SA08_SQL06: Fetch data from SQL Server failed

ERROR:

The following error may be displayed at the top of the Workflow Conductor Control Panel General Settings page after installing Workflow Conductor 1.5 or 1.5.1 for the first time:

System.ApplicationException: SA08_SQL06: Message Code: SA08_SQL06
Message: Fetch data from SQL Server failed.
Please contact your administrator. at Bamboo.Conductor.AdminManagement.ApplicationPages.GlobalSettings.j() at
Bamboo.Conductor.AdminManagement.ApplicationPages.GlobalSettings.RadGridAD_NeedDataSource
(Object sender, GridNeedDataSourceEventArgs e)

ROOT CAUSE:

Certain Workflow Conductor settings cannot be saved or retrieved until the Workflow Conductor SQL Server and Shared Services account are configured. Once these settings are configured, the error message is no longer displayed.

SOLUTION:

1. Configure the SQL Server setting in the Workflow Conductor Control Panel General Settings page. The SQL Server name must be entered in the format DBSERVER\Instance, referring to the SQL Server and database instance name where the Conductor_Content database is installed.
2. Configure the Shared Services and Deployment accounts in the Workflow Conductor Control Panel Account Settings page. Be sure to enter accounts that meet the permissions requirements described on that page.
