No can do. I mean, you can't do something like that. You can either give (actually, revoke) that particular user/role permisions to read the table with the passwords, or you could store hashed values to the database. Later is prefered, I'd say. You could use md5() function to create hashes, store those in the database, and when checking for the credentials compare the hases. You'd compare user input flushed trough md5() function with the hash you have in the database. That way you don't know what user passwords are, and you could only set a new password if user forgets his/hers password. You don't need encrypted passwords.
