Ephemeral user record was created on some invalid authentication attempts

When attempting to authenticate using API token, an ephemeral user record was created to validate the token in case an external security realm was used, and the user record in Jenkins not previously saved, as legacy API tokens could exist without a persisted user record. This behavior could be...

"Remember me" cookie was evaluated even if that feature is disabled

The "Remember me" feature can be disabled in the Jenkins security configuration. This did not disable the processing of previously set "Remember me" cookies, so they still allowed users to be logged in. "Remember me" cookies are no longer evaluated when the corresponding feature is disabled...
