If you want to use Workflows in your Microsoft SharePoint 2013 environment, you need to install SharePoint 2013 Workflow Manager. You can install the Workflow Manager either on a server that is also running SharePoint or on a separate server and communication between SharePoint is both possible over HTTP and HTTPS. This article on TechNet describes how to install the Workflow Manager.
However, during the installation of the of the Workflow Manager on your (development) environment, can might receive the following error:
Could not obtain information about the Windows NT group/user ‘Domain\ServiceAccount’, error code 0x6e.
Where ‘Domain\ServiceAccount’ is the account configured to run the service.
The reason you receive this error is because SQL Server is not able to obtain information about the specified account;
1) You run the SQL Server Instance as a local user; for example: "NT SERVICE\MSSQL$SharePoint"
2) The SQL Server instance account is not privileged to read the Active Directory.
Either way, you can change the user account prior to installation to another user account, complete the installation of the Workflow Manager, and then revert back to the original account.
