[Mailman-Users] private archives authentication

[Daniel Barna]

Hello
I tried to set up mailing lists using mailman on SuSE-9.2 (my own mailman
installation, not the SuSE package)
 Everything works fine, but I can not access the private archives of the
lists using the url http://some.host.com/mailman/private/listname
when I enter a valid e-mail address and password for the given list, the
same login page is returned.
Does anyone have an idea why?
thanks
Daniel
