### Grafana Configuration Considerations
Make sure in your configuration that `root_url` is set correctly, otherwise your redirect url might get processed incorrectly. For example, if your grafana instance is running on the default configuration and is accesible behind a reverse proxy at `https://grafana.company`, your redirect url will end up looking like this, `https://grafana.company:3000`.
If you get `user does not belong to org` error when trying to log into grafana for the first time via OAuth, check if you have an organization with the ID of `1`, if not, then you have to add the following to your grafana config:
```ini
[users]
auto_assign_org = true
auto_assign_org_id = <id-of-your-default-organization>
```
