Been using the latest release version of OMV on a raspberry pi.
I decided to try using Apple Filing instead of Samba (mostly because Samba never seems to be very stable...try to copy too much at once and it invariably crashes). I created two shares and two users (myself and my wife) . Read/Write permissions have been granted for both of us for both shares. Went into the shares and set the ACL the same way on both. I even created a group and joined both of us to it and gave the group the same read/write permissions. problem is that I can see both shares and she can only see one. I turned on Samba and tried that and we both can access both shares. Tried FTP and got the same result...both users have access.
As far as I can see the two shares are set up identically, although they are each on a separate file system/drive.
I am out of ideas as to what is wrong. I have even tried setting her as the owner of the share. Same result, I can see it, she cannot.
