403 Forbidden
I've done several Drupal installs before, and have never run into this problem until now. I've got drupal installed in /var/www/drupal. I'm doing a fresh install on a development box running Debian Lenny.
I've got the following directives configured in apache:
DocumentRoot /var/www/drupal/
<Directory />
Options FollowSymLinks
AllowOverride None
</Directory>
<Directory /var/www/drupal/>
RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?q=$1 [L,QSA]
RewriteCond %{HTTP_HOST} ^www\.mydomain\.com/?$ [NC]
RewriteRule ^(.*)$ mydomain.com$1 [L,R=301]
Options Indexes FollowSymLinks MultiViews
AllowOverride all
Order allow,deny
allow from all
</Directory>When I opened a browser and went to www.mydomain.com/install.php, I got the following 403 error.
"You don't have permission to access /install.php on this server.
"Apache/2.2.9 (Debian) PHP/5.2.6-1+lenny3 with Suhosin-Patch mod_python/3.3.1 Python/2.5.2 mod_ssl/2.2.9 OpenSSL/0.9.8g mod_perl/2.0.4 Perl/v5.10.0 Server at www.mydomain.com Port 80"
I've checked the file permissions on install.php and they're set to 644 and the permissions on the directory are set to 755.
I commented out the lines from the .htaccess file that restrict access to install.php.
I triple checked my apache configuration to ensure there was nothing in it that would prevent access to this file. I can't find anything. I've installed Drupal on several different Debian machines in the past and never encountered this problem. In fact, previous installations were pretty much text book. I don't think I did anything differently this time. I checked the documentation to ensure I'd covered all of the bases and it appears I have. I can't think of anything else that would be causing this error.
Anyone have any ideas?

What did you have restricting
What did you have restricting access to install.php? When you removed them did you restart apache?
