Appendix E Installing and Configuring Kerberos Setup Service

The Kerberos Setup Service (KSS) program runs on the Key Distribution Center (KDC) server. The KSS can be used optionally to administer Spectrum24 access points authorized on the network. For example, an AP on the Access Control List (ACL) is lost or stolen. The KSS marks the AP (using the MAC address of the AP) as not authorized and notifies the administrator if the missing AP appears elsewhere on the network attempting authentication. All clients (MUs), KDC and services (APs) participating in the Kerberos authentication system are required to have their internal clocks synchronized within a specified maximum amount of time (known as clock skew). The KSS uses Network Time Protocol (NTP) or the system clock on the Kerberos server to provide clock synchronization (timestamp) between the KDC and APs as part of the authentication process. Clock synchronization is essential since the expiration time is associated with each request for resources. If the clock skew is exceeded between any of the participating hosts, requests are rejected.

Additionally, the KSS provides a list of authorized APs and other security setup information that the KDC uses to authenticate clients. When setting up the KSS, assign APs an ESSID to authenticate with the KDC. In Open Enrollment mode, the KSS dynamically creates an AP Setup Account for the AP and creates a Kerberos account with the KDC. The KSS continues to do this until the administrator disables Open Enrollment.

For additional information on KSS and KDC functionality, refer to the sections of this document.
