CiviCRM Community Forums (archive)

We have set up a civicrm multisite, whereby multiple Drupal installations are operating off the same multi-org civicrm installation.

The desired behaviour we are after is that if a user who has an account on one Drupal site subsequently signs up on another one of these Drupal sites (with the same email address), that their new Drupal account will be UF matched to their existing civicrm contact record that had been previously been created for them.

The document here suggests this is the default behaviour ("The default behavior for this case is to map the drupal account having same email address for N sites with same/one civicrm contact") and that if we wanted a new civicrm contact record to be created for each Drupal domain we would have to set the CIVICRM_UNIQ_EMAIL_PER_SITE flag.

We don't have that flag set, and yet for each user that exists on a previous drupal site and has an associated civicrm contact, when they create a new account on another Drupal site (with the same email address) we are seeing a new civicrm contact record created for them.

Are we missing some additional configuration or have we misconfigured this somewhere?

I think in order to make the match you need to include enough information for your de-dupe rule in the profile on user create page.
