#PSTip Adding local users to SQL Server Logins using SMO

Note: This tip requires PowerShell 2.0 or above.

There was a question on StackOverflow about adding local users to SQL Server logins. I provided an answer to that and realized from a user’s comment that the SMO method to create a SQL login works only in a specified manner.

So, in this tip, I will show you the SMO way of adding local users to SQL Server logins.

Add-Type -AssemblyName "Microsoft.SqlServer.Smo, Version=, Culture=neutral, PublicKeyToken=89845dcd8080cc91"
Add-Type -AssemblyName "Microsoft.SqlServer.ConnectionInfo, Version=, Culture=neutral, PublicKeyToken=89845dcd8080cc91"

$conn = New-Object Microsoft.SqlServer.Management.Common.ServerConnection -ArgumentList $env:ComputerName
$conn.applicationName = "PowerShell SMO"
$conn.ServerInstance = ".\SQLEXPRESS"
$conn.StatementTimeout = 0
$smo = New-Object Microsoft.SqlServer.Management.Smo.Server -ArgumentList $conn
$SqlUser = New-Object -TypeName Microsoft.SqlServer.Management.Smo.Login -ArgumentList $smo,"${env:ComputerName}\JohnDoe"
$SqlUser.LoginType = 'WindowsUser'
$sqlUser.PasswordPolicyEnforced = $false

In the above code snippet, observe the way we specified (line 10) the username for the login. It needs to be prefixed with the computer name and not just ‘localhost’.
