Hi There,
I have just used a tool and instructions to create multiple databases for my Wordpress multisite. It was easy to do with the exception of one thing, adding a user for each database. I want the same user for each data base but don't want to have to go through and add the user to each individual database (256). Is there a way I can add one user to all the data bases.
My host is JustHost
I created the databases using MyPHP from my Cpanel.
To add a user to each db manually I go into MySql

you have 256 identical databases? whoa!

you must've created them one by one, yes?

well, you'll have to add your user one by one, too

According to release notes of release 5.5.7 (14 October 2010), LDAP authentication will be permitted. MySQL :: MySQL 5.5 Reference Manual :: D.1.2 Changes in MySQL 5.5.7 (14 October 2010)

No I didn't create them one by one. I used this info and tool
Multi-DB - Allows you to scale your standard Multisite install to allow for millions of blogs... also will vastly improve the performance of your site! - WPMU DEV

The idea is to let you have 16, 256 or 4096 databases so you can have millions of blogs such as edulblogs.

It doesn't set up the user and password for each db though

I'm looking at your link it-iss.com, thanks
