I don't believe there's a module, but you could do a custom one.
- Create a new table with the old user hashes and the new Drupal UID for reference. - When converting the users, the old hash is stored as the actual password in Drupal (letting Drupal md5() it). - Using form_alter add a validation before user_login_authenticate_validate. In this new step check if the password() of the user submitted password matches a record in the database.
If it matches: change $form_state['values']['pass'] to the old password hash and let Drupal do the check from the user table
If no match: Do nothing. If this is a user that was created in Drupal, or an old user that changed their password in Drupal, Drupal will go ahead and validate it using the normal MD5().
Using this method you won't have to do any core hacks. I did something similar on converting a WP site to Drupal, where WP stores the passwords with a salted MD5().

why not export your user data from your old app, import to drupal (decrypt the mysql password, hash with md5) then you dont have to mess about hacking core.

I have an old website/DB that I would like to migrate into Drupal.
At present, it has a user/password setup that encodes the passwords in MySQL using the native MySQL password() function.
Ideally, I’d like to take those users and replace them with Drupal users, in a seamless way and without having to re-set user passwords, such that users can log into the new Drupal website without having to change or re-set their passwords.
Clearly this is difficult as Drupal stores passwords as md5 encoded strings, whereas my passwords are encoded by password().
I notice that the user.module file includes several calls to md5. If I changed all of these to a function which mimics the MySQL password() function, would that enable me to migrate my users into Drupal, allowing them to log into Drupal with their existing passwords?
If that wouldn’t work, suggestions are welcome!
Thanks Mick
