Sharepoint 2013 filling up my Domain Controller's Security Logs

I just bought and implemented Solarwinds' Syslog server. Good stuff. Now I just need to find the time to look at them! :P

In the process of looking through my domain controllers' security logs (just the failure audits) I was inundated with failures from my Sharepoint server. It made the rest of the logs unreadable, so my goal was set: I needed to fix the Sharepoint server and make it stop doing this!

Here's what the errors look like:

2014-01-22 14:46:13 Kernel.Critical dc02.contoso.com Jan 22 14:46:13 dc02.contoso.com MSWinEventLog 2 Security 12451 Wed Jan 22 14:46:13 2014 4769 Microsoft-Windows-Security-Auditing N/A Audit Failure dc02.contoso.com 14337 A Kerberos service ticket was requested.

It's happening on multiple "client ports":

56594

56605

56607

56624

56643

etc.

Thankfully, I was able to track down a guide on configuring Sharepoint kerberos authentication. No, my logs are cleared up and I can see the data that I care about!
