Hi,
We are working on Power BI migration from INFY to TATA.
I have a user TATA.nato@tata.com.
a. with this user Iam able to connect to Azure databricks using Power BI desktop in INFY tenant.
b. Iam logged in as TATA.nato@tata.com and switched to tenant INFY in Power BI.
But when i come to Power BI service, its giving error when login with Oauth2.
Failed to update data source credentials: [Microsoft][ThriftExtension] (14) Unexpected response from server during a HTTP connection: Unauthorized/Forbidden error response returned, but no token expired message received.Hide details
Status code: 400
Any help would be appreciated.
Note:
Earlier i was able to connect with email id TATA.nato@TATA.onmicrosoft.com
Weeked they change the userid TATA.nato@TATA.com

@naveens here are few things that you can try.
1. Re-authenticate in Power BI Service
- Go to Power BI Service → Settings → Data Sources.
- Locate the Databricks data source.
- Click Edit Credentials.
- Choose OAuth2 and re-authenticate using the correct Azure AD account (TATA.nato@tata.com) under the INFY tenant.
2. Clear Cached Credentials
3. Verify Azure AD Permissions
- Ensure TATA.nato@tata.com has access to the Databricks workspace in the INFY tenant.
- Check if the user is assigned to the correct Azure AD group or Databricks workspace role.
