Password sync: Troubleshoot Azure Active Directory Pass-through Authentication

In order to enable the Azure AD Connect Pass-through Authentication feature, the Authentication Agent needs to be installed. Below are some of the errors that may arise while installing the Authentication Agent and enabling the Pass-through Authentication feature:

Authentication Agent installation issues

  1. Authentication Agent installation issues
    Collect agent logs from the server and contact Microsoft Support about the issue.

Authentication Agent registration issues

  1. Failure of Authentication Agent registration due to blocked ports
    Ensure that the server on which the Authentication Agent has been installed can communicate with Microsoft service URLs and ports listed here.
  2. Failure of Authentication Agent Registration due to token or account authorization errors.
    Make sure that a cloud-only Global Administrator account is used to enable the feature.
  3. An unexpected error occurred
    Collect agent logs from the server and contact Microsoft Support with your issue.

Authentication Agent uninstallation issues

  1. The below warning message appears when uninstalling Azure AD Connect:

    "Users will not be able to sign-in to Azure AD unless you have other Pass-through Authentication agents installed on other servers."

    This message appears if you have enabled Pass-through Authentication on your tenant and attempt to uninstall Azure AD Connect. Before uninstalling, please ensure that you have implemented high availability to avoid breaking user sign-in.

Issues with enabling the feature

  • Unable to enable the feature because there were no Authentication Agents available

    At least one active Authentication Agent is necessary to enable Pass-through Authentication on your tenant. The Authentication agent can be installed by installing Azure AD Connect or you can install a standalone Authentication Agent.

  • Unable to enable the feature due to blocked ports

    Ensure that the server on which Azure AD Connect is installed can communicate with Microsoft's service URLs and ports listed here.

  • Unable to enable the feature because of token or account authorization errors

    Make sure that a cloud-only Global Administrator account is used to enable the feature.
