[horde] Problems setting up horde

[xare]

Hello everybody

I am trying to set up horde and all its components on a Fedora core 3 run
server. I think I have proceeded in the right way since I have installed
horde and teste it, the only problem is that I have been unable to install
Auth_SASL

http://85.31.144.205/horde/test.php
http://85.31.144.205/horde/imp/test.php

I am failing to get into the imp component as I type
http://85.31.144.205/horde/imp on the browser and press enter I obtain the
following address on the browser:
http://85.31.144.205/horde/login.php?url=%2Fhorde%2Fimp%2Findex.php&nosidebar=1and
find myself again at the horde login window.

Is there a reason for this?

Bye
