ZF-10232: Zend_OpenId_Provider encrypts password to md5 no matter what

Description

I am trying to make my existing website and user base into an OpenId provider. The code for Zend_OpenId_Provider->login() uses md5, however my existing user base does not support MD5. Shouldn't it be a setting or option to use md5, another encryption, or none?

Comments

Actually the issue is more complex than I thought.

The code is if (!$this->_storage->checkUser($id, md5($id.$password)))

Why $id.$password?
