两个表的Zend_Auth_Adapter_DbTable？

Usually, you keep username and password fields in one table (for example Users). In this case it is easy to use Zend_Auth_Adapter_DbTable. However, what if I have password in a separate Passwords table. How do you uses Zend_Auth_Adapter_DbTable to have identityColumn in a one table (Users) and credentialColumn in other table (Passwords)?

Thanks.

I would recommend creating a table view from Users and Passwords tables. Than you would specify the view as tableName for Zend_Auth_Adapter_DbTable.
