Introduction:
Artifactory allows setting a user locking policy to lock users after exceeding the maximum failed login attempts configured. This policy can be enabled or disabled via the UI by navigating to Administration → User Management → Settings:
The policy can be also edited via REST API using the Configure User Lock Policy call.
Resolution:
To unlock a locked user, a user with Administer Platform permission can perform one of the following:
It is also possible to unlock all of the locked users as opposed to a specific user, via the UI by navigating to Administration → User Management → Settings and selecting “Unlock All Users”, or, via REST API using the Unlock All Locked Out Users call.
What if none of the admin users have access to Artifactory?
In this scenario, we can either recreate an existing administrator user or bootstrap a new admin user in order to obtain administrator access to Artifactory and unlock other users or change the user locking policy. This can be achieved by following the steps listed in this documentation section of Recreating the Default Admin User.
