Is there a way to make Zend_Auth to accept case-insensetive identities(i.e. usernames)? Zend_Auth seems to provide a way to add special treatment to a credential field, but not to identity field.
PS: I am using Zend_Auth_Adapter_DbTable that points to Postgres table.
Something like this should work:
$authAdapter = new Zend_Auth_Adapter_DbTable(
$dbAdapter,
'usertable',
new Zend_Db_Expr('LOWER(username)'),
'password'
);
$authAdapter
->setIdentity(strtolower($this->_getParam('username'))
->setCredential($this->_getParam('password'));
And be sure to use one of the *_ci collations in your database for username field (ci = case-insensitive). Hope it helps
