NavBar in SiteDefinition

Question

I have created a site definition for my project. In this site definition I create two list instances of the same template by using the tag <List> of the site definition itself.

<Lists>
    <List Title="List1" Type="50001" Url="Lists/List1" FeatureId="{174CE875-9EF0-4C93-87E6-B33BDEB1899F}" />
    <List Title="List2" Type="50001" Url="Lists/List2" FeatureId="{174CE875-9EF0-4C93-87E6-B33BDEB1899F}" />
</Lists>

During site provision I setup different security for these lists. E.G. List1 is only accessible from Group 1 which has collaboration permissions while List2 is only accessible from Group 2 with collaboration permissions

I have then created a couple of links in the NavBar section of the site definition

<NavBars>
    <NavBar Name="Archives" Url="#" ID="1501">
        <NavBarLink Name="My Archive" Url="Lists/List1/AllItems.aspx"></NavBarLink>
        <NavBarLink Name="My Archive" Url="Lists/List2/AllItems.aspx"></NavBarLink>
    </NavBar>
</NavBars>

I expected that, depending on the connected user on of the two links would disappear but this is'nt true. The links are always both visible, however one of the two, depending on the connected user, would generate an Acces Denied when clicked.

Where am I doing wrong?
