Drupal 7 unset drupal_set_message

Question

In the contributed module (ldap_sso.module) a custom drupal_set_message is being declared.

drupal_set_message(theme('ldap_authentication_message_not_authenticated',
  array('message' =>
  t('You were not authenticated by the server.
  You may log in with your credentials below.')
  )
  ), 'error');

How can i override this message or possible unset it via my custom module so it doesn't get called at all when LDAP SSO authentication fails?

Could this be accomplished in settings.php? $conf['locale_custom_strings_en']['You were not authenticated by the server.You may log in with your credentials below.'] = 'Error removed by admin'; — Emir Memic

If you look at the code of drupal_set_message() at https://api.drupal.org/api/drupal/includes%21bootstrap.inc/function/drupal_set_message/7, you will notice that a message gets set only if the $message parameter is not null. So if we somehow set the $message parameter to be NULL, then no message will be set.

Fortunately since the LDAP module is using a theme function, this is easy. Define a theme function in the template.php file of the theme that you are using. Suppose you are using a theme called "mytheme". Then open the template.php file in that folder and add the following code:

/**
 * Implements theme_ldap_authentication_message_not_authenticated().
 */
function mytheme_ldap_authentication_message_not_authenticated(&$vars) {
  return NULL;
}

Clear the cache. Now theme('ldap_authentication_message_not_authenticated', …) will call the theme function that you have defined rather than the one defined by the LDAP module. Since your theme functions returns NULL, message will not be set.
