Cakephp authentication from two tables

Hi All,

I am using cakephp 2.0, I have two tables called accounts,subaccounts with fields as id,email,password. The table accounts contains the main account of a user and table subaccounts contains the sub account of a user in the accounts table.

I have one login action for both of these accounts and subaccounts. What i planning do is that when a user enter an email and password in the login form then it will check the email id and password in both the accounts and subaccounts table and if any of these table match with the login information then it will go to the home page. Is it possible with the Cakephp using Auth Component ? If anyone knows the solution please help me to sort out.

Thanks in advance
