Hi,
Recently we moved from onprem Windows AD to fully cloud. (Entra ID)
Earlier we used windows AD with radius to authenticate L2TP users with mikrotik router to access internal resources from outside.
As we do not use the on prem AD now, I need to find a proper solution to authenticate the Entra ID users to access the VPN (L2TP) with miktrotik.
Thanks

I assume you’re talking about a radius connection to NPS. If you dont already have it, just set up a tunnel to your Azure AD - oh, sorry, I meant Entra ID! 
Btw, I honestly can’t stand these pointless brand renames..
