You can also put the `access_by_lua_file` directive in a `server{}` scope if you want to protect only a vhost.
SSOwat configuration
--------------------
```
nano /etc/ssowat/conf.json
```
If you use YunoHost, you may want to edit the `/etc/ssowat/conf.json.persistent` file, since the `/etc/ssowat/conf.json` will often be overwritten.
