Open saltstack-admin opened 1 month ago

saltstack-admin commented 1 month ago

Is there an existing issue for this?

Describe the issue

Hello,

I installed on a new system Ubuntu 24.04 and followed the documentation here: https://github.com/ubuntu/authd/wiki/01---Get-started-with-authd

I checked with our MS Admins multiple times the configuration, but nonetheless I get always this error: could not get user info: could not fetch user info: could not get user groups: Insufficient privileges to complete the operation.

Where does the issue happens

Steps to reproduce it

1) Install Ubuntu 24.04 2) Follow the documentation: https://github.com/ubuntu/authd/wiki/01---Get-started-with-authd
3) Login through GDM or login, a QR code and an Auth code is displayed 4) Navigate to microsoft.com/devicelogin , enter the Auth code, log in with MS Entra ID user and press lastly on "register" 5) After press on register the website microsoft.com/devicelogin tells me a successful login 6) On GDM the window with the QR code closes itself and goes back to user selection screen, the command "login" shows the error: could not get user info: could not fetch user info: could not get user groups: Insufficient privileges to complete the operation.

Hey! Thanks for the detailed bug report. It seems that you can’t list groups from your application.

Seeing Insufficient privileges to complete the operation.: are you sure you followed those steps in particular? You need to ensure that you give the application the correct API permission (delegated through the admin, not the application ones).

saltstack-admin commented 1 month ago

Hello,

that is the problem, before I created the issue, we triple-checked our configuration. Our application registration has permissions for "Microsoft Graph" with "GroupMember.Read.All", "openid" and "User.Read" as type "Delegated". We fulfilled the "Admin consent required" too. In Manage->Authentication->Advanced Settings we changed the slider for "Allow public client flows" to yes.

I will try to request screenshots from our MS Admins.

didrocks commented 1 month ago

Yes, sounds good to me (and we can’t really check that client side apart from getting failure when listing groups, which is what we do). Please get some screenshots on those config, just in case.

saltstack-admin commented 1 month ago

Hi,

got screenshots from our MS Admins. Picture 1 shows the API permissions and picture 2 shows the authentication permissions. 2024-08-07-EntraID1 2024-08-07-EntraID2

didrocks commented 1 month ago

I see that your IS department also added the application type permission for GroupMemeber.ReadAll which shouldn’t be necessary.

I wonder if that would cause a clash for you. There are limited chances to be due to this, but maybe starting removing this would be a first good step.

Also, do you know of other admin restrictions on group listing that your organization could have set? All the rest of the configuration seems correct to me.

Also, when you are getting the authentication screen on your webbrowser, which are the permissions requests listed?

saltstack-admin commented 1 month ago

I forwarded your suggestion and your question to our MS Admins.

About your last question: I do not get any requested permissions? The documentation does not have screenshots for comparison.

I get always a login screen with 6 steps, translated:

  1. Please provide the authentication code displayed below the QR code
  2. Select the user you want to login with and I select my.user@my.domain
  3. Please provide the password for my.user@my.domain
  4. Please verify the 2FA
  5. Do you really want to register the system against this "application registration"? I click on "next"
  6. You have successfully registered against the "application registration"

After that the GDM lock screen flashes once and reverts back to the user selection.

You are right, contrary to other providers, MSEntraID doesn’t show the admin approved delegated permissions to the user. So, that doesn’t help us that much on the debugging front.

You are using the stable version of the snap, correct? Do you mind switching to edge, we changed slightly the logic there (at least, it may give us better logs from the broker)

Facing exact same issue

Well, the last tries and the logs I provided had been made with the edge version. Is there an even more experimental version, that you want me to install?

didrocks commented 1 month ago

We can’t reproduce the issue here. There is no additional debugging that could help after searching on the documentation. The seems I’m surprised about as you are using the edge channel is that I don’t find trace of that error string: https://github.com/ubuntu/authd-oidc-brokers/blob/main/internal/providers/msentraid/msentraid.go#L104, which would be the direct error in the additional check calls we added there.

From the MS Entra ID documentation related to that issue, it seems that it’s really linked to permissions issues. Did you get any feedback from your IT department to ensure that the app permission is deleted and only the delegated ones are available? They should look if anything could prevent the application to list groups that the current user is member of.

Can you reexport your logs? Sometimes, the issues are the same but the root cause different. Reporting either another bug that we duplicate or printing all requested logs here will help. Thank you so much!

I got an answer from our MS Admins and they so only one suspicious log message:

Seeing a similar issue. Will grab logs and upload

myname101us commented 1 month ago

I also have this issue. Oddly, it works for some users and not others. Syslog is showing that it IS case sensitive. I am only seeing minor inconsistencies between users within Graph. Can confirm that no Conditional Access policies are stopping login. AuthD showing in syslog that it can't retrieve user info or groups.

Hey guys,

Same issue here I guess, below are my logs from gnome shell from terminal still getting same issue could not get user info: could not fetch user info: could not get user groups: Insufficient privileges to complete the operation.

Quick update: We believe that this issue is fixed via https://github.com/ubuntu/authd-oidc-brokers/pull/135. The fixed version is currently only available on the edge channel of the authd-msentraid snap. It would help us if you could try it out and report if it fixes the issue for you. If you do so, please switch back to the stable channel afterwards (because we use the edge channel for development and testing and can't guarantee that it's always compatible with the latest released version of authd).

I was experiencing this same issue with the failure to read groups. and per the last comment, I updated to the edge-channel to test the new fix, which resulted in a new error stating that it cannot validate the user info (forgot to copy the exact error).

I went back into EntraID and adjusted the permissions on the App Registration as follows; EntraIDBroker

Which are CLEARLY excessive, BUT: Once I made these changes and Granted Consent, my next attempt at logging in resulted in the following;

| == Qr Code authentication (use 'r' to go back) ==
| 1 - Wait for the QR code scan result
| 2 - Request new login code
| Select action: 1
| Insert 'r' to cancel the request and go back
| Create a local password:
| Repeat the previously inserted password or insert 'r' to cancel the request a

| Create a local password:
End of keyboard-interactive prompts from server
Creating directory '/home/test@XXXXX.com'.
Welcome to Ubuntu 24.04.1 LTS (GNU/Linux 6.8.0-1014-azure x86_64)

Now that this is working, I went back and checked Logs for the EntraID broker and found this;

Sep 15 13:12:24 server-sftp01 authd-msentraid.authd-msentraid[12045]: time=2024-09-15T13:12:24.538Z level=INFO msg="Serving requests as com.ubuntu.authd.MSEntraID"

So, it looks like that one specific Permission was the missing one, not all those other ones I added.

Hope this helps other people.

@divgo: Please change the permissions to exactly those which are listed in https://github.com/ubuntu/authd/wiki/03---How%E2%80%90to-configure (i.e. User.Read, GroupMember.Read.All, and openid - remove any other permissions) and try again. If that fails with a different error than "could not access user's groups: Insufficient privileges to complete the operation", please open a new issue and fill out the issue template with the logs. Thanks!

I switched to the Edge-Channel, refreshed and restarted the snap. After clicking through all the windows I get still the error with the insufficient privileges.

The logs do show only two new lines: Sep 16 13:55:44 myhost.my.domain authd-msentraid.authd-msentraid[8004]: time=2024-09-16T13:55:44.327Z level=WARN msg="missing required scopes: GroupMember.Read.All, User.Read" Sep 16 13:35:44 myhost.my.domain authd-msentraid.authd-msentraid[8004]: time=2024-09-16T13:55:44.327Z level=ERROR msg="could not get user into: the Microsoft Entra ID app is missing the GroupMember.Read.All permission"

So the access token that the authd broker receives after authentication doesn't have the GroupMember.Read.All and User.Read permissions. Could you double check that the Microsoft Entra app that's configured in /var/snap/authd-msentraid/current/broker.conf has those permissions and the admin consent was granted?

I asked my colleagues, they said yes and provided me this screenshot: image

@saltstack-admin: Did you also double check that the app in that screenshot is the one that's configured via the client_id option in /var/snap/authd-msentraid/current/broker.conf?

Hi,

@saltstack-admin: Did you also double check that the app in that screenshot is the one that's configured via the client_id option in /var/snap/authd-msentraid/current/broker.conf?

Yes, we did.

Today I had a meeting with our Micorosoft admins and we tried the excessive solution from divgo .

We got now a new error and had been able to determine, that our security policy is blocking all logins from authd. One of our policy enforces, that only compliant and known devices are allowed to use the application registration. Well, no Linux device can fulfill these requirements and Microsoft denies the login.

Our Microsoft admins had the idea, to exclude the application registration from this policy, but this is impossible as long as "Allow public client workflows" is enabled. According to the documentation of authd this option must be enabled and a dead lock is created.

If no one has an idea, I will close this issue in a few days, if I don't forget it.

That's interesting! Is that a Conditional Access policy? We plan to work on support for Microsoft Entra device registration, so I expect that you will be able to use authd with this policy at some point.

saltstack-admin commented 2 days ago

Yes, our problem is created by a Conditonal Access policy.
