Okay so answering myself:
- I created that bug because the first time I incorrectly mapped some fields (username was mapped on CN and not UID)
- So it re-created the user differently but had a collision with the UID
- I had to
delete from users where id="OLD DUPLICATE UUIDs"
- And then, it worked
Note: when you remove a user, it stays in the DB with
deleted
value to1
, but this prevented to login. I don’t know if I did right, but now it works correctly after manual removal from the DB!
