SharePoint 2010–Set custom sign in page

this one took me several hours. So much crap on Google but no solution anywhere.

If your SharePoint site is using Classic Mode Authentication

$webappurl = 'https://web.site.com'
Set-SPCustomLayoutsPage -Identity Login -RelativePath "/_layouts/something/login.aspx" -WebApplication $webappurl

To remove it again use

$webappurl = 'https://web.site.com'
Set-SPCustomLayoutsPage -Identity Login -reset -WebApplication $webappurl

If how ever your site is using Claims Based Authentication this wont work. Then use

$webappurl = 'https://web.site.com'
Set-SPWebApplication $webappurl -zone Default -SignInRedirectURL "/_layouts/wingu.SharePoint.Authentication/login.aspx"

And to remove it (reset it) again use

$webappurl = 'https://web.site.com'
Set-SPWebApplication $webappurl -zone Default -SignInRedirectURL ""

And a not to my self on how to do it on all websites

get-SPWebApplication | foreach-object {
    $_
    $ap1 = Get-SPTrustedIdentityTokenIssuer
    $ap2 = New-SPAuthenticationProvider -UseWindowsIntegratedAuthentication
    Set-SPWebApplication $_.Url -AuthenticationProvider $ap1, $ap2 -zone Default -SignInRedirectURL "/_layouts/wingu.SharePoint.Authentication/login.aspx"
}
