Power BI ADAL Authentication Issues – Having trouble with ADAL authentication in Power BI. Anyone dealt with this before?

I am facing authentication issues in Power BI when using ADAL (Azure Active Directory Authentication Library). Despite following the standard authentication flow, I keep encountering errors that prevent access. Has anyone experienced similar issues, and if so, what solutions or workarounds did you find?

Answer 1

Yes, ADAL authentication issues in Power BI are common, especially with expired tokens, incorrect permissions, or deprecated ADAL libraries. First, ensure you're using MSAL (Microsoft Authentication Library) instead, as ADAL is deprecated. Also, check that the Azure AD app has the correct API permissions (e.g., Power BI Service, Read/Write). If you're using service principal authentication, confirm that the tenant ID, client ID, and secret are correct. Clearing cached credentials and re-authenticating might also help. If errors persist, share the exact error message for a more targeted solution.
