Events for admin user login/logut in magento?

Question

Is there any events for admin user login and logout in magento?

I found some events for customer login but not for Admin user login

<events>
         <customer_login>
           <observers>
              <scommerce_customer_login><!--User Defined Unique Name-->
                 <class>scommerce_login/observer</class>
                 <method>checkLoginStatus</method>             
              </scommerce_customer_login>
           </observers>
         </customer_login>
      </events>

For how to get the admin users login events?

Answer 1

Login:

There are one event exit in magento which fire whenever admin user successfully logged in and can get user details from it parameter:

event name: admin_session_user_login_success

See at class: Mage_Admin_Model_Session

  Mage::dispatchEvent('admin_session_user_login_success', array('user' => $user));

Getting loggin user details: $observer->getEvent()->getUser();

Also fire event admin_session_user_login_failed when admin user goes to fail to login

   Mage::dispatchEvent('admin_session_user_login_failed',
        array('user_name' => $username, 'exception' => $e));

Logout:

For Logout cannot find any event. In this can use controller predispatch & Post dispatch event .

As magento doing logout from Mage_Adminhtml_IndexController at logoutAction then use any one of below events

• controller_action_postdispatch_admin_index_logout
• controller_postdispatch_admin_index_logout

Event: controller_postdispatch_admin_index_logout is better for this case.

Answer 3

In addition if you need an event before the admin login (for example to restrict login even with a correct credentials) - you can use this

• admin_user_authenticate_before

Here is some example code resurrected from this dead link (archive.org) (untested):

<frontend>
   <events>
<!-- Add Observers for customer on frontend
      customer_login
      customer_logout
 -->
      <customer_login>
          <observers>
             <xxx_Various_Model_Observer>
                <type>singleton</type>
                <class>xxx_Various_Model_Observer</class>
                <method>Observecustomerlogin</method>
             </xxx_Various_Model_Observer>
         </observers>
      </customer_login>
      <customer_logout>
          <observers>
             <xxx_Various_Model_Observer>
                <type>singleton</type>
                <class>xxx_Various_Model_Observer</class>

</frontend>
      
<adminhtml>
   <events>
