After long research, I finally found a solution the solution was to put allow from all in the svn configuration on httpd.conf:
<Directory /repos>
...
allow from all
...
</Directory>
The svn checkout is working fine now
The above are for apache 2.2
if you use apache 2.4
<Directory /repos>
...
require all granted
...
</Directory>
In 1.7.2 the support for Directory directives is lost as mod_dav_svn will no longer map URLs to the filesystem. Instead be sure to use the Location directive. subversion.apache.org/docs/release-notes/…
If you use apache 2.4 use require all granted instead
