How to configure different authenticators in Athento?

The different authenticators in Athento are configured at different levels (settings, advanced interface, etc).
In the case of framework level configuration, it is done by defining the AUTHENTICATION_BACKENDS property in the local_settings.py file.

For example, the following configuration allows to have LDAP authenticator and authenticator against database:

AUTHENTICATION_BACKENDS = (
    'ldapase.ldapteams.TeamsLDAPAuthenticationBackend',
    'django.contrib.auth.backends.ModelBackend',
)

The following configuration allows to restrict access only for special users against the database, leaving all other access restricted to authentication against LDAP:

AUTHENTICATION_BACKENDS = (
    'ldapase.ldapteams.TeamsLDAPAuthenticationBackend',
    'users.auths.AdminUserAuthenticationBackend',
)
