Just wanted to have it handy for my own reference. Microsoft Kerberos client credentials are obtained from a key distribution center (KDC) and then presented when establishing server connections. When working properly the name is referred to the service vip, which returns and IP address, and the client will connect. Each Active Directory provider must be associated with a groupnet.
