为什么我收到“密钥凭证开始日期无效。”尝试创建 Active Directory 服务主体

我一直在尝试整合一系列围绕创建和刷新 AD 服务主体和应用程序的操作。我遇到问题的流程是：

1. 从 Azure Key Vault 获取证书
2. 使用证书进行身份验证创建服务主体（和应用程序）。

PS > Get-AzureKeyVaultCertificate -VaultName certs -Name CertName

Name        : CertName
Certificate : [Subject]
                CN=certName.foo.com

              [Issuer]
                CN=certName.foo.com

              [Serial Number]
                xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

              [Not Before]

为什么我得到密钥凭证开始日期无效?

根据您的错误日志，似乎时间格式错误。我建议你可以使用[System.DateTime]::Now设置时间。我在实验室进行测试，没有遇到您的错误日志，以下脚本对我有用。我建议你可以测试一下。

##import certificate to key valut
$Password = ConvertTo-SecureString -String "*******" -AsPlainText -Force
Import-AzureKeyVaultCertificate -VaultName "shuikey" -Name "ImportCert01" -FilePath "C:\shui.pfx" -Password $Password
##set start time and expire time
$now = [System.DateTime]::Now
$yearfromnow = $now.AddYears(1)
##Get certificate from key vault
$cert=Get-AzureKeyVaultCertificate -VaultName certs -Name CertName

New-AzureRmADServicePrincipal -DisplayName "Cert access" -CertValue $([System.Convert]::ToBase64String($cert.Certificate.GetRawCertData())) -StartDate $now -EndDate $yearfromnow
