The new plug-in class will extend the com.iplanet.am.sdk. AMUserPasswordValidation class and implement the validateUserID() and validatePassword() methods. AMException should be thrown if validation fails.
Compile the plug-in class and place the .class file in the desired location. Update the classpath so that it is accessible by the Access Manager during runtime.
Login to the Access Manager console as top-level administrator. Click on the Service Management tab, and get to the attributes for the Administration Service. Type the name of the plug-in class (including the package name) in the UserID & Password Validation Plugin Class field.
Logout and login.
