People Picker takes too long to resolve names

People Picker takes too long to resolve names 

 

This is a most common issue that we see in People search that picker takes more time to resolve the names. Microsoft has provided a fix for this. There is not impact and no downtime.

Issue: People Picker takes too long to resolve names

Cause: The problem is that we will always go to Active Directory first by default to do the lookup via the Translate To ids  function.  This isn’t desirable in this specific case because it’s a SharePoint security group that’s being passed.  The second part of the problem is with the format of the name specified on the people picker field.  The fact that there is no \ in the name causes Active Directory to submit the lookup against every domain in the forest.  In a large Forest, this can become a taxing operation.  Finally, the lookup is resolved within SharePoint.

Solution: Please run the following to resolve the issue.

1.    [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint")

2.    $webapp=[Microsoft.SharePoint.Administration.SPWebApplication]::Lookup("WEB App URL")

3.    $webapp.PeoplePickerSettings.ActiveDirectoryRestrictIsolatedNameLevel=$true;

4.    $webapp.Update();
