ActiveDirectory Control
Properties Methods Events Configuration Settings Errors
The ActiveDirectory control can be used to authenticate users against Active Directory using Kerberos 5.0.
Syntax
ActiveDirectory
Remarks
The ActiveDirectory control authenticates users against Active Directory. Authentication is performed using the Kerberos protocol defined in RFC 1510 and RFC 4120.
Authentication
When Authenticate is called the control will attempt to authenticate the user with the Active Directory server. The control will communicate with the ADHost 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 ADHost can be seen through the PITrail event.
