尝试使用脚本批量创建AD用户，并将其添加到CSV文件中列出的组。不知道我错过了什么

# 导入Active Directory模块
Import-Module ActiveDirectory

# 读取CSV文件
$users = Import-Csv -Path "C:\path\to\users.csv"

# 循环遍历CSV文件中的每一行
foreach ($user in $users) {
    # 从CSV文件中获取用户信息
    $username = $user.Username
    $password = $user.Password
    $firstname = $user.FirstName
    $lastname = $user.LastName
    $email = $user.Email
    $groups = $user.Groups -split ","

    # 创建AD用户
    $newUserParams = @{
        SamAccountName = $username
        UserPrincipalName = "$username@domain.com"
        Name = "$firstname $lastname"
        GivenName = $firstname
        Surname = $lastname
        EmailAddress = $email
        AccountPassword = (ConvertTo-SecureString -String $password -AsPlainText -Force)
        Enabled = $true
        PasswordNeverExpires = $true
    }
    New-ADUser @newUserParams

    # 将用户添加到组
    foreach ($group in $groups) {
        Add-ADGroupMember -Identity $group -Members $username
    }
}
