Get userID using CSOM powershell

Question

I want to get the User ID using PowerShell CSOM

I know its $replacedUser =$web.EnsureUser("domainName\Account") server side but I don't know how to do it client side

Answer 1

Should work more or less the same:

$identity = $web.EnsureUser($user)
$ctx.Load($identity)
$ctx.ExecuteQuery()

Answer 2

$Context = New-Object Microsoft.SharePoint.Client.ClientContext($SiteURL)
$replacedUser =$Context.Web.EnsureUser(domain\USER)

this worked
