sharing contents between two sites i setup two sites site 1 and site 2 by using drupal multi site functionality.site1 i consider as the master site and site 2 consider as the slave. some contents in both sites have similar content.when updation made in site 1 its reflect in site 2(only similar contents) for this i try to share the DB. while i try to execute following steps i get following error while i see the site pages

"You are not authorized to access this page. "

i follow this steps:

1.create a db prefix like this $db_prefix = "master_" in site 1 and $db_prefix = "slave_" in site 2.


i set the cookie $cookie_domain = 'site2'; in site 1.
Then i add prefix like way in site 1
$db_prefix = array(
node' => 'master_',
'node_access' => 'master_',
'node_counter' => 'master_',
'node_type' => 'master-',
); 


above thing i did site2 also instead of using 'master_' i use 'slave_'
is there any thing missed out in my con fig.any one guide me do this.
thanks......
Multisite isn't really meant for situations where you want to share content.  This is what Domain Access module does.  Essentially, it allows you to have different behaviors for a site with subdomains, but running from the same database.  This is different from multisite, which uses a different database for each site.  I would try starting with that before you go down the road of multisite.
