It's difficult to answer without knowing more about your actual setup. I
don't know anything about the SSLAuth or django_auth_ldap apps, so I don't
know what they're doing internally. However, because they're doing fun
things with Django 1.3 authentication, it's possible they might be bending
some rules, making some model changes via monkey patching, or doing
otherwise unexpected things with auth.
In this case, the error you're getting is caused because the auth.User
model wasn't found in the app cache. This could be because
django.contrib.auth isn't in INSTALLED_APPS, or because one of the apps
you're using is patching the contents of the app cache for some reason.
Sorry I can't be more helpful here - if you can point us at the exact
repositories you're using for SSL auth and auth_ldap, it might be possible
to provide some more assistance.
Yours,
