Hi there, running "./manage.py migrate" does not complete when MySQL database is used (independent of InnoDB/MyISAM) and yields the error below. Using SQLite everything is working fine.

Running migrations for django_authopenid: - Migrating forwards to 0005_auto__del_externallogindata.

django_authopenid:0001_initial django_authopenid:0002_make_multiple_openids_possible ! Error found during real run of migration! Aborting.

! Since you have a database that does not support running ! schema-altering statements in transactions, we have had ! to leave it in an interim state between migrations.

! You might be able to recover with: = ALTER TABLE django_authopenid_userassociation DROP COLUMN provider_name CASCADE; [] = ALTER TABLE django_authopenid_userassociation ADD CONSTRAINT django_authopenid_userassociation_user_id_uniq UNIQUE (user_id) []

! The South developers regret this has happened, and would ! like to gently persuade you to consider a slightly ! easier-to-deal-with DBMS. ! NOTE: The error which caused the migration to fail is further up.
