Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for this method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

This method authenticates the User.

Authentication

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:

  • KRB_AS_REQ -> KDC
  • KRB_AS_REP <- KDC
  • KRB_TGS_REQ -> KDC
  • KRB_TGS_REP <- KDC
  • AuthToken is populated with the constructed KRB_AP_REP message.

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