[igniens]

Please finaly add to wordpress feature to share users login sessions and tables with separate permissions between separate installs without editing core

This is what a Multisite Network install is for. See ​https://codex.wordpress.org/Create_A_Network or ​http://www.wpbeginner.com/wp-tutorials/how-to-install-and-setup-wordpress-multisite-network/

Note that you can also use the custom user table functionality in WordPress to share the users and usermeta tables between installations, but this feature has very little documentation.

The CUSTOM_USER_TABLE and CUSTOM_USER_META_TABLE are the constants you should take a look at.

Looks like there is some reference here to 'CUSTOM_USER_TABLE' and 'CUSTOM_USER_META_TABLE'.

I honestly never knew that was an option in core.
