Symptoms

Assume that you run Setspn.exe and use the –X switch and the –F switch to identify duplicate Service Principal Names (SPNs) in Windows 8 or Windows Server 2012 in a domain forest. In this situation, you may encounter a time-out error. For example, you may receive an error message that resembles the following:
Checking forest DC=corp, DC=contoso, DC=com
Operation will be performed forestwide, it might take a while.
Ldap Error(0x55 -- Timeout): ldap_get_next_page_s <Date/Time>

The tool queries 100 objects in a paged query and is counting the pages on screen when you omit the -P option. When the problem does not happen always, you will notice that the problem will always occur on the last page.

Note This issue typically occurs when there are tens of thousands to hundreds of thousands of SPNs in the forest.

Cause

This issue occurs because the SPN query times out after one minute.

The last page of the query is slow as the LDAP server needs to ensure there are no duplicate objects returned. Towards the end of the query most objects are suppressed as they were returned previously for other hits in the servicePrincipalName attribute.

Status

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

More information

The update sets the query time-out to three minutes. So with a default "MaxQueryDuration" LDAP Server Policy of two minutes, this policy will be in effect next to abort the query if it runs for an extended time. You may want to extend the server policy time-out when you are affected by the limit of two minutes.
