SiteMap control based on user roles doesn't works

  <siteMapNode roles="*">

    <siteMapNode url="~/Default.aspx" title=" Main"开发者_运维百科 description="Main" roles="*"/>

    <siteMapNode url="~/Items.aspx" title=" Adv" description="Adv" roles="Administrator"/>

....

any user can see Adv page. That is a trouble and a qustion : why and how to hide out of role sitenodes.

but if I do HttpContext.Current.User.IsInRole("Administrator") it shows me if user in Administrator role or not.

web config :

<authentication mode="Forms"/>
<membership defaultProvider="SqlProvider" userIsOnlineTimeWindow="20">
  <providers>
    <add connectionStringName="FlowWebSQL" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="true" passwordFormat="Hashed" applicationName="/" name="SqlProvider" type="System.Web.Security.SqlMembershipProvider"/>
  </providers>
</membership>
<roleManager enabled="true" defaultProvider="SqlProvider">
  <providers>
    <add connectionStringName="FlowWebSQL" name="SqlProvider" type="System.Web.Security.SqlRoleProvider" />
  </providers>
</roleManager>

Enable security trimming Security trimming is not enabled by default, and it cannot be enabled programmatically; it can only be set in the Web.config file

You need to use location tag in web.config.

<location path ="Items.aspx" >

   <system.web>

     <authorization>

       <allow roles ="Administrator"/>
       <deny users="*"/>
     </authorization>

   </system.web>

 </location>
