 * Hello.
 * I’m in the process of updating an ancient multisite installation to 3.9.1. Through
   a number of hacks to the core this installation has a two-tiered user system 
   where there are global users (which work as per normal) and site-specific users(
   which are unique per site but not globally). This behavior is absolutely critical
   and must be preserved, although it is acceptable if the site-specific users have
   to be recreated.
 * Of course the update completely breaks everything. The per-site user management
   works by duplicating half of the regular user management functions and hooking
   into various pluggable functions to decide at login time which functions to call.
   This is extremely brittle but at the time was seen as the only way to have both
   a centralized WordPress installation and per-site users.
 * Now I’d like to know if there is a better way of obtaining all of the following
   in WordPress 3.9:
    – One single installation for all sites – The admin can manage
   all sites without having to log into them separately – Each site can have site-
   specific users that are unique within the site but not across sites

 * Better than Multisite? Not really. I mean, that’s what it does.

 * Multisite adds users to the network, which means they’re ‘subscribers’ of a sort
   to all sites, but only have writing access on sites where they’re specifically
   added to.

 * Unfortunately this makes the user namespace global. My question not about not
   being able to write, it’s about sharing usernames.
 * The sites in this network are completely independent of each other and use the
   User Access Manager plugin to have pages accessible only to logged-in users. 
   The site owners expect to be able to use arbitrary usernames for their users –
   if their blog’s user list has no user called “smith” they expect to be able to
   create one.
 * With regular WordPress users they can only do so if no other blog has a user 
   called “smith”. That is unacceptable; the blog owners expect to have no restrictions
   over what a single-site WordPress installation would give them.
 * If there is no elegant way of doing this in Multisite I’ll just port the code
   over. It’s not pretty (especially in how it still litters the global user table
   with dummy entries) but at least it gets the job done…
