Vidispine Authentication

Vidispine can be set as the authentication source for Cantemo using 'portal.vidispine.authentication.VidispineBackend', as an item in AUTHENTICATION_BACKENDS in settings.py. This authentication backend becomes the master. Cantemo users and groups are created and deleted as needed based upon users and groups in the Vidispine system:

AUTHENTICATION_BACKENDS = (
    'portal.vidispine.authentication.VidispineBackend',
    'django.contrib.auth.backends.ModelBackend',
)

You can setup Vidispine to authenticate against other backends such as Active Directory or OpenLDAP. Please consult the Vidispine documentation for this integration.

Authentication Method

Provides authentication from Vidispine to the system.

class portal.vidispine.authentication.VidispineBackend

This backend is required to check whether a user is valid against Vidispine. Then it grabs a list of all the groups a user is in. If the User is not already created in Portal, it is created. The groups that a user is in in Vidispine are added to Portal, and then added to the user.
