[Zope] Authentication Dialog comes again and again

[Eddy Ilg]

Hi,


I created a website with Zope that has its own acl_user folder with 
different users registered. When I log onto the site everything is fine, 
but by acessing certain pages Zope asks for a login again. Then I enter 
exact the same user and password and I can access the page.

How can I prevent Zope from asking me for this useless login? Why does 
it come up?


Thanks

Eddy
