Authentication for Grok applications

Project description

Sitting on the top the zope.pluggableauth package, dolmen.authentication extends it to add reusable component descriptions and implementations.


dolmen.authentication provides interfaces and components:

>>> import dolmen.authentication
>>> from dolmen.authentication import IAuthenticationInterfaces
>>> from dolmen.authentication import IAuthenticationEvents
>>> from dolmen.authentication import IAuthenticationAPI

>>> IAuthenticationAPI.isOrExtends(IAuthenticationInterfaces)

>>> IAuthenticationAPI.isOrExtends(IAuthenticationEvents)

>>> from zope.interface.verify import verifyObject
>>> verifyObject(IAuthenticationAPI, dolmen.authentication)

Descriptive interfaces

dolmen.authentication provides a set of base interfaces that can be used to normalize an authentication system:

>>> print IAuthenticationInterfaces.__doc__
This interface describes and exposes the meaningful interfaces
of the authentication module.

>>> interfaceDescription(IAuthenticationInterfaces)
IPrincipalFolder: A container specialized in storing principal representations.
IAccountStatus: Abstraction component allowing to check the status of a principal.
IPrincipal: A principal representation, directly inheriting from IPrincipal, but redefining several fields for a user-friendly form display.
IGroup: A logical grouping of principals. This component is an IPrincipal itself.
IPasswordProtected: This interface defines any component protected by a password
IPasswordChecker: Abstraction component in charge of resolving a principal'scredentials.

>>> IAuthenticationInterfaces.providedBy(dolmen.authentication.interfaces)

>>> verifyObject(IAuthenticationInterfaces, dolmen.authentication.interfaces)

Events interfaces and implementations

dolmen.authentication provides a set of basic events that can be used and declined, in order to handle and trace principals’ lifecycles:

>>> print IAuthenticationEvents.__doc__
This interface describes and exposes the meaningful events
descriptions and components of the authentication module.

>>> interfaceDescription(IAuthenticationEvents)
IUserLoggedOutEvent: IObjectEvent extending event : a user has logged out.
IUserLoggedInEvent: IObjectEvent extending event : a user has logged in.
UserLogoutEvent: An IUserLoggedOutEvent implementation.
UserLoginEvent: An IUserLoggedInEvent implementation.

>>> IAuthenticationEvents.providedBy(

>>> verifyObject(IAuthenticationEvents,


0.3 (2012-01-17)

  • Updates on code to fit last changes in the Dolmen/Grok stack.

0.2 (2010-05-29)

  • the LocatablePrincipalInfo adapter now implements _and_ provides the IPrincipalInfo interface. This allows the adapter to be used in the AuthenticatedPrincipalFactory adaptation.

0.1 (2010-03-26)

  • Initial release.
