Auth source LDAP parameters being filled incorrectly
if you go to the page of LDAP auth source configuration, the username/password fields are automatically pre-filled with current credentials.
which is wrong, because they are optional.
if you firstly define LDAP auth source (without user/pass).
then go again to edit the settings and click save (without clearing the username/password fields)
and then it fucks up the configuration because it saves my credentials for LDAP connection.
