[Web-cyradm] index.php gives "redirecting" error

[Mufit Eribol]

Dear All,

I have been a happy user of web-cyradm for quite a long time. I had 
built it as per Luc's HOWTO on a Fedora Core 3 box.

On a new box running Centos 5.1, I would like to install the same 
components again. I have already installed Postfix, Cyrus-Imap, 
Spamassassin, Amavisd-new etc. The problem is I can't get the index.php 
page of web-cyradm in the browser. Nothing at all. Firefox prints the 
following error:

The page isn't redirecting properly
Firefox has detected that the server is redirecting the request for this 
address in a way that will never complete.
    *   This problem can sometimes be caused by disabling or refusing to 
accept
          cookies.

But, the browser is configured cookies.

Here are some more details:
php-5.1.6-15.el5
httpd-2.2.3-11.el5_1.centos.3
mysql-5.0.22-2.2.el5_1.1
cyrus-imapd-2.3.7-1.1.el5

"cyradm --user cyrus localhost" works fine too. There is no any email 
address configured yet. phpmyadmin works fine.

I can normally publish html files easily. I tried copying web-cyradm 
just in the root of apache (/var/www/html) just to avoid any Alias entry 
in httpd.conf, but i have got the same result.

There must be some problem I overlook.

Best wishes,
Mufit
