Sharepoint (Onedrive) single tenant with a shared secret

What is the problem you are having with rclone?

I registered a single tenant application in the Azure portal.

Now I am able to fetch the access key without entering my personal credential and by using client_id with this command. This is called as Access token request with a shared secret by Microsaft.

curl --location --request GET '<..>/oauth2/v2.0/token' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'client_id=3e72e39d-a253-48b5-<..>' \
--data-urlencode 'client_secret=u0t8Q~sIGNmE~<..>' \
--data-urlencode 'grant_type=client_credentials' \
--data-urlencode 'scope='

But if I want to retrieve the access token using rclone I have to enter the my personal credential. I followed this instructions and used this command.

rclone --onedrive-drive-type "business" --onedrive-token-url '<..>/oauth2/v2.0/token' -vvv --onedrive-auth-url
"<..>/oauth2/v2.0/authorize" authorize onedrive -- "3e72e39d-a253-<..>" "u0t8Q~sIGN<..>"

May I miss a detail, at the moment I do not understand, why I need to enter my personal credentials? Instead it should be enough to use client_id and

Run the command 'rclone version' and share the full output of the command.

rclone version ✘ INT 4m 9s 08:24:16
rclone v1.53.3-DEV

  • os/arch: linux/amd64
  • go version: go1.18

Which cloud storage system are you using? (eg Google Drive)


The command you were trying to run (eg rclone copy /tmp remote:tmp)

 ./rclone --onedrive-drive-type "business" --onedrive-token-url '<..>/oauth2/v2.0/token' -vvv --onedrive-auth-url "<..>/oauth2/v2.0/authorize" authorize onedrive -- "3e72e39d-a253-48b5-<..>" "u0t8Q~sIGNmE~<..>"

The rclone config contents with secrets removed.

There is no rclone config as this is used to get the access token only.

Because the general user base is not going to compile a complex curl command to get an ID and they are going to use a standard API method provided by MS to get it.

My understanding is that client_id is for identifying the app in use (in this case rclone).

OAuth always requires a user as well - at least the way rclone uses it with grant_type authorization_code.

This could probably be made to work by using a grant_type of client_credentials but it would require a bit of work in rclone.

BTW You'll need to put the client_id and client_secret in the config file too as rclone will need them to re-validate the token when it expires I think.

If you can get a token with your curl command, you can try putting that in the rclone config file - does that work?

This was also new to me, but it seems to be correct. In the RFC it is described as followed:

either authorization server credentials (handle-based design; see Section 3.1) or authorization server shared secret/public key

And yes, it is mandatory to store the client_id andclient_secret and auth_url and token_url as these URLs have to contain the tenantId as described by Microsoft.

I put the created access_token into the config and yes it is working.

Thanks for your comment, but please be aware that the curl request is using the normal OAuth API from Microsoft titled "First case: Access token request with a shared secret".

They are also using a hacky curl request to demonstrate how to use it.

I got that. Good luck!

If we want to make this work in rclone it is going to need a patch I think.

Do you want to have a go at it?

The relevant bit of rclone is here: rclone/oauthutil.go at master · rclone/rclone · GitHub

It in turn calls this library oauth2 package - - Go Packages and I think what is needed is use this package instead clientcredentials package - - Go Packages for 2-legged oauth flow...

Yes, I will try to implement this. My Next steps are

  1. set up dev env
  2. hack
  3. create PR

Great :slight_smile: Let me know if you need help!

Here is how to do a source install
