KeyError: 'FedAuth' when aquireing user token

[chamorin]

I want to fetch a file from a SharePoint website. So first, I tried to run the exemple code found in the doc replacing username, password and the site with my company's website like here:

import os
from getpass import getpass
from office365.runtime.auth.user_credential import UserCredential
from office365.sharepoint.client_context import ClientContext

password = getpass("Password: ")
site_url = "https://company.sharepoint.com"

ctx = ClientContext(site_url).with_credentials(UserCredential(os.getenv('USERNAME'), password))
web = ctx.web
ctx.load(web)
ctx.execute_query()
print("Web title: {0}".format(web.properties['Title']))

When I run it, I enter my password, press enter and it prints this: Cannot get binary security token for from https://login.microsoftonline.com/extSTS.srf

Here's the full error message:

Thanks in advance

Greetings,

according to trace log, it seems it fails on acquiring a security token, revealing some additional details might help to pin-point the root cause:

• is federated account is involved to connect to SharePoint?
• whether MFA is enabled

Could you give it a try with App-only flow instead of user credentials flow?

Here is a step-by-step instruction on how to configure app principal and grant access.

Hello,

I had the same problem, KeyError: 'FedAuth'.

Try using AuthenticationContext instead of UserCredential

from office365.runtime.auth.authentication_context import AuthenticationContext from office365.sharepoint.client_context import ClientContext

site_url = "https://company.sharepoint.com" ctx_auth = AuthenticationContext(url=site_url) ctx_auth.acquire_token_for_user(username=user, password=password)

ctx = ClientContext(site_url, ctx_auth)

I had the same problem and resolved it using app principal as described in this issue: #191

[ClearSafety]

The problem is with authentication. In my case, I couldn't use my credentials (user and password) because of the way my company setup the access to the Sharepoint.

The solution can be found in the section "Setting up an app-only principal with tenant permissions" of https://learn.microsoft.com/en-us/sharepoint/dev/solution-guidance/security-apponly-azureacs

Once you have access to client_id and client_secret, use them to create the authentication. Please, see the example below:

from office365.sharepoint.client_context import ClientContext from office365.runtime.auth.authentication_context import AuthenticationContext

client_id="{client id}" client_secret="{client secret}" url = "https://{tenant}.sharepoint.com/sites/{site}"

ctx_auth = AuthenticationContext(url) if ctx_auth.acquire_token_for_app(client_id, client_secret): ctx = ClientContext(url, ctx_auth) web = ctx.web ctx.load(web) ctx.execute_query() print("Web title: {0}".format(web.properties['Title']))

else: print(ctx_auth.get_last_error())
