Reducing Splunk authentication storms

Splunk authentication is destroying my Active Directory because of frequency of authentications, our user search dn contains 100000 users, our DC's are logging around 2.5 million authentication queries a day from the Splunk service account, I have some suspicions that it is around the cache configuration, can anyone offer some advice on how to reduce this auth storm (only a 10-20 people use the app per day).
