[horde] Horde Imp CAS Authentication

[Laura McCord]

Hi,

I am trying to perform Horde WebMail authentication using CAS. I was 
wondering if this documentation is still relevant  that is found here 
(Horde 3):
http://wiki.horde.org/CASAuthHowTo
http://www.esup-portail.org/display/PROJHORDE/Installation+de+Horde-webmail

Or perhaps, has CAS been integrated in the latest Horde 4 version?

Thanks,
  Laura
