I am working on file uploader to One Drive for Business account.
My application should have the least privileged access as possible duo security reasons.
I can authenticate and generate correct tokens, but I cannot create App Folder when I have only that access: Files.ReadWrite.AppFolder. I got below response:
{"error":{"code":"accessDenied","message":"The caller does not have permission to perform the action."}}
When I extended my privileges to Files.ReadWrite.All the same request succeeded.
Request: GET https://{tenant}-my.sharepoint.com/_api/v2.0/me/drive/special/approot/
I known correctly tenant, I just haven't provided it in that post.
Does One Drive for Business work with App Folder privileges? I am not sure according to below document:
https://learn.microsoft.com/en-us/onedrive/developer/rest-api/api/drive_get_specialfolder
Unfortunately the Files.ReadWrite.AppFolder does not work for OneDrive Business (see this documentation). It's something we definitely want to fix.

TLDR -
I want users of my employer's organization who install my CLI tool to be able to use it to run commands that use the GitHub rest api that require permissions the user doesn't personally have, while restricting the user from using the CLI tool to perform unintended actions with the elevated permissions needed by the CLI tool. Is there a way to create a CLI tool that 1. uses permissions the users of the CLI tool don't have while at the same time 2. prevents those users from using the CLI tool's elevated permissions to perform unintended actions?
Extended -
I'm building a CLI tool for my employer's organization so that the organization members can automatically create a new branch and simultaneously add branch protection and create a PR. As far as I know, updating branch protection with the GitHub API requires admin access. However, not all of the users who use this CLI tool will personally have those permissions for their user account. But a user in the organization should still be able to use the CLI tool (which uses permissions the user potentially doesn't have).
I thought about using a personal access token so that the users aren't using a single set of centralized credentials (github app creds), but then the CLI tool would have access to at least one of the user's personal repositories and potentially wouldn't have the required permissions required by the CLI tool.
So is there a way to build a tool as a package that can be installed on a users machine that...
has permissions that the user of the tool potentially doesn't have and
prevents the user from doing anything unintended. e.g. the tool (which has admin permissions) can add branch protection rules, but the user shouldn't be able to use the tool's elevated permissions for anything else - e.g. getting the interaction limits for an organization
prevents the user from using the tool in any organization repo they don't have access to.
Ok, that's the gist of it, but I will go into more detail in case that helps.
So currently I'm using a GitHub app and giving it the required permissions (e.g. admin read/write for branch protection rules). I'm using octokit to authenticate to the GitHub API with the GitHub App. To do this, I'm passing in the app id, private key, and the installation id.
package structure
- .env
- authenticate_and_do_stuff.ts
authenticate_and_do_stuff.ts
// authenticate with GitHub app creds
// see https://github.com/octokit/octokit.js#authentication
const octokit = new Octokit({
authStrategy: createAppAuth,
auth: {
appId: process.env.GITHUB_APP_APP_ID,
privateKey: process.env.GITHUB_APP_PRIVATE_KEY,
installationId: process.env.GITHUB_APP_INSTALLATION_ID,
},
});
// create branch, add branch protection, etc.
octokit.rest.do stuff ...
This isn't ideal because then the user who installs the package needs those environment variables to be authenticated. And once they have those creds, they would be able to use them to do other things they potentially don't have permissions for (e.g. with the admin read/write permission the GitHub app has permissions for). So my thought is to have the user provide the authentication credentials that aren't the Github app credentials. This way, each user is using different credentials they provide. As for the reasons stated above, personal access tokens cannot be used. So the ideal situation is as follows -
A user installs the package - npm i my-github-cli-tool.
- node_modules
|
--- my-github-cli-tool
|
--- authenticate_and_do_stuff.ts
|
- some_custom_app_file.ts
- .env.cli_tool
They generate credentials and put them into a custom env file e.g. .env.cli_tool.
They use the CLI tool to create a new branch in an organization repo they have access to, create the branch protection rules (with the admin read/write access that the user doesn't have, but the credentials in step 2 has).
If the user tries to alter the cli tool or use the credentials in step 2 to use it to access repos they don't have access to or perform other actions with the admin read/write permissions, they shouldn't be able to.
If I stick with using the GitHub app, the source code on the user's machine has to get the credentials somehow. And those credentials need to have elevated permissions that the user might not have. So if these credentials are exposed to the source code on the user's machine, doesn't that mean the user can just grab those credentials and use them for nefarious purposes?
I have written thousands of lines of Apps Scripts in an internal enterprise setting, but have been wracking my brain on this without any success for some time. Here's the use case:
App Script #1 is run by users in our organization with Calendar read/write permissions. In order to operate correctly, however, it requires access to certain data that can only be accessed by a separate user with different permissions.
App Script #2 is run as this second user, and serves up an API endpoint via doPost() or doGet() that returns the requested information.
For security reasons it is not possible to grant user #1 the full permissions required for user #2, hence the desire for user #2 to expose an API that provides only a very specific set of information to user #1.
The most intuitive solution would appear to be for user #2 to deploy an Apps Script with the "execute the app as" field set to "me", and the "Who has access to the app" field set to the organization's GSuite domain (for security reasons this must be restricted to within the organization).
However if user #1 then tries to hit that endpoint using UrlFetchApp, the request will fail (I believe with an HTTP 403) since the request does include a session token to prove that the request originates from within the same GSuite organization. Google does not seem to provide a way to generate such a session token; attempting to set an "Authorization" header with the value "Bearer " + ScriptApp.getOAuthToken() does not work.
I have also tried using the Apps Script API to have user #1 execute the script which was deployed by user #2, however the Apps Script API makes it clear that scripts can only be executed in the context of the calling user.
I've also read separately that Google Apps Scripts do not play well with service accounts (https://issuetracker.google.com/issues/36763096).
Hopefully I'm missing something obvious. Any ideas?
GOAL: Create users in Azure Active Directory using our Global Admin account from an API.
PROBLEM: Every single way I try, I get "unauthorized".
WHAT I'VE TRIED:
I've been focusing mostly on this: https://graph.microsoft.com/v1.0/invitations
I've tried as outlined here
the "Authorization Bearer {token}" is problematic -- I can't seem to properly retrieve tokens, using any of the built URLs recommended (ie, combining ClientID & TenantID in the URL.)
I've tried the relevant portions of this, including creating the app, setting permissions on the app, trying both Web API and Native. I'm able to get a code back, but using it always comes back with Unauthorized.
As an aside, I am using Nintex to run this web service, as it is part of my workflow. Typically, web services don't give me issues. So, this sucks.
I'm missing something, here. Any thoughts or direction?
UPDATE: Removed the word "method" - bad choice of phrasing.
If you want to use Microsoft Graph explorer to create user as the global admin, you could use POST https://graph.microsoft.com/v1.0/users, and the required permission is:
Permissions
For the details, you could read Create user.
Global admin runs as a user by default. To grant access to Active Directory, you need to elevate permissions in the portal.
I'm not convinced you have the permissions to create the user, and that's why I think you're getting the error.
Also, try and avoid using Global Admin. Create a Service Principal and provide more granular permissions.
My question seems similar to OneDrive for Business REST API - PUT,POST - 401 Unauthorized
However, instead of uploading, I am trying to download a file. What's strange is that I do get the file contents and data, but the response code is a 401.
Any idea why? Of course, I would like to be receiving a 200 and not have to ignore the response code.
As far as my Azure AD app permissions go, I am allowing pretty much all read permissions under delegated permissions for Office 365. I have listed all the permissions I selected here, for your reference.
Delegated Permissions I am allowing for Office 365:
Read managed metadata
Run search queries as a user
Read items in all site collections
Read user files
Delegated Permissions I am allowing for Windows Azure Active Directory:
Enable sign-on and read users' profiles
I have not enabled anything under Application Permissions.
There is a bug in our implementation - if you provide an Authorization: header with a bearer token on the download URL (which is pre-authenticate) the service rejects the authentication (hence the 401) but since the URL is pre-authenticated, the contents of the file are still sent.
We're working on a fix. You can track the status by watching this issue on our GitHub repo: https://github.com/OneDrive/onedrive-api-docs/issues/189
I want to get started with the Office365 Unified API , so I decided to register a new web app to our azure directory.
In the section: "permissions to other applications" , I select Office365 unified API(preview)
I only get set delegated permission (I don't have all admin powers in our tenant), so I choose the ones I need (user profiles, sign-in , the exact number does not matter).
When I save the configuration I get the message
Could not update the configuration for app ""
Information tells me:
Unauthorized. You do not have sufficient permissions to access this resource.
The strange is , that when I log out and return to the application in the Azure Portal, I do see those modification in the configuration ?!
Finally when I try to call the REST endpoint (with valid Accesstoken etc..) I get this message:
{"error":"invalid_grant","error_description":"AADSTS65001: No permission to access user information is configured for 'f1299649-ea20-4cf6-9cd6-afb69d9b5760' application, or it is expired or revoked.\r\nTrace ID: 69ab1a6c-eeda-4351-8e1e-2b774c19a5a0\r\nCorrelation ID: 968a962e-d851-48bb-ad6f-3f05ea7b8efe\r\nTimestamp: 2015-06-18 20:12:15Z","error_codes":[65001],"timestamp":"2015-06-18 20:12:15Z","trace_id":"69ab1a6c-eeda-4351-8e1e-2b774c19a5a0","correlation_id":"968a962e-d851-48bb-ad6f-3f05ea7b8efe","submit_url":null,"context":null}
So maybe the Azure Portal UI is right the first time and those permissions where never stored with the app ?
the application details in https://portal.office.com/myapps tell me this:
Permissions
This app works with data in your documents. It will be able to:
Read directory data
Sign you in and read your profile
Read all users'basic profiles
Access the directory as you
Read directory data
Sign-in as you and read your profile
What would be the next step to take to get this to work ?
What is your app trying to do (in terms of access to users, groups etc)?
Access the directory as you is a permission that requires admin consent. The portal unfortunately has a bug that it appears as though you have the permission, but that's not true. That's because there are 2 elements here - configuring the permissions your app needs which drives the consent experience AND the consent grant. The portal (under the covers) tries to consent the app for the permissions it requires within the developer tenant. A non-admin in this case has permissions to update the app configuration, but not to consent for those permissions in their tenant.
Hope this helps,
It is impossible to set permissions to Office 365 Unified API for your application even if you are tenant administrator due to error. I have tried it. Remember that whole Unified API is in Preview mode so there will definitely be other errors.
