 * hello
    I use a plugin ([http://wordpress.org/extend/plugins/shibboleth/](http://wordpress.org/extend/plugins/shibboleth/))
   for SSO/federated authentication on my multisite WP . login with the plugin (
   shibboleth) works fine on the main site (wp.domain.fr), but if I try to login
   from a “child” site (child.wp.domain.fr/wp-login.php), the wp-login.php doesn’t
   show the shibboleth plugin login options => below the traditional username + 
   password form, there should be a link to “login with shibbolet” that fires up
   shibboleth SSO process.
 * I noticed from the source code (wp-login.php) the line that “creates” the link
   to shibboleth SSO auth
 * <?php do_action(‘login_form’); ?>
 * That line (#598 just after <input type=”password”…) isn’t in a “if” statement,
   so I don’t understand why calling it from wp.domain.fr/wp-login.php has different
   result from calling it from child.wp.domain.fr/wp-login.php !?
 * how can I debug that ? where is that ‘login_form’ hook ?
 * thanks .
