Group Role sync not mapping users but duplicating users
The group role sync module doesn't seem to work properly anymore. When I create a new user and I log in for the first time, instead of mapping the Drupal user id with the civicrm user id, the module maps the drupal user id to a new user that has everything blank apart from the email.
I checked in the database, and in the table uf_match to confirm and here is (I think) what the module does.
When a user logs in, the checking of the existing user doesn't work anymore, so a new user is created with only the email field and that new user civicrm id is mapped with the drupal id in the uf_match table.
This is causing a lot of problems in our website. I updated to the latest version, 5.17.3 but that didn't fix it either. I noticed this error since version 5.11
