AD Control
Properties Methods Events Configuration Settings Errors
The AD component can be used to authenticate users against Active Directory using Kerberos 5.0.
Syntax
AD
Remarks
The AD control authenticates users against Active Directory. The control implements the Kerberos protocol defined in RFC 1510 and RFC 4120. Thecontrol provides a simple interface to easily authenticate users.
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.
