I faced with issue when migrating user passwords. After update i unable to login with my password which is store in mongodb. I have look into mongo to get my password and it equal to stored in not update graylog 1.x but i can to login to old graylog 1.x and not able with the same password on just updated graylog 2.2 and mongo 3.4. Also hash passwords of my user are the same on both updated and not updated instances. I can change my password through admin login, and after change i see it change format in mongo (added bcrypt and salt). I can it do for my login but it is no way for other users who also use graylog. Is there a way smooth migrating users from 1.x graylog to 2.2? Thank you.
Seems graylog haven’t update format stored password in mongodb properly, but i did all things by guidance.
