DiluxOne Multisite User Sync

Out of the box, a WordPress Multisite network keeps its users and its sites apart: a new user joins no site, a new site starts with nobody but its administrator, and a role changed on one site stays there. DiluxOne Multisite User Sync closes that gap from Network Admin.

Formerly WPM User Sync: same plugin, same settings, a new name in the DiluxOne family.

Three automatic triggers, each one on or off

• New user: a user added to the network (by a super admin, by registration, or by another plugin) joins every site, with each site’s default role.
• New site: a new site gets every user of the network, with the new site’s own default role.
• Role change: a role changed on one site is copied to the other sites the user already belongs to, where that role exists. Administrator is never copied.

Two manual actions

• Sync from scratch: every user to every site, or only to the sites you tick. Existing memberships are never changed.
• Add back people who were removed, only if you tick the box: someone an administrator removed from a site stays off it otherwise, whatever the triggers say.

Safe by default

• Super admins are never added as members (they reach every site already), and archived, spam and deleted sites are left alone.
• Only super admins see the plugin. A site’s own administrator cannot pull the network’s users into their site.
• Big networks: a sync too large for one request runs in the background through WP-Cron, in batches, with its progress on the Network Sync Actions screen.
• Users are never duplicated: one account, added to more sites. Uninstalling removes the plugin’s settings and keeps every membership.

Works on any WordPress Multisite host.

For developers

Filters: wpmus_excluded_site_ids (sites the sync never writes to), wpmus_should_sync_user (skip one user on one site), wpmus_replicate_role (which roles the role trigger copies), wpmus_sync_inline_limit, wpmus_sync_batch_size and wpmus_sync_time_limit (how big syncs are split).
