One of my colleague asked me a PowerShell script to query AD User information! Yes, I did your voice!

Import-Module ActiveDirectory 
Get-ADUser -Identity <samaccountname>

But, he asked “How will I do it in NODE JS with no AD Module?” Well! it’s too deep to discuss about node js! Anyways to make it simple I shared an app which  serves as a REST endpoint to query AD User information from any platforms like ASP.NET , NODE JS, PowerShell etc.

 

var express = require('express');
var shell = require('node-powershell');

var app = express();

var ps = new shell({
    executionPolicy: 'bypass',
    noProfile: true
});

app.get("/:guid", function (req, res) {
    ps.addCommand("./user.ps1", [ {
        name: 'guid', value: req.params.guid
    } ])
    ps.invoke().then(output => {
        console.log(req.params.guid)
        res.end(output);
    })
})

var server = app.listen(8081, function () {

    var host = server.address().address
    var port = server.address().port
    console.log("Example app listening at http://%s:%s", host, port)

})

The PS script for User.PS1 is using ADSI 🙂 with a parameter for samaccountname which is named as GUID (A Friendly Name 🙂 )!

param (
    [Parameter(Mandatory = $true)]
    $guid
)
try {
    $adsi = New-Object adsisearcher 
    $propstoLoad = @("givenname" , "sn" , "samaccountname" , "mail");
    $adsi.PropertiesToLoad.AddRange($propstoLoad)
    $adsi.Filter = "(&(ObjectCategory=User)(samaccountname=$guid))"
    $result = $adsi.FindOne().Properties
    [pscustomobject]@{
        GivenName = $result['givenname'] -as [string]
        SurName   = $result['sn'] -as [string]
        GUID      = $result['samaccountname'] -as [string]
        mail      = $result['mail'] -as [string]
    } | ConvertTo-Json
}
catch {
    $_.Exception
}

Spin your NODE and browse for the result!  REST URL : http://127.0.0.1:8081/ChenV

{
    "GivenName":  "Chendrayan",
    "SurName":  "Venkatesan",
    "GUID":  "ChenV",
    "mail":  "chendrayan.venkatesan@contoso.com"
}

The RESTful continues! Happy PowerShell!
