Need help Apache 403 client denied by server configuration

Hi,

i try to install OTRS but i do not succed because of 403 ERROR ...

i have this problem when i want to access to my intranet page :
http://intranet.toto.com/otrs/installer.pl

I have this error :
Forbidden

You don't have permission to access /otrs/installer.pl on this server.

Additionally, a 403 Forbidden error was encountered while trying to use
an ErrorDocument to handle the request.
Apache/2.0.46 (Red Hat)

and in my Apache log :
client denied by server configuration:
/opt/otrs/bin/cgi-bin/installer.pl

I do not understand, i spent a lot of time on many forum and nothing
is working yet !!!

Can someone help me ???

This is my httpd.conf from apache :
