In this article, we will see how to fix Harbor Auth Mode which sometimes shows in disabled mode. This is a very common scenario with all those users who has been using Harbor in default Database Auth Mode. The problem comes when you need to change the Authentication mode to anything but Database mode. Currently harbor supports four types of Authentication mode - Database, LDAP, UAA and OIDC. More about Auth Mode on official website.

After fresh installation, by default Harbor will have one user called admin and it uses Database Auth Mode to authenticate the user. Once you logged in as admin user, you will get an option to create new users. The moment you create a new user the Auth Mode will get disabled. Let's understand more about this problem using below example. But before that let's understand the different Auth Mode.
