PowerShell自动化核对AD与HR系统账户信息实战指南

news 2025/7/25 11:54:10

作为AD域管理员，您是否曾为员工账户状态与HR系统不一致而头疼？本文将分享一款自动化核对工具，5分钟完成千人规模账户信息校验，杜绝"幽灵账户"和权限残留问题。

一、应用场景与痛点分析

典型问题场景：

离职员工账户未禁用：HR系统已标记离职，AD账户仍活跃
部门调整未同步：员工调岗后OU未更新
姓名信息不一致：中英文名在HR/AD系统存在差异
幽灵账户风险：HR无记录但AD中存在的可疑账户

二、自动化核对脚本详解

# 1. 初始化环境
Import-Module ActiveDirectory
$logPath = "D:\Audit\AD_HR_Check"
$today = Get-Date -Format "yyyyMMdd"
$csvFile = "$logPath\hr_export.csv"
$logFile = "$logPath\ad_hr_check_$today.log"

# 2. 创建日志目录
if (-not (Test-Path $logPath)) {
New-Item -Path $logPath -ItemType Directory -Force
}

# 3. 核心函数：从DN提取组织单位
function Get-OUFromDN {
param([string]$DistinguishedName)
$dnParts = $DistinguishedName -split ','
$ouPart = $dnParts | Where-Object { $_ -match '^OU=' }
if ($ouPart) { return ($ouPart[0] -replace '^OU=', '') }
return "N/A"
}

# 4. 获取待检查的AD账户
try {
$adUsers = Get-ADUser -Filter {
SamAccountName -like "6*" -or
SamAccountName -like "9*"
} -Properties DistinguishedName, Enabled, DisplayName, sn
} catch {
"ERROR: 获取AD用户失败 - $_" | Out-File -Append $logFile
exit
}

# 5. 导入HR系统数据
try {
$hrData = Import-Csv $csvFile -Encoding UTF8
$hrHash = @{}
$hrData | ForEach-Object { $hrHash[$_.EmployeeID] = $_ }
} catch {
"ERROR: CSV导入失败 - $_" | Out-File -Append $logFile
exit
}

# 6. 双向比对逻辑
$mismatches = @()

# 6.1 检查AD账户是否匹配HR记录
foreach ($user in $adUsers) {
$id = $user.SamAccountName
$adStatus = $user.Enabled
$adOU = Get-OUFromDN $user.DistinguishedName

if (-not $hrHash.ContainsKey($id)) {
# 处理HR系统中不存在的AD账户
$mismatches += [PSCustomObject]@{
EmployeeID = $id
AD_Status = if($adStatus){"Enabled"}else{"Disabled"}
HR_Status = "Not in HR"
AD_OU = $adOU
HR_OU = "N/A"
NameMatch = "N/A"
Result = "Orphan Account"
}
} else {
# 详细比对各项属性
$hrRecord = $hrHash[$id]
$statusMatch = ($hrRecord.Status -eq "Active") -eq $adStatus
$ouMatch = ($adOU -eq $hrRecord.Department)
$nameMatch = ($user.DisplayName -eq $hrRecord.EnglishName) -and
($user.sn -eq $hrRecord.ChineseName)

if (-not ($statusMatch -and $ouMatch -and $nameMatch)) {
$mismatches += [PSCustomObject]@{
EmployeeID = $id
AD_Status = if($adStatus){"Enabled"}else{"Disabled"}
HR_Status = $hrRecord.Status
AD_OU = $adOU
HR_OU = $hrRecord.Department
NameMatch = $nameMatch
Result = "Data Mismatch"
}
}
}
}

# 6.2 检查HR记录是否在AD中存在
foreach ($hrRec in $hrData) {
$id = $hrRec.EmployeeID
if ($adUsers.SamAccountName -notcontains $id) {
$mismatches += [PSCustomObject]@{
EmployeeID = $id
AD_Status = "Not in AD"
HR_Status = $hrRec.Status
AD_OU = "N/A"
HR_OU = $hrRec.Department
NameMatch = "N/A"
Result = "Missing Account"
}
}
}

# 7. 输出审计结果
if ($mismatches) {
$mismatches | Export-Csv "$logPath\mismatches_$today.csv" -NoTypeInformation
"发现 $($mismatches.Count) 条不一致记录" | Out-File -Append $logFile
} else {
"所有账户信息一致" | Out-File -Append $logFile
}

三、核心功能解析

1. 智能组织单位提取

function Get-OUFromDN {
param([string]$DistinguishedName)
$dnParts = $DistinguishedName -split ','
$ouPart = $dnParts | Where-Object { $_ -match '^OU=' }
if ($ouPart) { return ($ouPart[0] -replace '^OU=', '') }
return "N/A"
}

作用：从AD的DN属性中精准提取部门信息，如：
OU=财务部,DC=company,DC=com → 财务部

2. 双向比对策略

比对方向	检测问题类型	风险等级
AD → HR	孤儿账户(Orphan)	⚠️高危
HR → AD	缺失账户(Missing)	⚠️高危
属性交叉比对	状态/部门/姓名不匹配	⚠️中危

3. 结果分类输出

EmployeeID | AD_Status | HR_Status | AD_OU | HR_OU | Result
-----------------|-----------------|----------------|---------------|---------------|---------------
600123 | Enabled | Inactive | 财务部 | 财务部 | 状态不匹配
900456 | Enabled | Active | 技术部 | 市场部 | 部门不匹配
700789 | Disabled | Active | 人事部 | 人事部 | 状态不匹配

四、部署使用指南

步骤1：环境准备

HR系统定期导出CSV（含字段：EmployeeID, Status, Department等）
在AD服务器安装RSAT工具：

Add-WindowsCapability -Name Rsat.ActiveDirectory.DS-LDS.Tools~~~~0.0.1.0 -Online

步骤2：配置文件调整

# 根据实际环境修改：
$logPath = "D:\Audit\AD_HR_Check" # 审计日志路径
$csvFile = "\\HR-SERVER\export\hr_data.csv" # HR数据路径

# 按需调整账户过滤规则：
Get-ADUser -Filter {
SamAccountName -like "6*" -or
SamAccountName -like "9*"
}

步骤3：自动化任务设置

# 创建每日任务
$trigger = New-JobTrigger -Daily -At 2am
Register-ScheduledJob -Name "AD-HR审计" `
-FilePath "D:\Scripts\AD_HR_Audit.ps1" `
-Trigger $trigger

五、典型问题处理方案

场景1：发现孤儿账户

# 自动禁用孤儿账户
Import-Csv "D:\Audit\mismatches_202405.csv" |
Where-Object { $_.Result -eq "Orphan Account" } |
ForEach-Object {
Disable-ADAccount -Identity $_.EmployeeID
Set-ADUser -Identity $_.EmployeeID -Description "自动禁用:孤儿账户"
}

场景2：部门信息不一致

# 同步部门信息
$corrections = Import-Csv "D:\Audit\dept_mismatches.csv"
foreach ($item in $corrections) {
$user = Get-ADUser -Filter "SamAccountName -eq '$($item.EmployeeID)'"
$newOU = "OU=$($item.HR_OU),DC=company,DC=com"
Move-ADObject -Identity $user.DistinguishedName -TargetPath $newOU
}

六、企业级增强方案

1. 邮件通知集成

# 审计完成后发送邮件
$body = "发现 $($mismatches.Count) 个问题账户`n详细报告见附件"
Send-MailMessage -To "admin@company.com" `
-Subject "AD-HR审计警报" `
-Body $body `
-Attachments "$logPath\mismatches_$today.csv"

2. 与IAM系统集成

# 将问题账户同步到IAM平台
$issues | ForEach-Object {
Invoke-RestMethod -Uri "https://iam-api/issue" `
-Method POST `
-Body ($_ | ConvertTo-Json)
}

3. 历史趋势分析

# 生成月度审计报告
$monthlyData = Import-Csv "D:\Audit\mismatches_*.csv"
$trend = $monthlyData | Group-Object Month, ResultType |
Select-Object Name, Count |
Export-Csv "年度审计趋势.csv"
