使用PowerShell从AD导入用户

我是powershell新手，需要帮助解决脚本中的一些错误。我基本上正在尝试从Active Directory导入所有用户，我的脚本如下：

#Location the CSV file is being saved.
$csvFileLocation = "C:\ADImport\ADImport.csv"

#Verifies that the AD Module is loaded.  If it is not, checks if it is available, if it is, loads it.

Function Get-ADModule {
    if(-not(Get-Module -Name ActiveDirectory)) {
        if(Get-Module -ListAvailable | Where-Object {$_.Name -eq "ActiveDirectory" }) {
            Import-Module -Name ActiveDirectory
            $true
        } else {
            $false
        }
    } else {
        $true
    }
}

if (Get-ADModule) {
    #Creates the CSV Table Format, change the AD DS TableNames to the CoarseMail TableNames
    $tableFormat = @{ Expression = { $_.GivenName -replace ","," " };Label = "FirstName" },
                   @{ Expression = { $_.SurName -replace ","," " };Label = "LastName" },
                   @{ Expression = { $_.SAMAccountName -replace ","," " };Label = "ID" }
    #Gets AD User Objects that are enabled, and only specified properties for perfomance, filters out specified OU's, filters out objects with no first or last name or EmployeeID.
    Get-ADUser -SearchBase "DC=mydomain,DC=com" -Properties SAMAccountName, GivenName, Surname `
    | Where-Object {
         ($_.GivenName -ne $null) -and
         (($_.GivenName.Length -ne 0) -and ($_.SurName.Length -ne 0))
      } `
    | Select-Object $tableFormat | Export-Csv
    $csvFileLocation -NoType
} else {
    Add-Content ($csvFileLocation + ".txt") "The ActiveDirecotry Powershell Module does not
    exist on this machine."
}

PS C:\Users\benc> C:\Users\benc\Desktop\ADImportTest.ps1
Get-ADUser : Cannot validate argument on parameter 'Filter'. The argument is null or empty.
Supply an argument that is not null or empty and then try the command again.

我得到的错误如下：

#Location the CSV file is being saved.
$csvFileLocation = "C:\ADImport\ADImport.csv"

#Verifies that the AD Module is loaded.  If it is not, checks if it is available, if it is, loads it.

Function Get-ADModule {
    if(-not(Get-Module -Name ActiveDirectory)) {
        if(Get-Module -ListAvailable | Where-Object {$_.Name -eq "ActiveDirectory" }) {
            Import-Module -Name ActiveDirectory
            $true
        } else {
            $false
        }
    } else {
        $true
    }
}

if (Get-ADModule) {
    #Creates the CSV Table Format, change the AD DS TableNames to the CoarseMail TableNames
    $tableFormat = @{ Expression = { $_.GivenName -replace ","," " };Label = "FirstName" },
                   @{ Expression = { $_.SurName -replace ","," " };Label = "LastName" },
                   @{ Expression = { $_.SAMAccountName -replace ","," " };Label = "ID" }
    #Gets AD User Objects that are enabled, and only specified properties for perfomance, filters out specified OU's, filters out objects with no first or last name or EmployeeID.

我不确定我在脚本中的错误在哪里，但如果有任何帮助，我将不胜感激。

请检查Get ADUser的语法-过滤器是必需的参数。添加-Filter{objectClass-eq'user'}，错误将消失。

Get ADUser需要一个筛选器参数，您没有提供该参数。尝试将-Filter*添加到您的通话中，以获得ADUser，并查看这会给您带来什么。请注意，这不是很有效，因为您正在获取所有AD用户对象，然后使用Where对象对其进行过滤。阅读有关Get ADUser的详细帮助，了解如何将Where对象过滤器转换为Get ADUser所需的格式；然后，您将在查询广告时进行筛选，这会更好。此外，PowerShell错误消息往往对确定问题的确切原因非常有帮助。您的问题在错误消息中完全正确。无法验证参数“Filter”上的参数。参数为null或为空。请提供一个不为null或空的参数，然后重试该命令。
