we are planing to move (nearly) all of our services to the cloud. We have a on-prem Exchange 2010 and Windows Fileserver. We plan to use O365 Exchange.
The only Problem is that we need a on-prem fileserver because we are working with big files at around 20gb. So there is no way to use OneDrive etc. because we only have 20Mbit/s Upload Speed.
Now we have a on-prem AD and we can sync the AD Resources with dirsync to Azure AD. We will have a new Qnap NAS System wich will be the new fileshare. I will join it to the AD to use the AD Users to control the sharing permissions.
Is there a way to get rid of on-prem AD when using a on-prem NAS? I havent found a way to connect a NAS System to Azure AD.
Would be nice to have a solution that the only Hardware we will have on-prem is our NAS for the big Fileshares.
You could, but the challenge would be that you then have two systems to authenticate to - O365/AAD services and then the NAS as it would probably be using local authentication. Realistically things like "save password" make it easier, but it's something you need to factor in from a user experience. If it's a small group of users - it shouldn't be an issue, but bigger groups then it can become one.
