In past I set up Metabase to use LDAP authentication, but recently LDAP auth stopped working (address changed), so I wanted to use my superuser login to reconfigure the settings. But strangely it can't work, although such a user account was created during the initial setup (so it was a local account). Also, when I query Metabase DB, it shows ldap_auth = 0, but still it verifies PW against LDAP. This is a problem when LDAP is not available...
The LDAP server issue has been resolved in the meantime, so I was able to create another local superuser. But I'm still wondering why the original account verifies PW against LDAP ?
