 # Authentication issues in Azure HDInsight
 
 This article describes troubleshooting steps and possible resolutions for issues when interacting with Azure HDInsight clusters.
 
-On secure clusters backed by Azure Data Lake (Gen1 or Gen2), when domain users sign in to the cluster services through HDI Gateway (like signing in to the Apache Ambari portal), HDI Gateway will try to obtain an OAuth token from Azure Active Directory (Azure AD) first, and then get a Kerberos ticket from Azure AD DS. Authentication can fail in either of these stages. This article is aimed at debugging some of those issues.

 ### Cause
 
-To get to this stage, your OAuth authentication is not an issue, but Kerberos authentication is. If this cluster is backed by ADLS, OAuth sign in has succeeded before Kerberos auth is attempted. On WASB clusters, OAuth sign in is not attempted. There could be many reasons for Kerberos failure - like password hashes are out of sync, user account locked out in Azure AD DS, and so on. Password hashes sync only when the user changes password. When you create the Azure AD DS instance, it will start syncing passwords that are changed after the creation. It won't retroactively sync passwords that were set before its inception.

 If you think passwords may not be in sync, try changing the password and wait for a few minutes to sync.
