# Authentication and permissions

Date: | November 03, 2011

fine grained authentication and authorization is not yet included as part of the Camelot framework.

what is included is the function :

camelot.model.authentication.getCurrentAuthentication()

which returns an entity of type

camelot.model.authentication.UsernameAuthenticationMechanism

where the username is the username of the currently logged in user (because on most desktop apps, you don’t want a separate login process for your app, but rely on that of the OS).

this function can then be used if you build the Admin classes for your application :

> - set the editable field attribute to a function that only returns Thrue when the current authentication requires editing of fields
> - in the ApplicationAdmin.get_sections method, to hide/show sections depending on the logged in user
> - in the EntityAdmin subclasses, in the get_field_attributes method, to set fields to editable=False/True depending on the logged in user
