Now that a default plug-in has been configured, you must override the authentication method for each user account that requires a non-default method. (Users whose authentication matches the default method do not require any overrides.) For details on settings on the user account screen, see Creating or Editing Users.
The example below presumes that your default authentication method is not LDAP, but some individual users do need to authenticate through LDAP. The steps described are similar no matter which method you are using to override.
Example: User Record - General Page
