Adding Custom Functionality to ADSI for IIS

  • Article

You can add a custom method, or function, to the IIS ADSI programming model in the form of an ADSI extension. An ADSI extension is a COM object that developers use to extend an ADSI object. Each extension is associated with a specified class in ADSI. With the extension model, developers can give more dynamic meaning to an object by implementing a function in a custom extension, and then binding the extension to the class object they want to extend.
