Start with the sql-server-2014-alwayson-existing-vnet-and-ad template and its xSqlEndpoint configuration. Inspect CreateFailoverCluster.ps1 at the reported line 273 and review the Microsoft-Windows-DSC/Operational log for the CreateCluster extension. Done means the template deployment completes without the xSqlEndpoint binding error.
