Huh? What does DTML buy you here? You're jus tusing parents, which is crummy...
Why the skip unauthorized? Why the -4 slice?

Still, if you really wanted to use parents:

<tal:i define="parents request/PARENTS"
        repeat="i range(len(parents)-4,0,-1)">

<a tal:define="item parents/?i"
    tal:attributes="href item/absolute_url"
    tal:content="item/title_or_id"/>

<tal:c condition="not:repeat/i/end">
&nbsp;&gt;&nbsp;
</tal:c>

</tal:i>

cheers,

Chris
