Just talk

Hello Friends, 

It has been a while that I have posted the blogs, so planning to start again with lots of my experience which I gained in Enterprise IT. 

Request:-

Since, most of the companies are moving to Azure cloud or any public clouds, here I got request from client to convert the "objectguid" to "Immutable ID" because, they wanted to maintain the "ms-ds-consistency guid" for the Sync accounts in Azure. 

Solution:

So, lets power up the Powershell and before that lets also prepare the input file required for the script. 

The input file should have "objectguid" for the provided users. 

Script

Convert objectguid to Immutable ID: -

      )

  

    $list = Import-csv $Inputfile

    "Name,SamaccountName,Mail,Objectguid,ImmutableID" | Out-File output.csv

     foreach ($i in $list){

        

        $guid = [GUID]$i.objectguid

        $bytearray = $guid.tobytearray()

        $immutableID = [system.convert]::ToBase64String($bytearray)

        $immutableID 

        $nam= $i.name

        $sam=$i.samaccountname

        $obj=$i.objectguid

        $mail=$i.mail

        "$nam,$sam,$mail,$obj,$immutableID" | Out-File -Append output.csv

}
