Abstract:

    IIS Services IISADMIN Extension
    Main COM interface.
    Class CadmExt
    
    CLSID = CLSID_SSLCONFIGPROV
    IID = IID_IADMEXT

    extension is used to launch SSL CONFIGURATION PROVIDER in the inetinfo
    that would enable strmfilt.dll to connect to named pipes and retrieve
    metabase data rather than using COM based metabase (ABO).
