Rancid integration with LibreNMS

Hi there,
I’m trying to integrate an existing Rancid installation with LibreNMS. As Rancid was already there I couldn’t set it up as was described in the LibreNMS docu (different svn).
From what I found I tried this in the LibreNMS config:

#$config[‘rancid_configs’[‘NetworkDevices’] = ‘/var/lib/rancid/NetworkDevices’;
#$config[‘rancid_repo_type’] = ‘svn’;
#$config[‘rancid_ignorecomments’] = 0;

LibreNMS added some devices to the router.db that weren’t there before (okay so far) but I don’t get any Config tabs for the devices included in Rancid in the LibreNMS GUI.
Any ideas why?
