无法在 Powershell 上使用私有证书连接到 Exchange Online

Question

我正在尝试使用下一个流程创建 powershell 脚本。

通过应用程序登录到 Azure Active Directory。
创建私有证书。
将证书上传到 Azure AD 应用程序证书。
连接到 ExchangeOnline。

为此，我根据以下步骤创建了下一个脚本：第一步：

$clientId = 'xxx'
$tenantId = 'xxx'
$clientSecret = 'xxx'
$org = 'xxx.onmicrosoft.com'
$clientSecret = ConvertTo-SecureString $clientSecret -AsPlainText -Force
$credObject = New-Object System.Management.Automation.PSCredential ($clientId, $clientSecret)
Connect-AzAccount -Credential $credObject -Tenant $tenantId -ServicePrincipal

第 2 步和第 3 步：

$cert = New-SelfSignedCertificate -DnsName $org -NotAfter (Get-Date).AddYears(1) -KeySpec KeyExchange
$binCert = $cert.GetRawCertData()
$credValue = [System.Convert]::ToBase64String($binCert)
$validFrom = [datetime]::Parse($cert.GetEffectiveDateString())
$validTo = [datetime]::Parse($pfx.GetExpirationDateString())
$validTo = $validTo.AddDays(-1);
New-AzADAppCredential -ApplicationId $clientId -CertValue $credValue -StartDate $validFrom -EndDate $validTo

到目前为止一切正常。我可以在应用程序的证书列表中看到此证书。但是当我要使用此命令连接到 MS Exchange Online 时：

Connect-ExchangeOnline -Certificate $cert -AppID $clientId -Organization $org

我收到下一期：

{
   "error":"invalid_client",
   "error_description":"xxx: Client assertion contains an invalid signature. [Reason - The key used is expired., Thumbprint of key used by client: 'xxx', Found key 'Start=03/11/2021 14:59:26, End=03/11/2022 13:09:26', Please visit the Azure Portal, Graph Explorer or directly use MS Graph to see configured keys for app Id 'xxx'. Review the documentation at https://docs.microsoft.com/en-us/graph/deployments to determine the corresponding service endpoint and https://docs.microsoft.com/en-us/graph/api/application-get?view=graph-rest-1.0&tabs=http to build a query request URL, such as 'https://graph.microsoft.com/beta/applications/xxx']\r\nTrace ID: xxxx\r\nCorrelation ID: xxx\r\nTimestamp: 2021-03-11 13:15:28Z",
   "error_codes":[
      700027
   ],
   "timestamp":"2021-03-11 13:15:28Z",
   "trace_id":"xxx",
   "correlation_id":"xxx",
   "error_uri":"https://login.microsoftonline.com/error?code=700027"
}

但是这个新创建的证书不能过期。我很高兴看到任何想法。堆放了几天。

编辑：我还承认，如果我使用 UI 上传新创建的证书，但不使用此命令：

New-AzADAppCredential -ApplicationId $clientId -CertValue $credValue -StartDate $validFrom -EndDate $validTo

然后我可以用新创建的证书在线交换

Answer 1

问题出在$validTo = $validTo.AddDays(-1);。结果，$validTo早于$cert.NotAfter。

请修改脚本如下：

$cert = New-SelfSignedCertificate -DnsName $org -CertStoreLocation "cert:\LocalMachine\My" -NotAfter (Get-Date).AddYears(1) -KeySpec KeyExchange
$binCert = $cert.GetRawCertData()
$credValue = [System.Convert]::ToBase64String($binCert)
New-AzADAppCredential -ApplicationId $clientId -CertValue $credValue -StartDate $cert.NotBefore -EndDate $cert.NotAfter
