In migrating user accounts from a non-drupal database, the userid's came over okay, but the clear text passwords were rejected by the drupal database, requirng the user to request a new password by email. Is there a way to have the old passwords be encrypted in such a way so that the old passwords can be accepted? there are about 1000 accounts and likely several accounts' emails have not been updated so some users may not be able to receive new password emails. I have a fresh install so have not attempted to migrate them yet for a second time, so I can follow any steps necessary to make it work. Thanks.
