Looking for a WordPress plugin to sync userdatabase


Hi guys,

I’m looking for a plugin thats sync the user database of several wordpress installations (no Multiside!).
It’s the same like here on envato. You register on themeforest but you can login in all other platforms with the same account (even auto-login on all platforms).

Is there already a plugin what can do this? Would be awesome!

I can pay for it or i can offer a german translation for your plugins/themes.


Hi thanks for your offer.
Can you also include the IPBoard SSO (Single Sign On) technology?

IPS Connect: http://www.invisionpower.com/support/guides/_/advanced-and-developers/integration/ips-connect-r27

My WordPress Side should be the Master-Side and the IP.Board forum and the sublevel domain should be a slave side.

So someone register on the any side (master or slave) he should be able to login with the same account on every other side and platform (automatically).

If you can do this, how much does it cost?



This does not require a plugin, this can be done on each wordpress installation via the wp-config.php file. Just add the following code, I have this set under define(‘WP_DEBUG’, false); on my setup.

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

wp_users , wp_usermeta being the name of the user database you want to utilize, so change this to whatever yours may be. This is a free and easy solution. This however only appears to allow the login credentials between sites, meaning you would have to log into each site.
