The docs indicate that the only thing required for auto-create to work, once it's enabled, is for a successful authentication from another extension, so I would expect that it should be creating accounts for you if they are successfully authenticating against LDAP. Haven't tested in our environment.
As far as adding unsalted passwords, make sure to heed the warning in the docs. Even if you are using the database accounts as "dummies" and they are all authenticating against LDAP, I *believe* that they can still auth against the database with the password in the DB, regardless of LDAP. May be wrong on that, but if that's right, and your DB was compromised, the unsalted hashes are easy to break. There is a code example in the docs about how to salt the hashes in MySQL.
