everytime you create directories using file explorer in Isilon it does that, i always create parent directory and sub directory for Windows shares from a Window machine so that i don't have to deal with root/wheel accounts. I share /ifs directory (as "ifs") and lock it down with share permissions only so that only my storage team has access to it. Then from a windows machine i connect to \\isilon\ifs and create structure like this:  \ifs \data      \nfs      \cifs  under cifs i create sub directories for different departments and share those directly. I do use file explorer to create sub directories under \nfs directory.
I am populating a new cluster with data from an existing Celerra NAS.  I created a new SMB share on the new Isilon and added the proper set of groups I needed for that share. The create went fine. However, in Windows when I look at the security tab for that share, it shows only the generic groups: Everyone, CREATOR OWNER, Administraters (BUILTIN\Administrators) and Users (BUILTIN\Users). It does not show the active directory group I added. I can see that group in the web GUI, and have given it Full access. Why does that group not show on the client PC? Not sure yet if members of that group actually have access.Indivitual users (myself) also do not show up. To make it more confusing, this does not happen on every SMB we created. One from yesterday is OK.
New SMB share permissions does not contain all groups as shown in web GUI
