Read txt line by line and query AD

Question

I have a text file containing samids:

XXXXXXX
YYYYYYY
ZZZZZZZ

For each one I need to read it quering AD with this:

dsquery user         


        

Answer 1

Use Get-ADUser from the ActiveDirectory PowerShell module instead of the ds tools:

Import-Module ActiveDirectory

Get-Content 'C:\path\to\input.txt' |
  Get-ADUser -SearchBase 'DC=example,DC=org' -Property mail |
  select -Expand mail | Out-File 'C:\path\to\output.txt'

Where DC=example,DC=org is the distinguished name (DN) of your forest root domain.

For programmatically determining the DN of the forest root domain you could use this:

([ADSI]"LDAP://RootDSE").RootDomainNamingContext
