  PluggableAuthService 1.6 (unreleased)

    Features Added

    Bugs Fixed
  

  PluggableAuthService 1.5 (06/17/2007)

    Features Added

      - Add support for property plugins returning an IPropertySheet
        to PropertiedUser. Added addPropertysheet to the IPropertiedUser.

      - Added a method to the IRoleAssignerPlugin to remove roles from a
        principal, and an implementation for it on the ZODBRoleManager.
        (http://www.zope.org/Collectors/PAS/57)

      - Added events infrastructure. Enabled new IPrincipalCreatedEvent and
        ICredentialsUpdatedEvent events.

      - Added support for registering plugin types via ZCML.

      - Implemented authentication caching in _extractUserIds.

      - Ported standard user folder tests from the AccessControl test suite.

    Bugs Fixed

      - Passwords with ":" characters would break authentication
        (http://www.zope.org/Collectors/PAS/51)

      - Corrected documented software dependencies

      - Converted to publishable security sensitive methods to only accept
        POST requests to prevent XSS attacks.  See
        http://www.zope.org/Products/Zope/Hotfix-2007-03-20/announcement and
        http://dev.plone.org/plone/ticket/6310

      - Fixed issue in the user search filter where unrecognized keyword
        arguments were ignored resulting in duplicate search entries.
        (http://dev.plone.org/plone/ticket/6300)

      - Made sure the Extensions.upgrade script does not commit full
        transactions but only sets (optimistic) savepoints. Removed bogus
        Zope 2.7 compatibility in the process.
        (http://www.zope.org/Collectors/PAS/55)

      - Made the CookieAuthHelper only use the '__ac_name' field if
        '__ac_password' is also present. This fixes a login problem for
        CMF sites where the login name was remembered between sessions with
        an '__ac_name' cookie.

      - Made the DomainAuthHelper return the remote address, even it the
        remote host is not available (http://www.zope.org/Collectors/PAS/49).

      - Fixed bug in DelegatingMultiPlugin which attempted to validate the
        supplied password directly against the user password - updated to use
        AuthEncoding.pw_validate to handle encoding issues

      - Fixed serious security hole in DelegatingMultiPlugin which allowed
        Authentication if the EmergencyUser login was passed in.  Added
        password validation utilizing AuthEncoding.pw_validate

      - Fixed a set of tests that tested values computed from dictionaries 
        and could break since dictionaries are not guaranteed to have any 
        sort order.

      - Fixed test breakage induced by use of Z3 pagetemplates in Zope
        2.10+.

      - BasePlugin: The listInterfaces method only considered the old-style
        __implements__ machinery when determining interfaces provided by
        a plugin instance.

      - ZODBUserManager: Already encrypted passwords were encrypted again in
        addUser and updateUserPassword.
        (http://www.zope.org/Collectors/Zope/1926)

      - Made sure the emergency user via HTTP basic auth always wins, no matter
        how borken the plugin landscape.

    Other

      - cleaned up code in CookieAuthHelper which allowed the form to override
        login/password if a cookie had already been set.

      - Removed some BBB code for Zope versions < 2.8, which is not needed 
        since we require Zope > 2.8.5 nowadays.

  PluggableAuthService 1.4 (2006/08/28)

    Bugs Fixed

      - Extended the DomainAuthHelper to function as its own extraction
        plugin, to allow for the case that another extractor is registered,
        but does not return any credentials.
        (http://www.zope.org/Collectors/PAS/46)

      - Re-worded parts of the README so they don't point to specific or 
        non-existing files (http://www.zope.org/Collectors/PAS/6 and
        http://www.zope.org/Collectors/PAS/47)

  PluggableAuthService 1.4-beta (2006/08/07)

    Features Added

      - Created a "Configured PAS" entry in the ZMI add list, which
        allows creating a PAS using base and extension GenericSetup profiles
        registered for IPluggableAuthService.  This entry should eventually
        replace the "stock" PAS entry (assuming that we make GenericSetup
        a "hard" dependency).

      - Added an "empty" GenericSetup profile, which creates a PAS containing
        only a plugin registry and a setup tool.

    Bugs Fixed

      - Repaired the "simple" GenericSetup profile to be useful, rather than
        catastrophic, to apply:  it now creates and registers a set of
        ZODB-based user / group / role plugins, along with a basic auth
        helper.

      - ZODBUserManager: Extend the "notional IZODBUserManager interface"
        with the left-out updateUser facility and a corresponding
        manage_updateUser method for ZMI use. Removed any responsibility
        for updating a user's login from the updateUserPassword and
        manage_updateUserPassword methods. This fixes the breakage
        described in the collector issue below, and makes the ZMI view
        for updating users work in a sane way.
        (http://www.zope.org/Collectors/PAS/42)

      - CookieAuthHelper: If expireCookie was called and extractCredentials
        was hit in the same request, the CookieAuthHelper would throw an
        exception (http://www.zope.org/Collectors/PAS/43)

    Other

      - Added a DEPENDENCIES.txt. (http://www.zope.org/Collectors/PAS/44)

  PluggableAuthService 1.3 (2006/06/09)

    No changes from version 1.3-beta


  PluggableAuthService 1.3-beta (2006/06/03)

    Other

      - Modify CookieAuthHelper to prefer __ac form variables to the cookie
        when extracting credentials.
        (https://dev.plone.org/plone/ticket/5355)


  PluggableAuthService 1.2 (2006/05/14)

    Bugs Fixed

      - Fix manage_zmi_logout which stopped working correctly as soon as the
        PluggableAuthService product code was installed by correcting the
        monkeypatch for it in __init__.py.
        (http://www.zope.org/Collectors/PAS/12)

      - Add missing interface for IPropertiedUser and tests
        (http://www.zope.org/Collectors/PAS/16)

    Other

      - Removed STX links from README.txt which do nothing but return 
        404s when clicked from the README on zope.org.
        (http://www.zope.org/Collectors/PAS/6)

      - Fixing up inconsistent searching in the listAvailablePrincipals
        method of the ZODBRoleManager and ZODBGroupManager plugins. Now both
        constrain searches by ID.
        (http://www.zope.org/Collectors/PAS/11)

      - Convert from using zLOG to using the Python logging module.
        (http://www.zope.org/Collectors/PAS/14)


  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
