Unable to log in since auth change

Help
1

Since the recent auth change I’ve been unable to log in to our LibreNMS installation. My issue is very similar to this one in that I’m using a https://… base_url, but with one key difference; I am not using a reverse proxy. I am running apache with SSL configured, and everything was working prior to the recent auth update.

I can access the login page, but with a “mixed content” warning. Additionally, when entering the username/password Firefox warns that the forms are not being submitted over a secure channel, and even if I ignore this it does not log me in, it just kicks me back to the login screen. The logs show nothing (beyond the normal polling).

validate.php output:

Let me know if you need any additional data.

Can you post the mixed content? What are being loaded as http instead of https?

Also, try login with /debug=yes/ in the url (Access https://yourserver/debug=yes/ and the try to login) and check librenms.log

The logo is being delivered over http instead of https (http://…/images/librenms_logo_light.svg).

I’m trying to turn on debugging with /debug=yes/, but I always get http 302 redirects to the usual login page, and nothing in the log.

did you try run ./daily.sh again? Still same issue in a private window?

Running daily.sh manually shows everything is nominal:

Updating to latest codebase                        OK
Updating Composer packages                         OK

Caching PeeringDB data                             OK

And the issues are the same in a private window.

Really does sound like you’re running a proxy here.

No, I am not. However, even if I were, the resolution for the other guy with a similar issue (which was to set up a cert on his web server) is already in place, so it’s definitely something else causing the problem.

Got the same problem after upgrading to gdf90881 from a month or so old version. I am NOT using a reverse proxy - just a regular Nginx web server with SSL, serving PHP content directly.

The login screen is broken, as the site tries to load objects via HTTP, not HTTPS.

I am using https URL in APP_URL in .env as well as in config[‘base_url’], even tried adding X-Forwarded-Proto “https” header via Nginx - no luck.

The only ‘fix’ I found is to modify app/Providers/AppServiceProvider.php and add:

    $this->app['url']->forceScheme('https');

I had to do the same thing to get the HTTPS URLs working correctly. What’s the real fix? :-\

I also had to add the line, which I believe should be added to the public function boot() { … }.

The ultimate “fix” will have to come from the developers patching LibreNMS to add this line when your base_url begins with https. Until then, I’ve disabled daily updates within the config.
