I have a custom resource which runs a SQL script on SQL server. Script runs using machine account where I run DSC, I need to run this as a different account. I dont want to use sql authentication.
Below is set function of my resource code. Right now this script runs as domain\MAchineName$ I need to run it as different user e.g domain\dvapp
$sql = [Io.File]::ReadAllText($SqlScriptPath)
$SqlConnection = New-Object System.Data.SqlClient.SqlConnection
$SqlConnection.ConnectionString = $ConnectionString
$Command = New-Object System.Data.SQLClient.SQLCommand
# Set the SqlCommand's connection to the SqlConnection object above.
$Command.Connection = $SqlConnection
# Set the SqlCommand's command text to the query value passed in.
$Command.CommandText = $sql
# Execute the command against the database without returning results (NonQuery).
I believe your best and Microsoft supported option would be to use the PsDscRunAsCredential property introduced with WMF/PowerShell 5.0. The only caveat is you need to get all your DSC nodes updated to at least the Windows Management Framework (WMF) 5.0.
