Systematization of identification databases?

Question

Database

Hello!
You need to make a common database for authentication:
1.In the Web interface
2.In ActiveDirectory Domains
3.In OpenVPN
4.In SSH, L2TP, MSSSTP 5.In
Minecraft Java Edition
6.In Minecraft Bedrock Edition
7.In CS:GO
How can this be implemented and what databases to use?! The scenario is something like this: there is a "Register" button in the web-face, after the registration procedure the user receives user access rights to all of the above resources, while you can manage the rights of the created users! If the user is created in ActiveDirectory Users and Computers, then he also gets user access to all the listed resources! If the user is created in other resources, then he gets access ONLY to them!
Please help!
Many thanks in advance for your replies!!!
