Published: 12 Jul 2018 Last Modified Date: 16 Mar 2020
After configuring Tableau Server to use Azure Active Directory (AD) single-sign on, the following error occurs:
"Unable to Sign In Invalid username or password"
Active Directory authentication
SAML SSO with Azure Active Directory as IdP
Work with your database administrator to ensure that Azure Active Directory is passing the sAMAccountName in its "username" attribute inside the SAML assertion by choosing the user.onpremisessamaccountname attribute in Azure Active Directory.
Tableau Server requires the sAMAcoountName attribute to authenticate users in on-premises Active Directory.
