Summary: Configure Excel Services in SharePoint Server 2013 to use the unattended service account for authentication to external data.

Excel Services in SharePoint Server 2013 provides three methods of using Secure Store Service to refresh the external data source in a workbook:

Using the unattended service account involves configuring an Active Directory account and granting it access to your data, storing the credentials for this account in Secure Store, and configuring Excel Services to use the stored credentials when it needs to refresh the data in a workbook.

The following steps are required to configure the unattended service account in Excel Services.

  1. Configure a data access account

  2. Configure Excel Services Global Settings

  3. Configure a workbook to use the unattended service account

The unattended service account requires an Active Directory account for data access. Have your domain administrator create an Active Directory account that you can use for data access.

After the account has been created, you must grant this account read access to the data source that you will be using in your data-connected Excel workbook. Use the following procedure to create a logon for the data access account in SQL Server. (If you are using a data source other than SQL Server, see the instructions for your data source to create a logon with data-read permissions for the data access account.)

To create a SQL Server logon for the data access account
  1. In SQL Server Management Studio, connect to the database engine.

  2. In Object Explorer, expand Security.

  3. Right-click Logins, and then click New Login.

  4. In the Login name box, type the name of the Active Directory account that you created for data access.

  5. In the Select a page section, click User Mapping.

  6. Select the Map check box for the database that you want to provide access to, and then, in the Database role membership for: <database> section, select the db_datareader check box.

  7. Click OK.

Now that you have created a logon for the data access account and granted the account access to your data source, you must create a target application in Secure Store to contain the credentials for the data access account.

The unattended service account configuration is part of the Excel Services Global Settings. Use the following procedure to configure the unattended service account in Excel Services.

To configure Excel Services Global Settings
  1. On the the SharePoint Central Administration website home page, in the Application Management section, click Manage service applications.

  2. On the Manage Service Applications page, click the Excel Services service application.

  3. On the Manage the Excel Services page, click Global Settings.

  4. On the Excel Services Settings page, in the External Data section:

    • Select the Create a new Unattended Service Account option.

    • Type the user name and password of the account that you created for data access.

  5. Click OK.

With the Excel Services Global Settings configured, setup of the unattended service account is complete. The next section describes how to configure the Excel Services authentication settings in a data-connected Excel workbook to refresh the data with the unattended service account after the workbook has been published to a SharePoint document library.

You must configure the Excel Services Authentication Settings in the workbook before you publish it to SharePoint Server 2013. Doing so enables the workbook to use the unattended service account to refresh data when the workbook is rendered in Excel Services. Use the following procedure to configure the authentication settings.

To configure Excel Services authentication settings
  1. In a data-connected Excel workbook, on the Data tab, click Connections.

  2. On the Workbook Connections dialog box, select the data connection that you want to update, and then click Properties.

  3. On the Connection Properties dialog box, on the Definition tab, click Authentication Settings.

  4. On the Excel Services Authentication Settings dialog box, select the None option, and then click OK.

  5. On the Connection Properties dialog box, click OK.

    NoteNote:
    If you see a warning that the link to the external connection file will be removed, click Yes.
  6. On the Workbook Connections dialog box, click Close.

With the Excel Services Authentication Settings set to None, Excel Services uses the unattended service account to refresh the data in the workbook after you have published it to SharePoint Server 2013.
