如何使用PowerShell在CSV文件中获取用户的到期日期？

Question

Import-CSV -Path .\csv_file.csv | ForEach-Object { 
    Get-ADUser -filter {Enabled -eq $True -and PasswordNeverExpires -eq $False} –Properties “DisplayName”, “msDS-UserPasswordExpiryTimeComputed” |
    Select-Object -Property “Displayname”,@{Name=“ExpiryDate”;Expression={[datetime]::FromFileTime($_.“msDS-UserPasswordExpiryTimeComputed”)}}
} | Export-Csv .\results.csv -NoTypeInformation

This works great but gets all USERS in AD. We have thousands of Users.

I want to get users that are in a CSV file (1st column). If possible, I'd love to create a second column in the same file with the expiration date.

I modified my PowerShell Script but not sure how to get the value from the CSV file into Get-ADUser

Answer 1

With a samaccountname header in the csv file:

Import-CSV -Path C:\folder\input.csv | ForEach-Object { 
    Get-ADUser -Identity $_.samaccountname –Properties DisplayName,msDS-UserPasswordExpiryTimeComputed,Enabled,PasswordNeverExpires | Select-Object -Property Displayname,Enabled,PasswordNeverExpires,@{Name="ExpiryDate";Expression={[datetime]::FromFileTime($_."msDS-UserPasswordExpiryTimeComputed")}}
} | Export-CSV C:\folder\results.csv -NoTypeInformation
