<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">We\u2019ve been using nfs4_get/setfacl to manage nfs4 acls as an alternative to the mm commands for a few months. It mostly works pretty well \u2013 in particular it\u2019s simple to set permissions with inheritance flags recursively on a directory structure
and it\u2019s easy to add an ace for a user/group without affecting existing permissions.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">We\u2019ve noticed though that when permissions have been changed via SMB they get these DACL ACL flags set:<u></u><u></u></p>

<p class="MsoNormal">Background: It\u2019s an ESS5000. Client access is via a remote mount to an HPC system, a large number of Windows/Mac/few Linux SMB clients and a handful of NFS (4) clients via CES. We\u2019re on 5.1.9, although the cluster and fs versions are a
bit behind. -k is nfs4.<u></u><u></u></p>
