Kerberos Class

Properties   Methods   Events   Configuration Settings   Errors  

The Kerberos class can be used to authenticate users using Kerberos 5.0.




The Kerberos class implements the Kerberos protocol defined in RFC 1510 and RFC 4120. The class provides a simple interface to easily authenticate users.


When Authenticate is called the class will attempt to authenticate the user with the Key Distribution Center (KDC). The class will communicate with the KDCHost to obtain a service ticket and populate AuthToken. The following properties are required when calling this method:

A typical sequence of messages would be:

  • AuthToken is populated with the constructed KRB_AP_REP message.

Communication with the KDCHost can be seen through the PITrail event.
