Please it would be great to have auth_hook function during login. This function, if defined in conf/zabbix.conf.php, would mangle username and assign groups. We could use it in conjunction with ldap auth. But can be used for any kind of (even external HTTP ) auth to do some username and groups mapping. (like shiboleth)

Example:

/**

• $user - username given by user
• $pass - pass given by user
• return Array ("username" => "student", "groups" => Array ("Admins","Local Admins") );
  */
  function auth_hook($user,$pass) {
  ... connect to ldap using user and pass
  ... optionaly change username (all students will have one zabbix account "student")
  ... optionaly assign groups (from ldap groups)
  }
