[horde] Cant configure Horde !

[Andy]

Hello together,

I installed Horde Webmail-Edition 1.0.3.

Apache 2.2.3,  php 5.2.0

http://Domain/test.php works unproblematic and is ok. Session Counter works.

I followed the steps:

http://www.horde.org/horde/docs/?f=INSTALL.html#installing-from-release-tarballs
Chapter 4.1 and Chapter 5.1, 5.2, 5.3, 5.4

But if i go to Step 5.5 (i think i have to try http://Domain ?) i get
the message:

Firefox: The page isn't redirecting properly -> So i cant finish Step 5.5


If i got to http://Domain/imp i get the Login Screen, but cant login.

Could you help me , please ? Thanks a lot.

Andy
