Products.PluggableAuthService 1.5.3

ZODBUserManager plugin: allow unicode arguments to ‘enumerateUsers’. (https://bugs.launchpad.net/zope-pas/+bug/189627)

plugins/ZODBRoleManager: added logging in case searchPrincipial() returning more than one result (which might happen in case of having duplicate id within difference user sources)

Packaging error: the 1.5.2 distribution was made from an ‘svn export’, and thus was missing package data files.

DomainAuthHelper plugin: fix glitch for plugins which have never configured any “default” policy: ‘authenticateCredentials’ and ‘getRolesForPrincipal’ would raise ValueError. (http://www.zope.org/Collectors/PAS/59)

PluggableAuthService._verifyUser: changed to use exact_match to the enumerator, otherwise a user with login ‘foobar’ might get returned by _verifyUser for a query for login=’foo’ because the enumerator happened to return ‘foobar’ first in the results.

Add a test for manage_zmi_logout and replace a call to isImplementedBy with providedBy. (http://www.zope.org/Collectors/PAS/58)

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.

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.

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.

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)

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.

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)

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

No changes from version 1.3-beta

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

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)

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)

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.

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.

Repaired a missing ‘nocall:’ in the Interfaces activation form.

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)

Simplified detection of the product directory using ‘package_home’.

Set a default value for the ‘login’ attribute of a PAS, to avoid UnboundLocalError.

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.

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.

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.

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

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.
