Two blogs working from one user database

A way to do this that works is:

You use the same database for both blogs. The 2nd blog uses a different tablename prefix than the first one. The setting for prefix is in each blog’s wp-config.php file.

Both are separate WordPress installations, using their own WordPress software installations and their own themes.

There is no connection between the two sites other than their separate database tables are in the same database.

The reason for doing it this way is you add code to the wp-config.php files telling the installations to use the users table from the first site on the second site.

Share users between two blogs
Put them both in the same database with different prefixes. Then choose one of them to be the master user table. Then do this in both wp-config.php files:

define(CUSTOM_USER_TABLE,’wp_users’);
define(CUSTOM_USER_META_TABLE,’wp_usermeta’);

Replace the wp_ with the prefix you want.

In other words, you designate the user table from ONE installation as the master user table which will be used by the other installations instead of their own user table. This PHP code must go in the wp-config.php file in all the installations that you want sharing a single user table. You can have more than two installations set up the same way. Their tables must all be in a single database however.

I appreciate your taking the time stvwlf to post this, but when I add this code to my wp-config I get “Cheatin’ uh?” and am not able to access wp-admin/ in the newly-deployed WordPress site.
