How can i login using email address in zend? - zend-framework

Question

I have the situtation like , Admin should login as User from Admin End. I have user email address which is username for my site.
I am using following code in login page.
...
$users = new Default_Model_DbTable_Users();
$auth = Zend_Auth::getInstance();
$auth = Zend_Auth::getInstance();
$authAdapter = new Zend_Auth_Adapter_DbTable($users->getAdapter(),'customers');
$authAdapter->setIdentityColumn('email')->setCredentialColumn('password');
$authAdapter->setIdentity($username)->setCredential(base64_encode($password));
$authAdapter->getDbSelect()->where('status = 1');
$result = $auth->authenticate($authAdapter);
.....
Now I have to use only email address to login. I can check whether ADMIN do the user login from admin end. Is it possible to login using email address ?. Kindly advice on this

If you would like to allow admin to log in as any user from the admin panel, you don't have to use Zend_Auth::authenticate() to check any credentials against the database. All you really need to do is set up the identity like you do for a normal user login.
From admin you might do something like this:
$user = getUserInfoFromDatabase(); // get the user object used for Zend_Auth identity
$auth = Zend_Auth::getInstance()->getStorage()->write($user);
// redirect admin to user frontend
The only important thing is that whatever you write() to the storage, must be the EXACT same object/data you write to storage from your user login code.
It doesn't matter how the data gets there, as long as it is what your application requires to check identity.
Since your admin has already been authenticated and has permission to access a user account, you don't need to use Zend_Auth::authenticate() to validate the user email/password, you can skip that step and simply assign the identity for the admin directly to the session.
You may need to use separate session namespaces for admin and users if you are not already.
Hope that helps, let me know if I can clarify anything. The part where you set the identity is probably short after $result = $auth->authenticate($authAdapter); in your code, probably inside if ($result == true)
