PowerShell - New-SPWeb with UniquePermissions

I want to create a new SPWeb with PowerShell. My code creates the site and add the group to the site but not the user "TestUser1". The test\testuser1 belongs not to the TestGroup1 and get intepend permissions.

 $web = New-spweb http://http:/mysharepointurl/site/web -Template "STS#0" -UniquePermissions 

$user = $web.EnsureUser('test\testuser4')

$web.Users.AddUser($user, "Full") #Not working, Add a 开发者_如何学编程existing User

$newGroup = $web.SiteGroups["TestGroup6"] #Working, Add a existing Group
$web.Roles["Full"].AddGroup($newGroup)

Have you tried

$web.Users.Add -or- $web.AllUsers.Add

public void Add(
    string loginName,
    string email,
    string name,
    string notes
)

You are using New-SPWeb, so that means you need to be adding users to the SPWeb.

$web.SiteUsers is the site collection group

You should use

$web.Users

My working solution:

$web = Get-SPWeb "http://http:/mysharepointurl/site/web" 
$user = $web.AllUsers["test\testuser1"]
$roledef = $web.RoleDefinitions["Vollzugriff"]
$roleass = New-Object Microsoft.SharePoint.SPRoleAssignment($user)
$roleass.RoleDefinitionBindings.Add($roledef)
$web.RoleAssignments.Add($roleass)
$web.Update()

Thanks for the support!
