[byewokko]

Add support for Microsoft Entra ID as a credentials provider.

Untested ChatGPT snippet:

from msal import ConfidentialClientApplication
import requests

# Configuration
TENANT_ID = "your-tenant-id"
CLIENT_ID = "your-client-id"
CLIENT_SECRET = "your-client-secret"
AUTHORITY = f"https://login.microsoftonline.com/{TENANT_ID}"
SCOPE = ["https://graph.microsoft.com/.default"]
GRAPH_API_ENDPOINT = "https://graph.microsoft.com/v1.0/users"

# Create an MSAL confidential client
app = ConfidentialClientApplication(
    client_id=CLIENT_ID,
    authority=AUTHORITY,
    client_credential=CLIENT_SECRET,
)

# Get token
result = app.acquire_token_for_client(scopes=SCOPE)

if "access_token" in result:
    headers = {"Authorization": f"Bearer {result['access_token']}"}
    users = []
    endpoint = GRAPH_API_ENDPOINT

    while endpoint:
        response = requests.get(endpoint, headers=headers)
        data = response.json()
        users.extend(data.get("value", []))
        endpoint = data.get("@odata.nextLink")  # pagination

    # Print user display names
    for user in users:
        print(f"{user['displayName']} - {user['userPrincipalName']}")
else:
    print("Failed to obtain token.")
    print(result.get("error"))
    print(result.get("error_description"))
