function user_login_default_validators

Set up a series for validators which check for blocked users, then authenticate against local database, then return an error if authentication fails. Distributed authentication modules are welcome to use hook_form_alter() to change this series in order to authenticate against their user database instead of the local users table. If a distributed authentication module is successful, it should set $form_state['uid'] to a user ID.

We use three validators instead of one since external authentication modules usually only need to alter the second validator.

Return value

array A simple list of validate functions.
