Setting up authentication on a jitsi server

savannidgerinel · February 7, 2022, 6:35am

This was last covered several years ago in Jitsi-meet: how to enable authentication?, however the solution there is incomplete and no longer seems to work.

Can anyone help me figure out how to set up authentication on a jitsi server with Nixpkgs 21.11? I want to require authenticated users to create a channel, but anonymous users are allowed to join it.

I’ve gotten to a state where I can get my jitsi server to prompt me for a password, but it never recognizes my as a host. Further, I can find no errors in the prosody, videobridge, or jicofo log files. My configuration currently looks like this (jitsi_fqdn = jitsi.luminescent-dreams.com)

    services.jitsi-meet = {
      enable = true;
      hostName = jitsi_fqdn;
      config = {
        authdomain = jitsi_fqdn;
        enableInsecureRoomNameWarning = true;
        fileRecordingsEnabled = false;
        liveStreamingEnabled = false;
        prejoinPageEnabled = true;
        hosts = {
          domain = jitsi_fqdn;
          anonymousDomain = "guests.${jitsi_fqdn}";
        };
      };
    };

    services.jitsi-videobridge = {
      enable = true;
      openFirewall = true;
    };

    services.coturn = {
      enable = true;
      ...
    };

    services.prosody = {
      allowRegistration = true;
      virtualHosts = {
        "${jitsi_fqdn}" = {
          enabled = true;
          domain = "${jitsi_fqdn}";
          extraConfig = ''
            authentication = "internal_hashed"
            '';
        };

        "guests.${jitsi_fqdn}" = {
          domain = "guests.${jitsi_fqdn}";
          enabled = true;
          extraConfig = ''
            authentication = "anonymous"
            c2s_require_encryption = false
            '';
        };
      };
    };

    services.jicofo = {
      enable = true;
      config = {
        "org.jitsi.jicofo.auth.URL" = "XMPP:${jitsi_fqdn}";
      };
    };

This is the closest I’m getting to an error message at this point:

But this is only a fragment of the printouts that appear to occur on every auth attempt. I see at least a hundred such lines, again with no obvious error.

I suspect that package development for Jitsi-Meet hasn’t matured. It’ll allow a quick basic setup of Jitsi-Meet, but the service options to modify the sub-services (e.g. posody, jicofo) seems to be missing.

Per the Jitsi docs [1] for a non-NixOS setup of authentication for Jitsi where only authorized users can create rooms and guests can join, as you specified.

[1]: Secure Domain setup | Jitsi Meet

The four major steps mentioned there:

Configure prosody for guests and auth users.
Add guest domain to Jitsi frontend (not nginx).
Configure jicofo to only accept conference allocation requests from authenticated domain.
Create users in prosody.

So here’s what I would troubleshoot…

1 Configure prosody for guests and auth users

For non-NixOS, this is needed in /etc/prosody/conf.d/$(hostname -f).cfg.lua…

VirtualHost "jitsi.luminescent-dreams.com"
  authentication = "internal_hashed"

VirtualHost "guests.luminescent-dreams.com"
  authentication = "anonymous"
  c2s_require_encryption = false

You seem to attempt this in your config for services.prosody. It seems you expect your manual prosody config to merge with the jitsi-meet automatic prosody config. I’m not certain that happens (it could, I just don’t know).

I recommend reviewing the prosody config file generated by NixOS and verify the meet.luminescent-dreams.com virtual host has authentication = "internal_hashed".

I found mine with cat /etc/systemd/system/prosody.service | grep "X-Restart-Triggers" | sed 's/X-Restart-Triggers=//' | xargs cat

2 Add guest domain to Jitsi frontend (not nginx)

var config = {
  // ...
  hosts: {
    domain: 'meet.luminescent-dreams.com',
    anonymousdomain: 'guests.meet.luminescent-dreams.com',
  },
}

Note the lowercase ‘d’ in anonymousdomain. You used anonymousDomain, but the jitsi-meet module doesn’t explicitly employ any mechanism to convert the Nix camelcase convention into that used by Jitsi.

3 Configure jicofo to only accept conference allocation requests from authenticated domain

Supposed to update /etc/jitsi/jicofo/sip-communicator.properties with…

org.jitsi.jicofo.auth.URL=XMPP:meet.luminescent-dreams.com

And possibly have this in /etc/jitsi/jicofo/jicofo.conf…

jicofo {
  authentication: {
    enabled: true
    type: XMPP
    login-url: meet.luminescent-dreams.com
 }
 ...

You accomplish the first per the NixOS options for services.jicofo.config.

I don’t know if the second is required. Maybe the jicofo module needs an update to support this? I’d save this this as a last resort.

4 Create users in prosody

Run something akin to prosodyctl register <username> meet.luminescent-dreams.com <password> for each user you want to add to your system. Looks like an admin has to choose passwords for users instead of letting users set a private password.

Conclusion

I’d start with anonymousdomain first, then verify the prosody config file, then register a user if you haven’t already.
Finally, restart services (prosody, jicofo, jitsi-videobridge2).

I’ve yet to find time to upgrade my jitsi server to use authentication, so this write-up is my exercise in learning the process now for when I have time to implement later.

Hope this helps.

Potentially, yes. I hadn’t noticed the capitalization issue. I think I’ve compared my work to what you posted here and everything was the same.

However I also think that there’s a formatting issue. When I look at the prosody config file, I see lines related to all of this that aren’t indented in the areas where they should be. I haven’t had time to manually fix the configuration file to test that theory, yet.

savannidgerinel · February 18, 2022, 1:52am

No luck.

Or some luck. Something like that.

I corrected the spelling error, went over everything very carefully, and now when I try to log in, it gets stuck with the message “obtaining session-id”. And then I get this error message in the console:

2022-02-18T01:48:11.582Z [features/authentication] <h/</<>:  authenticateAndUpgradeRole failed 
Object { authenticationError: "not-authorized", message: "not authorized user domain" }

authenticationError: "not-authorized"

message: "not authorized user domain"

But, at the same time, I am able to log in to the prosody server with that username and password. So something at least is working.

I think maybe my next step will be to fix the prosody module. I’ve figured out that the extraConfig stanzas that I put above, which are supposed to be associated with a virtualHost, are actually being put at the very end of the prosody config file. So, no telling how prosody is interpreting that.

I found a post [1] related to this particular authentication error on jitsi’s forum.

Unfortunately, the final solution there was to drop a “bare-metal” install on Ubuntu in favor of a Jitsi docker container. Still, if the docker container works, then it can provide a source of working configs to compare against.

From the “help” given in the thread, it seems like authentication is difficult to set up. And there may be outstanding bugs, according to this comment [2], that are fixed in the docker image released by Jitsi. And the fix appears to be using the jicofo.conf I mentioned previously…

And issue posted for nixpkgs [3] suggests auth won’t work without jicofo.conf as new keys added to jicofo.conf cannot be set in sip-communicator.properties. Possible workaround provided by betaboon.
