External Radius Server Integration

[asad-vathare]

Hey,
My company is trying to use openwisp as the main service to manage our devices, and we are trying to integrate external freeradius server to openwisp, so we can use openwisp as single interface to manage our devices.
So, we went with connecting external freeradius instead of openwisp_radius due to scalability and availability issues we want to prepare for.

We have tried couple of things on our own. like

1. Connecting same database to openwisp and freeradius.
2. Creating database with freeradius schema first and then ran migrate command to create tables for other modules except openwisp_radius (which we --fake 'd), then manually created remaining columns and tables in mysql
3. We are using openwisp server as freeradius proxy

we tried all this, and we are facing schema mismatch issues where freeradius is using different schema than openwisp, and it seems that they aren't compatible. But the documentation suggested that there is a way to connect external freeradius server to openwisp, and we want some help setting it up.
Any documentation is appreciated, Thank you.
