When I setup my sitemap in asp.net, how can I define within the site map that this particular menu should only be displayed if the person is logged in?

And in roles="*", what are the other possible values? How does that work?

you would need to use Membership to control what the user has access to and then the SiteMap Menu will be security trimmed acordingly.

See the extract below from my web.config

      <location path="admin/Gallery">
            <system.web>
                  <authorization>
                        <allow roles="adminPhotos"/>
                        <deny users="*"/>
                  </authorization>
            </system.web>
      </location>

The above will only allow users who are in the role adminPhotos access to the area ~/admin/Gallery. All other things in the site (asp:Menu etc) will automatically security trim.

How are your users logging into the site do you use Forms Auth?

I should have said you need to use Membership and RolesProviders and a Secured SiteMap, see bellow for another snip from my web.config

            <membership defaultProvider="AccessMembershipProvider">
                  <providers>
                        <clear/>
                        <add name="AccessMembershipProvider" type="Samples.AccessProviders.AccessMembershipProvider" connectionStringName="ASPNetDB" enablePasswordRetrieval="false" enablePasswordReset="true" requiresUniqueEmail="true" requiresQuestionAndAnswer="false" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" applicationName="RAdmin" hashAlgorithmType="SHA1" passwordFormat="Hashed"/>
                  </providers>
            </membership>
            <roleManager enabled="true" cacheRolesInCookie="true" defaultProvider="AccessRoleProvider">
                  <providers>
                        <add connectionStringName="ASPNetDB" applicationName="RedsAdmin" name="AccessRoleProvider" type="Samples.AccessProviders.AccessRoleProvider"/>
                  </providers>
            </roleManager>
            <siteMap enabled="true" defaultProvider="SecuredSiteMapProvider">
                  <providers>
                        <clear/>
                        <add name="SecuredSiteMapProvider" description="Default SiteMap provider." type="System.Web.XmlSiteMapProvider " siteMapFile="Web.sitemap" securityTrimmingEnabled="true"/>
                  </providers>
            </siteMap>

As you can see I use the Access provider, if you are using Sql Server your code will differ slightly. However the concert still applies.

well, I guess I'll have to take your word for it, since I can't test it at this point. :)

thanks!

As an alternative to this you can show/hide menu items in the Databound event of the asp:menu. in this you can use "User.Identity.IsAuthenticated" and you wouldn't need any of what I have suggested above. If you need more info, ask and I'll find the solution I have provided to others before.
