  • Hello,

    AAD and AD users are joined and identified by a Attribute called sourceAnchor/ImmutableID, which is a simple Base64Encode of the ADs ObjectGUID.

    So simple get the ObjectGUID of the user in local AD, do a Base64Encode and search AAD for the user where this value matches the ImmutableID.

    Here is some sample code for the Encode with PS from my blog:

    $GUIDbyte = (Get-ADUser peter).objectGUID.ToByteArray()
    $immuID = [System.Convert]::ToBase64String($GUIDbyte)
