Team,
    LDAP communication to the NPS server should begin communicating with LDAP and get 4400 event IDs.  I have joined the server to the domain, added it to a "IAS" "RAS" group, added the NPS Role, received a Cert, and installed the Cert.  When I check the NPS Logs, I see no LDAP communication.  I see connection attempts to the clients, but of course those get rejected.  
    What am I missing, or what can I check to verify that the NPS server is communicating with the domain controllers?

No Log entries for LDAP communication on a Microsoft NPS Server
