Unexpected Results in LDAP Policies

In troubleshooting an issue with a third party application which uses AD authentication, I needed to check the MaxConnections in the LDAP policies. I found that MaxConnections was set to the default of 5000, so that was exactly as expected.

However, in checking these policies using ntdsutil,  I noticed some settings which are not at default on our DCs:

MaxDatagramRecv = 1024 (default 4096)

MinResultSets = 0 (default 3)

MaxResultSetsPerConn = 0 (default 10)

MaxValRange = 0 (default 1500)

MinResultSets = 0 (default 3)

MaxBatchReturnMessages = 0 (default 1100)

We have a Windows 2012 R2 domain/forest functional level. It began long ago as a Windows 2000 domain, then to 2003, 2008 R2, 2012 R2.

I'm hoping someone can answer as to whether these values can be expected in our scenario.
