Status?

[marfier]

Hi,

Is this project still being maintained? Any possibility for a bit of documentation and context?

Thanks.

[jpvanoosten]

Thanks for your interest.

I'm currently working on the README.md in the dev branch. See 566a0ab.

There are a few more things on the road-map such as adding external users (currently the user manager admin interface is not yet finished), kicking users from the user manager interface, adding admins, Office 365 logins, and other features that are not quite ready for prime-time.

[jpvanoosten]

I've created a project for this repo to give an indication of what is on the road-map.

[marfier]

The dev branch is like an entirely different project!

[marfier]

@jpvanoosten is there a chance that this could be closer to complete before the beginning of school season (September 1)?

[jpvanoosten]

@GalacticLion7 I won't be working on this project much before September. This project is currently being used in a production scenario so it is "complete" for our needs. If you'd like to see a live demo (you won't be able to log in however) check it out here: https://discord.igad.nl

[marfier]

@jpvanoosten I would like to make a Discord server that is only limited to users within a school, in the form of a G-Suite organization. Is this the right project for that? I just tried it out using the G-Suite method, and it seems that anybody who has a Google account could authenticate in the portal.

I would also like to personalize the portal, but I can't find all the site assets.

[jpvanoosten]

@GalacticLion7 If you want to limit it to students in your organization, make sure you check the box "Internal" under "Application type" in your in the OAuth consent screen:

[jpvanoosten]

I would also like to personalize the portal, but I can't find all the site assets.

@GalacticLion7 The assets are in the /public folder and the PUG views (which generates the HTML) is in the /views folder. All images are in the /public/images folder. There you will find both the Adobe Illustrator (.ai) and PNG (.png) files that are used on the site. For example, just replace the public/images/brand_logo.svg file to use your own brand logo. If you want to change the file path to the brand logo, see: https://github.com/jpvanoosten/discord-user-manager/blob/968de0602a50d19bf4574cda80b4b7ee44bb1c13/views/nav.pug#L12

[marfier]

Thank you for clearing it up.

How about limiting invites to specific groups from G-Suite?

[jpvanoosten]

How about limiting invites to specific groups from G-Suite?

I don't think there is an automatic way to do this. I think you'd have to add the "https://www.googleapis.com/auth/admin.directory.group.readonly" scope to the GoogleStrategy in /routes/google.js (You'll also have to update your Google app project to allow this scope in the OAuth consent screen in the Developer Console). See: https://github.com/jpvanoosten/discord-user-manager/blob/566a0ab5e2baec9130ed3b984ee3d357607cebb6/routes/google.js#L66

Then, in the "verify" callback of the GoogleStrategy, you'd have to check the groups that the user is in. If the user isn't in the right group, then throw an error in the strategy.

See: https://developers.google.com/admin-sdk/directory/v1/quickstart/nodejs and https://developers.google.com/admin-sdk/directory/v1/guides/manage-groups#get_all_member_groups

I'm not 100% sure if this is correct advise, but I hope it gets you looking in the correct direction.

[marfier]

Aside from that, I'm getting a bunch of errors from the log: https://pastebin.com/1KwchWwh

Also, when I authenticated with my Google account, it displayed an error ("An error occured when adding you to the Discord server. Please contact the owner of the Discord server for more information"). I was able to finish Step 3 and it showed that my (alt) Discord account was linked, but I don't see the server on my Discord server list.

@GalacticLion7 The test scripts tries to add and remove the TEST_USER_DISCORD_ID user. Are you running the tests?

[marfier]

Nope, I left alone those env variables. I'm running it on production. On 7 Sep 2020, 03:05 +0400, Jeremiah van Oosten notifications@github.com, wrote:

[jpvanoosten]

@GalacticLion7 The Sequelize debug output is clogging up the log output. Can you set the DEBUG environment variable to this:

DEBUG=discord-user-manager:*,-discord-user-manager:sequelize

and run the script again?

Jest did not exit one second after the test run has completed.

This usually means that there are asynchronous operations that weren't stopped in your tests. Consider running Jest with `--detectOpenHandles` to troubleshoot this issue.

How about limiting invites to specific groups from G-Suite?

I don't think there is an automatic way to do this. I think you'd have to add the "https://www.googleapis.com/auth/admin.directory.group.readonly" scope to the GoogleStrategy in /routes/google.js (You'll also have to update your Google app project to allow this scope in the OAuth consent screen in the Developer Console). See:

https://github.com/jpvanoosten/discord-user-manager/blob/566a0ab5e2baec9130ed3b984ee3d357607cebb6/routes/google.js#L66

Then, in the "verify" callback of the GoogleStrategy, you'd have to check the groups that the user is in. If the user isn't in the right group, then throw an error in the strategy.

See: https://developers.google.com/admin-sdk/directory/v1/quickstart/nodejs and https://developers.google.com/admin-sdk/directory/v1/guides/manage-groups#get_all_member_groups

I'm not 100% sure if this is correct advise, but I hope it gets you looking in the correct direction.

Unfortunately, I'm not very much of a JS developer, but I did find this package: https://www.npmjs.com/package/google-group-manager.

[jpvanoosten]

So I started a new feature branch feature_restrict_google_group for this, but I didn't get very far yet.

@GalacticLion7 Maybe you want to take a look at the routes/google.js file to see if you can make any progress?

As far as I can see, it is likely that a service account will be required to query the groups on the domain.

[jpvanoosten]

Okay.. I think I have a basic idea about how to restrict user accounts by their group membership. I've added a test script that will list (at most 200) the email address of the groups that a particular user is a member of. See testGSuite.js. Change the hard-coded userKey field in that file to show group membership for another user.

There are a few things that you'll need to do to get this to work:

1. Add the https://www.googleapis.com/auth/admin.directory.group.readonly scope to your web app in the Google Developer Console
2. Get an OAuth access token for an admin account on your Google Apps domain (see the getToken function
3. Add a function to check the groups for the user that wants to authenticate with the Discord User Manager and compare the group memberships with the allowed groups (not done).

This is still a work in progress and a massive struggle to get this to even remotely work as my first several attempts all failed miserably. Finding the right sample to solve it for this particular use case is like finding a needle in a haystack (or I was just focused on doing it in a particular way, which apparently wasn't supported....)

Please let me know if you're still interested in this functionality. If you are, I'll continue to try to make it work nicely for you (with a utility script to create the token file and add the functionality to the google login route).

[jpvanoosten]

Okay, checkout dced0c2f03fbc4adf4747b4c1cf20c30af89cd8b in the feature_restrict_google_group branch for an updated. I've added a utility script that can be used to get the OAuth2.0 token for your admin account. Use

npm run oauth:google

or

yarn oauth:google

to create the token.json file that is needed to query the user's groups. I've also added a function to list the user's groups (but currently doesn't do anything with them).

[jpvanoosten]

@GalacticLion7 Let me know if you need help with this...

[marfier]

@jpvanoosten the script seems to hang after being executed. I've let it run for ten minutes. Are there any logs we can see?

[marfier]

Also, in the latest feature_restrict_google_group, there's an error when I try to start the application.

@GalacticLion7 I do need to spend some time on error handling. I've added a "Sign in with Microsoft" button and the routes/azure.js route to handle logging in with Azure AD. Perhaps this is due to the Azure AD client not being configured? I should look into wrapping those routes in checks if the CLIENT_ID is not configured for those services, not to include them ... So much to do, so little time...

Anyways, you marked your comments as resolved so maybe you figured it out already?

If you get the Google logins working, and you add a token file for your Google Admin user (using the utils/getGoogleOAuthToken.js script), then you should see a list of groups for the logged in user. The code to filter the user by the group membership still isn't there yet.

Another issues is when the access token expires, currently you'll need to generate a new one. I need to investigate how to refresh the access token if it's expired.

[marfier]

Anyways, you marked your comments as resolved so maybe you figured it out already?

It's because I overlooked your 4th last comment before I commented about my issues.

Get an OAuth access token for an admin account on your Google Apps domain

This sentence caught me, because I don't actually have access to an admin account. However, I am a user of the relevant groups (the ones I'm looking to whitelist), and I just want to confirm that I have read access to the users inside them by sending an API request (see HTTPie snippet below) to obtain the the list of users in a particular group I'm in.

I just need help to figure out where I can obtain an "access token" (that part of the Admin SDK documentation is too difficult to wrap my head around).

If it turns out that I don't have read access to the groups, then unless there's a workaround, I would need to convince the system administrator to specially give my G-Suite account the relevant permissions. That may be difficult, since SA's are usually not developers, so the idea won't quite easily get to them.

[jpvanoosten]

I am a user of the relevant groups

This is not enough to query the groups of other users that try to login to your system. It's not even enough to read a list of your own groups!

The best solution is to request your Google Apps administrator to create a new admin role (called "Group Read" for example) that has only the Group > Read privilege under the "Admin API privileges" section (as shown in the screenshot below) and add you to that role.

You can test if this privilege is working by going to: https://developers.google.com/admin-sdk/directory/v1/reference/groups/list and scroll to the bottom of that page (replace the userKey value test@example.com with your own G Suite email address) and make sure only the https://www.googleapis.com/auth/admin.directory.group.readonly scope is checked (as shown in the screenshot below) and execute the query. You should be presented with an OAuth consent screen. Login using your own G Suite account and if you are able to see a list of groups for the specified in the userKey field, then the privilege is working.

I've setup a Discord server to continue this conversation: Join the Discord User Manager Discord Server I use this server for testing. The "logs" channel is used for testing log messages. Feel free to mute that channel!
