Need help understanding permissions please

[Pandamonium]

Hi All,

I have tried several times to get my head around user/group permissions but I clearly don't get it yet. Could someone please help me out with an idiots guide relevant to my situation? My entire background has been on Windows systems so I have no problem there, but when I add in Linux permissions I get lost.

I have a windows (SMB) share which I need to be able to set windows user permissions on (so far so good). I also then need to setup permissions so that Syncthing can replicate the contents of this share for me. I thought I had it working some time ago, but I then realised that some users couldn't access the Windows share as I wanted. I've now fixed that, but seem to have broken the Syncthing access.

Also, I have a further Windows share that holds my media. This also needs access via Linux users but the only way I have been able to get this to work is to pretty much give everyone access to everything, which I realise is not the way to go.

I would really like to understand what I should do here to mix the two permission types if someone can explain it in simple terms please. I've read loads of posts across the internet some of which just seem to conflict each other so I'm more confused now than when I started

Many Thanks

Take a look at this. However it's not a good idea mixing permission types.

So I am trying to replicate the process shown in the first video and I've noticed a possible problem. When I create the SMB share and assign the group to it, it doesn't resolve when I view the folder permissions under Windows. Following his steps exactly, I end up with the Everyone showing as Read only, a group called FREENAS\MyDomain (my freenas server is named freenas) which has full control and a user that remains as a guid. I don't see my shared group anywhere.

I have a proper windows domain and the freenas server is joined to.

Any ideas why I'm not seeing the freenas group against the folder?

Update - so I've just realised the GUID that doesn't resolve is probably the group I created in Freenas (even though the icon shows as a user - probably as it cant resolve and so doesn't know if its a user or a group), so I guess the question is isn't my new freenas group resolving under windows?

Thanks
