FillSearch maxcount parameter doesn't work

I looked the source of LDAPCP, and found that the maxcount in FillSearch doesn't take affect, why we don't use the maxcount to limit the AD Query?

Hello,
well it's true the threshold is ignored. Here are some reasons to explain why:
  • FillSearch method is rarely called in SharePoint 2013. Actually I think it's only called from central admin.
  • I never received any complain about this causing an actual performance issue, so I never saw the need to honor the threshold
thanks,

Hi Yvand,

Thanks for your reply, regarding to your explanation:
  1. I debug the code and found that every people picker in SharePoint will use FillSearch when searching users.
  2. You're right, the performance is not a problem, since the max size for one query in Active Directory is 1000, but I think it's a function, currently in SharePoint peoplepicker, it will return 1000 results instead of 30 results.
