MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: 7bit I noticed today that when accessing a network share, the permissions for the current user are not resolving. For example, I'm connected to a network share //server/share which is a CentOS share with a unix login/password. The share is already logged in by Windows and on the keychain so I don't have to enter the login information. In Cygwin, 'cd //server/share' then 'ls -l' I get this: drwxrwx--- 1 Unknown+User Unix_Group+1001 0 Nov 23 2015 test I'm already logged in through windows as the 'Unknown+User' but Cygwin does not recognize that I have access to any of the ACLs for the owner or groups and also does not resolve the SID name. The problem with this is that files created or modified are only done so in the 'Everyone' permission and inherited permissions such as the execute bit are not recognized. My use-case is where I've mapped a network path to either a network drive or a symlinked folder (with Windows mklink) with the path on the environment's PATH. In this case, files which are executable are not recognized and do not appear when calling 'which'. It seems as though Cygwin only maps ACLs to the SIDs stored in passwd and group and cannot handle ACLs when accessing network devices where SIDs are not present in these files. Running passwd/mkgroup after the share is on the keychain does not provide additional SIDs. Is there no support for ACLs across network shares at all?
