AzureAD-LDAP-wrapper VS IntuneDriveMapping

You could run the AzureAD-LDAP-wrapper docker container on your NAS.

just to be clear I did no mean the way with vpn and ad join I ment this project: https://github.com/ahaenggli/AzureAD-LDAP-wrapper

You could run a tiny VM for AD ($30/mo) in Azure and use a site to site basic SKU ($26/mo) to connect them. It would probably be half the cost of the AD DS at $115/mo. The major downside is now you'd have to run dirsynced accounts with AD as the root, which completely changes the management vs AD DS allows AzureAD to be the root as you're looking for. The only other alternative approach I've seen is something like this LDAP wrapper project: https://github.com/ahaenggli/AzureAD-LDAP-wrapper. I have not tested it yet, and it's less secure. Here's my two cents, if you have a limited group of users where the $115/mo is too expensive, use local accounts. If it's a more significant user group, eat the $115/mo, it's necessary.

Currently, each user has a (local) Synology account. For the pilot, we've been using the Intune Drive Mapping Generator tool to create a PowerShell script to deploy the mapped drives. As an initial test, we've been manually adding each user's Synology credentials to Windows Credential Manager on their machine. This would probably be "fine" for us if not for the shared PCs; we'd like for users to sign into any shared PC and auto-magically have all their shares mapped and authenticated, ready for use.

Intune Drive Mapping Generator

I am currently hybrid environment with AADJ only devices. For my users on AADJ devices I used Intune Drive Mapping Generator by Nicola Suter. I don't have any user folders mapped but maybe you could use a system variable like %USERNAME% to map their folders. Otherwise this worked great for our common file shares.

I think this is exactly what you are searching for: https://intunedrivemapping.azurewebsites.net/

This script performs network drive mappings with PowerShell and is auto generated by the intune-drive-mapping-generator ([https://intunedrivemapping.azurewebsites.net](https://intunedrivemapping.azurewebsites.net)). When executed under SYSTEM authority a scheduled task is created to ensure recurring script execution on each user logon.

Just wondering what's this Intune mapping generator here do differently to creating a regular powershell script for mapping drives?

Did you use this script? https://intunedrivemapping.azurewebsites.net/
