Enabling trusted authentication

Before embedding CDV Services within client pages, you must first enable trusted authentication on the CDV Server.

Add the following settings to the advanced site settings.
```
INSTALLED_APPS = INSTALLED_APPS + ('trustedauth',)
      
AUTHENTICATION_BACKENDS = (
      'django.contrib.auth.backends.ModelBackend',
      'trustedauth.backends.TrustedAuthBackend'
)
      
TRUSTED_AUTH = {
      'trusted_ips': ['127.0.0.1'],
      'trusted_users': ['tadmin'],
      'timeout': 120,
      'single_use': True,
      'session_expiry': 0,
      'allow_superuser': True
}
```
Settings explanation:

trusted_ips:

A list of trusted IPs. Ticket requests from these IP addresses are validated. You can either specify a list of trusted_ips, a list of trusted_users, or both.

trusted_users:

A list of trusted ticket-granting usernames. You can either specify a list of trusted_users, a list of trusted_ips, or both.

timeout:

The time that the ticket remains valid, in seconds.

single_use:

The ticket can be used only one time.

session_expiry:

The duration time of the user session, in seconds. A setting of 0 ends the user session when the browser closes.

allow_superuser:

Allows authentication of a user with admin privileges using a ticket. Set this to False to disable this feature.
Restart the application to apply the new configuration.
