I’ve just added a new user to my gitlab and he’s unable to authenticate with an ssh token. He’s using his id_rsa.pub token that was generated using
ssh-keygen -t rsa -b 4096 -C "firstname.lastname@example.org"
git config user.email shows the matching email address
RSA auth is enabled in the admin settings
Every time we try to do say a pull or just
ssh -T email@example.com we get asked for git@gitlab’s password
We have another user who is using ssh auth without issues. His key is also RSA
