New install - on SLES 9, Nagios version 2.0rc2

I have followed all the instructions from the documentation. When I go to web browser, I get:

-----------------
Forbidden
You don't have permission to access /nagios/ on this server
-----------------

from /var/log/httpd/error_log:

[Wed Jan 25 15:42:15 2006] [notice] Apache/1.3.29 (Linux/SUSE) configured -- resuming normal operations

--------------------------------

A few things stick out at me. Why do I not have the .cfg files in the /usr/local/nagios/etc directory? i.e cgi.cfg, nagios.cfg. I only have all the samples i.e. cfg.cgi-sample, etc.

Here's the aliases from /etc/httpd/httpd.conf

ScriptAlias /nagios/cgi-bin "/usr/local/nagios/sbin"

<Directory "/usr/local/nagios/sbin">
# SSLRequireSSL
Options ExecCGI
AllowOverride AuthConfig
Order allow,deny
Allow from all
# Order deny,allow
# Deny from all
# Allow from 127.0.0.1
AuthName "Nagios Access"
AuthType Basic
AuthUserFile /usr/local/nagios/etc/htpasswd.users
Require valid-user
</Directory>

Alias /nagios/ "/usr/local/nagios/share"

<Directory "/usr/local/nagios/share">
# SSLRequireSSL
Options None
AllowOverride AuthConfig
Order allow,deny
Allow from all
# Order deny,allow
# Deny from all
# Allow from 127.0.0.1
AuthName "Nagios Access"
AuthType Basic
AuthUserFile /usr/local/nagios/etc/htpasswd.users
Require valid-user
</Directory>

I don't know what else to look at! thanks
