I can't figure this one out. I want to have a single login for all users for multiple WP installs on the same domain.
I've got a site that has a wiki-type knowledgebase that uses a separate install of WordPress, but the same database. Here is how it looks:
Both use the same database with different prefixes (wp_ and wiki_). The main site (http://mysite.com/) is where all the users will be registered. I want it to be that when they login, they are logged in both for the main site and for the knowledgebase. I know it has something to do with setting cookies, but I don't know how to do it.
Any help would be greatly appreciated! I can give more info if needed.

This plugin would help you
Though the same username-password should be present in both installations.
If you have a lot of users registering, you can add a register_form hook (in the first site) to register the same username and password pair in the second installation.

Ahh... Ivaylo's solution definitely deserves the prize money.... much cleaner approach
Ivaylo Draganov answers:
you should be able to accomplish that without a plugin, simply by setting a few things in your <em>wp-config.php</em>. Try adding this to the file:
define('COOKIEPATH', '/' );

I assume that you are using a shared users and usermeta table for both installations. E.g. you have this in your <em>wp-config.php</em> for the wiki-site:
// shared users
