Allow users from another domain to appear in SharePoint 2013 People Picker

SharePoint 2013 Enterprise is installed on Domain1.com and I want users from Domain2 to appear in People Picker. I believe AD level trust is already created because if I give access to "Everyone" on a page/list/library then users from Domain2 can also access it. Only problem is they are not appearing in People Picker.

I found steps in PowerShell to do it but I am not sure if I am doing it right so came here to clarify. 

$wa = Get-SPWebApplication http://webAppUrl  
$adsearchobj = New-Object Microsoft.SharePoint.Administration.SPPeoplePickerSearchActiveDirectoryDomain  
$userpassword = ConvertTo-SecureString "UserPassword1" -AsPlainText -Force #Password for the user account CONTOSO\s-useraccount  
$adsearchobj.DomainName = "contoso.com"  
$adsearchobj.ShortDomainName = "CONTOSO" #Optional  
$adsearchobj.IsForest = $true #$true for Forest, $false for Domain  
$adsearchobj.LoginName = "s-useraccount"  
$adsearchobj.SetPassword($userpassword)  
  
$wa.PeoplePickerSettings.SearchActiveDirectoryDomains.Add($adsearchobj)  
$wa.Update()

I am confused as to which user is "s-useraccount" and its password in above PowerShell. Is the user available on Domain1 or Domain2?

    Hi @Frank Martin ,
    1.You need to first establish a trust relationship between the two domains. Then Configure People Picker in SharePoint 2013.

    2.Then run the following command for each of your web applications, substituting the example URL and domains with your web application URL, local and trusted domain and/or forest.For a full forest trust:

     stsadm -o setproperty -pn peoplepicker-searchadforests -pv "forest:MY-DOMAIN.local;forest:TRUSTED-DOMAIN.local;domain:MY-DOMAIN.local;domain:TRUSTED-DOMAIN.local" -url http://my-sp-site.com.au/
