LDAP to DoD Server?

Get this, I just completed a fresh install of Mavericks on a Mac Pro - 4,1.

No more than to hours have gone by, I'm watching the traffic logs on my network firewall and what do I see?

The fresh install attempts multiple LDAP (tcp/389) connections to a couple DoD servers.

Specifically:

I did a WHOIS on 156.112.110.122 and 156.112.102.122

They both resolve to: crl.gds.disa.mil

...Now, 'DISA' stands for Defense Information Systems Agency. DISA is a cousin of the NSA - National Security Agency

I then traversed to https://crl.gds.disa.mil and was presented with:

As you can see, this server is FOUO (For Official Use Only). Why the heck is my fresh install Mavericks machine trying to talk to this guy? Anybody?
