Original GitHub issue: https://github.com/modoboa/modoboa/issues/2997

I found a typo in 2.1.0 upgrade instructions. The part saying

You need to add 'modoboa_imap_migration.auth_backends.IMAPBackend', at the end of AUTHENTICATION_BACKENDS:

AUTHENTICATION_BACKENDS = (
   'django.contrib.auth.backends.ModelBackend',
   'modoboa_imap_migration.auth_backends.IMAPBackend',
)

should have modoboa.imap_migration instead of modoboa_imap_migration.

If not, an internal error is triggered upon logging:

ModuleNotFoundError at /accounts/login/

No module named 'modoboa_imap_migration'

FYI, following upgrade instructions I get this when renaming app (new venv after python system upgrade to 3.11):

(env) $ python manage.py rename_app modoboa_dmarc dmarc
Renaming modoboa_dmarc to dmarc, please wait...
Nothing to rename. Exiting.
(env) $ python manage.py rename_app modoboa_imap_migration imap_migration
Renaming modoboa_imap_migration to imap_migration, please wait...
Nothing to rename. Exiting.

Thanks for the report. As for the message, it is normal if you weren't using imap_migration or dmarc extension before.
