PluggableAuthService changelog

PluggableAuthService 1.2-beta (2006/02/25)

New Features

  • Added suppport for exporting / importing a PAS and its content via the GenericSetup file export framework.
  • Made ZODBRoleManager plugin check grants to the principal's groups, as well as those made to the principal directly.
  • Added two new interfaces, IChallengeProtocolChooser and IRequestTypeSniffer. Those are used to select the authorization protocol or challenger protocol to be used for challenging according to the incoming request type.

Bugs Fixed

  • Repaired warings appearing in Zope 2.8.5 due to a couple typos in security declarations.
  • Repaired DeprecationWarnings due to use of Zope2 interface verification.
  • Repaired unit test breakage (unittest.TestCase instances have failUnless/failIf, rather than assertTrue/assertFalse).
  • Fixed a couple more places where Zope 2-style ``__implements__`` were being used to standardize on using ``classImplements``.
  • Fixed fallback implementations of ``providedBy`` and ``implementedBy`` to always return a tuple.
  • Make sure challenge doesn't break if existing instances of the PluginRegistry don't yet have ``IChallengeProtocolChooser`` as a registered interface. (Would be nice to have some sort of migration for the PluginRegistry between PAS releases)
  • Don't assume that just because zope.interface can be imported that Five is present.

PluggableAuthService 1.1b2 (2005/07/14)

Bugs Fixed

  • Repaired a missing nocall: in the Interfaces activation form.

PluggableAuthService 1.1b1 (2005/07/06)

New Features

  • PAS-level id mangling is no more. All (optional) mangling is now done on a per-plugin basis.
  • Interfaces used by PAS are now usable in both Zope 2.7 and 2.8 (Five compatible)

PluggableAuthService 1.0.5 (2005/01/31)

Bugs Fixed

  • Simplified detection of the product directory using package_home.
  • Set a default value for the login attribute of a PAS, to avoid UnboundLocalError.

PluggableAuthService 1.0.4 (2005/01/27)

Features Added

  • Made Extensions a package, to allow importing its scripts as modules.
  • Declared new IPluggableAuthService interface, describing additional PAS-specific API.
  • Exposed PAS' resetCredentials and updateCredentials as public methods.
  • Monkey-patch ZMI's logout to invoke PAS' resetCredentials, if present.
  • CookieAuth plugin now encodes and decodes cookies in the same format as CookieCrumbler to provide compatibility between sites running PAS and CC.
  • Add a publicly callable "logout" method on the PluggableAuthService instance that will call resetCredentials on all activated ICredentialsRest plugins, thus effecting a logout.
  • Enabled the usage of the CookieAuthHelper login screen functionality without actually using the CookieAuthHelper to maintain the credentials store in its own auth cookie by ensuring that only active updateCredentials plugins are informed about a successful login so they can store the credentials.
  • Added a _getPAS method to the BasePlugin base class to be used as the canonical way of getting at the PAS instance from within plugins.
  • Group and user plugins can now specify their own title for a principal entry (PAS will not compute one if they do).
  • PAS and/or plugins can now take advantage of caching using the Zope ZCacheable framework with RAM Cache Managers. See doc/caching.stx for the details.

Bugs Fixed

  • Make getUserById pass the login to _findUser, so that the returned user object can answer getUserName sanely.
  • Harden logout against missing HTTP_REFERRER.
  • Avoid triggering "Emergency user cannot own" when adding a CookieAuthHelper plugin as that user.
  • Detect and prevent recursive redirecting in the CookieAuthHelper if the login_form cannot be reached by the Anonymous User.
  • Made logging when swallowing exceptions much less noisy (they don't necessarily require attention).
  • Clarified interface of IAuthenticationPlugin, which should return None rather than raising an exception if asked to authenticate an unknown principal; adjusted ZODBUserManager accordingly.
  • Don't log an error in zodb_user_plugin's authenticateCredentials if we don't have a record for a particular username, just return None.
  • If an IAuthenticationPlugin returns None instead of a tuple from authenticateCredentials, don't log a tuple-unpack error in PAS itself.

PluggableAuthService 1.0.3 (2004/10/16)

Bugs Fixed

  • Implemented support for issuing challenges via IChallengePlugins.
    • three challenge styles in particular:
      • HTTP Basic Auth
      • CookieCrumbler-like redirection
      • Inline authentication form
  • Made unit tests pass when run with cAccessControl.
  • plugins/ZODBRoleManager.py: don't claim authority for Authenticated or Anonymous roles, which are managed by PAS.
  • plugins/ZODBRoleManager.py: don't freak out if a previously assigned principal goes away.
  • plugins/ZODBGroupManager.py: don't freek out if a previously assigned principal goes away.
  • plugins/ZODBUserManager.py: plugin now uses AuthEncoding for its password encryption so that we can more easily support migrating existing UserFolders. Since PAS has been out for a while, though, we still will authenticate against old credentials
  • Repaired arrow images in two-list ZMI views.
  • searchPrincipals will work for exact matches when a plugin supports both enumerateUsers and enumerateGroups.
  • Authenticated Role is now added dynamically by the PluggableAuthService, not by any role manager
  • Added WARNING-level logs with tracebacks for all swallowed plugin exceptions, so that you notice that there is something wrong with the plugins.
  • All authenticateCredentials() returned a single None when they could not authenticate, although all calls expected a tuple.
  • The user id in extract user now calls _verifyUser to get the ID mangled by the enumeration plugin, instead of mangling it with the authentication ID, thereby allowing the authentication and enumeration plugins to be different plugins.

PluggableAuthService 1.0.2 (2004/07/15)

Bugs Fixed

  • ZODBRoleManager and ZODBGroupManager needed the "two_lists" view, and associated images, which migrated to the PluginRegsitry product when they split; restored them.

PluggableAuthService 1.0.1 (2004/05/18)

Bugs Fixed

  • CookieAuth plugin didn't successfully set cookies (first, because of a NameError, then, due to a glitch with long lines).
  • Missing ZPL in most modules.

PluggableAuthService 1.0 (2004/04/29)

  • Initial release
