Modifying Configuration Information in the User Interface
An attachment snap-in extension must allow the user to modify configuration information about the service. The modified information should be stored by the attachment snap-in extension until the Security Configuration snap-in calls methods of the ISceSvcAttachmentPersistInfo interface to retrieve the information.
To avoid memory leaks, free memory allocated by the snap-in extension by calling ISceSvcAttachmentPersistInfo::FreeBuffer.
