Yes dgilmour ,
I can confirm that it is /path/to/wordpress/ you missed the forward slash at the end , and wordpress is in my /var/www/path/to/wordpress/ , but in the network setup it tells to give RewriteBase as above , so i have the same . and i think wordpress will map it to /var/www/ . or should i give relative path. like path/to/wordpress/

Hello Ipstenu ,
I am having a problem for wordpress multisite , I have just installed a new wordpress 3.2 on my server which runs Ubuntu , and did exactly what is specified in the Network Setup part
Using
1. define('WP_ALLOW_MULTISITE',true);
Then setting up network .
2.

define( 'MULTISITE', true );
define( 'SUBDOMAIN_INSTALL', false );
$base = '/path/to/wordpress/';
define( 'DOMAIN_CURRENT_SITE', 'mydomain.com' );
define( 'PATH_CURRENT_SITE', '/path/to/wordpress/' );
define( 'SITE_ID_CURRENT_SITE', 1 );
define( 'BLOG_ID_CURRENT_SITE', 1 );

3.Created blogs.dir
Created .htaccess file in /path/to/wordpress/ with following contents
4.

# BEGIN WordPress
RewriteEngine On
RewriteBase /path/to/wordpress/
RewriteRule ^index\.php$ - [L]

# uploaded files
RewriteRule ^([_0-9a-zA-Z-]+/)?files/(.+) wp-includes/ms-files.php?file=$2 [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule  ^[_0-9a-zA-Z-]+/(wp-(content|admin|includes).*) $1 [L]
RewriteRule  ^[_0-9a-zA-Z-]+/(.*\.php)$ $1 [L]
RewriteRule . index.php [L]
# END WordPress

After this when i create a site it gives 404 not found error .
