PlonePAS adapts the PluggableAuthService for use by Plone.
Project description
Overview
This product adapts the “PluggableAuthService”:http://svn.zope.org/PluggableAuthService/ for use by Plone.
Notes
Why doesn’t the title of my group, that I set in the ZODB, show up? The title for a group comes from the properties plugin. The info in the groups plugin isn’t used, except for the name.
The value of the ‘title’ property on the portal_groupdata or portal_memberdata tools themselves (as opposed to the group or member data records within them) will not be used as a default for the title of the group or member. This is to prevent UI confusion if a title is set without realizing the implications. To remove this special case, see ‘plugins.property._getDefaultValues’.
If PAS caching is enabled (see the “Cache” tab) and the cache manager does not have a ‘cleanup’ method (RAMCacheManager has one), then changes to the memberdata schema will not effect users already cached. In this case, restart the server or clear the cache (if possible) for the changes to take effect.
Similarly, changes to the memberdata schema will not propagate to member objects already in use. If you have a memberdata object and change the memberdata properties you must re-construct the member by saying portal_membership.getMemberById again. See ‘tests.test_properties.test_user_properties’ for example.
By default, logout from users signed in under HTTP Basic Auth cannot log out. If you enable the “Credentials Reset” plugin for the HTTP Basic plugin, the logout for cookies will no longer work. However, this is not a problem if you’re not using cookies.
Implementation
In some places, PlonePAS acts as an adaptor to make PAS provide enough of GRUF’s interface to satisfy Plone. All the monkey patches in pas.py, for instance, extend PAS with expected methods.
PlonePAS also modifies Plone to work with PAS by providing partially-new implementations of several tools. In the tools/ directory you can see new tools for groups and members, as well as the utils tool.
It also provides extra capabilities for PAS needed by plone, such as mutable property sheets, local role calculation, creation of group objects, and more.
Changelog
4.0.7 - 2011-05-12
Copy in CleanupTemp from CMFCore as it has been removed from CMFCore 2.3. [elro]
Move import step to be registered in ZCML rather than XML. Remove the non-existent dependency on plonepas-content. [kiorky]
4.0.6 - 2011-02-25
Fix missing and broken security declarations. [davisagli]
4.0.5 - 2011-02-14
Avoid breaking on startup if PIL isn’t present. [davisagli]
Use ‘defaultUser.png’ as the default user portrait, since the .gif version has been deprecated for a long time now. See http://dev.plone.org/plone/changeset/36350 [mj]
4.0.4 - 2011-01-03
Remove plone.openid dependency in setup.py, import errors are already caught in PASInfoView. [elro]
The code to search by id in mutable_properties.enumerateUsers didn’t work at all, an exception was always raised and it was actually a good thing. We tried to implement it in 3.10 and we had strange listing in Plone UI. Then we reverted it in the next version so the behavior was backward compatible with previous versions. If we allow search by id, we can potentially break other part of the code. For example acl_users/portal_role_manager/manage_roles will break because Products.PluggableAuthService.plugins.ZODBRoleManager.listAssignedPrincipals raises MultiplePrincipalError, and maybe it will break somewhere else. Versions 4.0.4 and 3.13 use now the same algorithm. References http://dev.plone.org/plone/ticket/9361 [vincenfretin]
When calling editGroup method, avoid error while trying to remove dynamic ‘AuthenticatedUsers’ group. [thomasdesvenain]
In Plone 4.1+, create a Site Administrators group with the new Site Administrator role. [davisagli]

Fix interface error: doChangeUser takes a user id as parameter, not a login name. [wichert]
4.0.3 - 2010-09-09
Check we have a REQUEST attribute before accessing it in getRolesForPrincipal. [vincentfretin]
Use safe_unicode to correctly find users with non-ascii properties, regardless of the sys.defaultencoding. This fixes http://dev.plone.org/plone/ticket/10898 [mr_savage]
4.0.2 - 2010-08-08
Made last_login_time logic compatible with DateTime 2.12.5. [hannosch]

4.0 - 2010-07-18
Avoid a deprecation warning for the credentialsChanged method. [hannosch]
Fixed problems with missing user cache invalidation. This closes http://dev.plone.org/plone/ticket/10715. [fafhrd, hannosch]
Make VirtualGroup inherit from PropertiedUser so it gets wrapped correctly. Have getGroupsForPrincipal not return the AutoGroup as a member of itself. Closes http://dev.plone.org/plone/ticket/10568. [cah190]
PluggableAuthService expects a list of group ids from getGroups, don’t pass a list of wrapped groups instead. [cah190, esteele]
Added a custom IMembershipTool interface to PlonePAS extending the base one from CMFCore. It adds the getMemberInfo method to the mix. This closes http://dev.plone.org/plone/ticket/10240. [hannosch]
4.0b9 - 2010-06-03
Fixed a test to no longer use removed Large Plone Folder type. [davisagli]
4.0b8 - 2010-05-01
Removed special unauthorized view workaround, after the underlying issue has been fixed in Zope2. [davisagli, hannosch]
4.0b7 - 2010-04-07
Added manage_setMembersFolderById method for ZMI. Fixes http://dev.plone.org/plone/ticket/10400 [daftdog]
4.0b6 - 2010-03-05
Revert incorrect PIL import change. [hannosch]
4.0b5 - 2010-03-03
Install recursive_groups in new sites by default. Make it the last IGroupsPlugin installed. [esteele]
Remove caching of utils.py’s getGroupsForPrincipal method as it was nastily overzealous. [esteele, cah190]
Use sets instead of util.py’s ‘unique’ method. [esteele]
4.0b4 - 2010-02-18
Properly import from PIL 1.1.7 [tom_gross]
Cache getGroupsForPrincipal per principal id per request (when available). [esteele]
4.0b3 - 2010-01-31
Role plugin’s tests no longer subclass (and run all of) ZODBRoleManagerTests as they cannot properly handle the plugin’s expectation of finding a PluginRegistry with IGroupsPlugin [erikrose, esteele]
Revert changes made to ZODBMutablePropertyProvider’s enumerateUsers method which prevented lookup of users by id. Some refactoring. Refs http://dev.plone.org/plone/ticket/9361 [erikrose, esteele]
GroupAwareRoleManager now properly computes the roles of deeply-nested principals. [erikrose, esteele]
Factor up getGroupsForPrincipal call. [erikrose, esteele]
AutoGroup now implements IPropertiesPlugin to return group title and description. [erikrose, esteele]
GroupsTool’s getGroupsForPrincipal and getGroupMembers now return a list made up of groups/members from all responding plugins instead of just the first responder. [erikrose, esteele]
Remove GroupData’s _gruf_getProperty method, move remaining functionality into getProperty. getProperty now searches for properties in the following places: property sheets directly on the group object, PAS IPropertyProviders, portal_groupdata properties, and attributes on its GroupData entry. It returns the first piece of data found. Closes http://dev.plone.org/plone/ticket/9828 [erikrose, esteele]
Added __ignore_direct_roles__ request flag to getRolesForPrincipal() to permit retrieval of only group-provided (inherited) roles. [cah190]
getGroupsForPrincipal is a method of PAS’ IGroupsPlugin, adjust the groups tool’s plugin lookup accordingly. [esteele]
Rework the group detection of the ZODBMutablePropertyProvider so that enumerateUsers only returns users. [esteele]
Add, but don’t activate, a recursive groups plugin on installation. [esteele]
Set proper titles for default groups. [esteele]
Avoid the use of the classImplements helper from PAS. It dealt with the now gone Zope2 Interface variants and is no longer needed. [hannosch]
Fix a misnamed kwarg in autogroup plugin. [cah190]
Allow the groups tool’s searchForGroups to handle an empty search string as ‘find all’. [esteele, cah190]
Allow PASSearchView’s searchGroups method to accept a sorting option. [esteele]
Apply deiter’s patch from http://dev.plone.org/plone/ticket/9460 to prevent GroupManager’s ‘getGroupById’ from returning groups managed by other group managers. [esteele]
GroupsTool.editGroup() now stores title and description in PAS propertysheets in addition to Plone-specific tools. This helps us not pave over group titles with IDs. [erikrose]
Query the correct keyword variable for the group’s description. [esteele]
Fix an incorrect setdefault syntax. Closes http://dev.plone.org/plone/ticket/7345 [esteele]
4.0b2 - 2010-01-02
Don’t specify PIL as a direct dependencies. It is not installed as an egg on all platforms. [hannosch]
4.0b1 - 2009-12-27
Fixed package dependencies declaration. [hannosch]
4.0a2 - 2009-12-16
Added backwards compatibility alias for PloneTool to support upgrades from Plone 2.5 to work. [hannosch]
Added ‘has_email’ to the info returned by getMemberInfo. Refs http://dev.plone.org/plone/ticket/8707 [maurits]
4.0a1 - 2009-11-14
Simplified pas_member view. Also return info when no member with the requested id exists, so this can be safely used also to get “member info” for deleted members. [maurits]
Added new pas_member view, which provides easy access to the membership tools getMemberInfo method but caches the result on the request. [hannosch]
Changed the default value of memberareaCreationFlag for the membership tool to False, as it was done during Plone site creation so far. [hannosch]
Removed patch on ZODBUserManager.enumerateUsers which was introduced historical because of a former missing release of PluggableAuthService 1.5. This now superfluous patch also reduced the functionality of the patched method and introduced different behavior compared to i.e in a similar method on LDAPMultiPlugins. For details on the former patch see: http://dev.plone.org/collective/changeset/41512/PlonePAS/trunk/pas.py [jensens]
Moved a couple DTML files here from CMFPlone that got left out of the earlier refactoring. [davisagli]
Added a view of the Unauthorized exception which re-raises that exception in order to make sure that it triggers PAS’ challenge plugin rather than rendering the standard_error_message. [davisagli]
Removed deprecation warnings for various methods. These never happened. [hannosch]
Removed half-done ZCacheable caching for users and groups. [hannosch]
Removed the CMFDefault dependency of the membership tool. We only need the CMFCore functionality. [hannosch]
PlonePAS.gruf_support.authenticate method was not breaking out of the loop upon successful authenticateCredentials. [runyaga]
Changed objectIds and objectValues calls to use the IContainer API. [hannosch]
Removed parts of the outdated Extensions.Install code. [hannosch]
Removed a dependency on CMFPlone’s _createObjectByType method. [hannosch]
Removed magical homePageText lookup for initial memberarea content. You can use the notifyMemberAreaCreated hook for any kind of custom behavior. [hannosch]
Moved the scale_image function from CMFPlone.utils into our own utils module, as we are the only user of it. Also made the tests independent of any CMFPlone code. [hannosch]
Cleaned up package metadata. [hannosch]
Declare test dependencies in an extra and fixed deprecation warnings for use of Globals. [hannosch]
Switched the installation progress reporting to the logging framework. [hannosch]
Cleaned up annoying license headers in all files. We have a central place to state the license. [hannosch]
Started cleaning up deprecated methods and comments. [hannosch]
Removed support for group workspaces. This part from GRUF hasn’t been supported for many releases anymore. [hannosch]
Merged all code for the groups tool from GRUF into this package, we are officially GRUF-dependency-free :) [hannosch]
Merged all code for the group data tool from GRUF into this package. [hannosch]
Removed the GRUFBridge plugin. PAS inside GRUF isn’t supported anymore. [hannosch]
Merged tests moved from CMFPlone into the same modules as the existing tests and normalized file names. [hannosch]
Modernized tests and introduce a proper base testcase and layer. [hannosch]
Removed cookie auth tests, these don’t work anymore with plone.session. [hannosch]
Moved over all tests for the four tools from CMFPlone. [hannosch]
Removed the user folder migration code and cleaned up tests. [hannosch]
Moved all code from the four tools from CMFPlone into this package. [hannosch]
Removed ‘listed’ member property support from one of the many search functions following Plone. [hannosch]
Copied setLoginFormInCookieAuth from CMFPlone migrations. [hannosch]
Purged old Zope 2 Interface interfaces for Zope 2.12 compatibility. (only a test in this case) [elro]
3.12 - 2009-10-16
Fixed the performance fix again. enumerateUsers from mutable_properties plugin should return all the users if kw is empty. And it returns empty tuple if login or id parameter is used. [vincentfretin]
3.11 - 2009-10-05
Revert performance fix introduced in 3.10 for the mutable properties plugin. enumerateUsers shouldn’t return results if id or login is not None like in 3.9 (data dict doesn’t contain id or login key, so testMemberData returns always False). The search should be performed only if kw parameter is not empty. This is the new optimization fix. [vincentfretin]
3.10 - 2009-09-06
Performance fix for searching in the mutable properties plugin: when only searching on user id do not walk over all properties, but only test if the user id is known. This fixes http://dev.plone.org/plone/ticket/9361 [toutpt]
Nested groups are now visible in prefs_group_members. This closes http://dev.plone.org/plone/ticket/8557 [vincentfretin]
Add sort and merge PASSearchView’s interface to prevent code duplication. [csenger]
3.9 - 2009-04-21
Fix the cookie plugin’s login handler to not trust the username from the request. Instead we use the login name of the currently authenticated user. This fixes CVE-2009-0662 (see http://plone.org/products/plone/security/advisories/cve-2009-0662 for more information). [wichert]
3.8 - 2009-02-13
Update the role manager’s assignRoleToPrincipal method to lazily update the cached list of portal roles. This fixes problems with adding users with GenericSetup-created roles. [wichert]
Fixed our OrderedDict to be unpickable with pickle protocol 2. On unpickling a __init__ method is not called and an optimization in protocol 2 would call __setitem__ without the _list to be initialized. Even using a __getstate__ / __setstate__ combination wouldn’t work around that. This change was found in using membrane and MemcachedManager. [hannosch, tesdal]
3.7 - 2008-09-28
Removed deprecation zcml statements for PluggableAuthService components: these are now in PluggableAuthService itself. [wichert]
Adjusted deprecation warnings to point to Plone 4.0 instead of Plone 3.5 since we changed the version numbering again. [hannosch]
3.6 - 2008-06-25
Modify PloneGroup.getMemberIds to use all IGroupIntrospection plugins to get the group members. This makes it possible to list members in an LDAP group. [wichert]
3.5 - 2008-06-25
Make PASSearchView.merge actually merge search results. Its previous behaviour was quite nasty: it preferred search results from the enumeration plugin with the lowest priority! [wichert]
3.4 - 2008-03-26
Added BBB code for changed setLoginFormInCookieAuth upgrade method. [hannosch]
Ignore but log users without passwords during migration from pre-PAS, as these cannot be added to any standard user source. [hannosch]
Fix listRoleInfo on the role plugin to also lazily update the list of portal roles. [wichert]
3.3 - 2007-03-07
Added metadata.xml file to the profile. [hannosch]
Move global role lookup out of the local role plugin. Part of the PLIP 127 merge for Plone 3.1. [alecm]
3.2 - 2008-02-15
Fix schema handling for ZODBMutablePropertyProvider initialization. [maurits]
Remove some exception swallowing from the installation logic so errors are not hidden. [hannosch]
Correct handling an empty roles list when modifying groups. This fixes http://dev.plone.org/plone/ticket/6994 [rsantos]
3.1 - 2007-10-08
Improve handing of sorting for searches. [csenger]
Updating the roles for a group did not invalidate the _findGroup cache. [wichert]
Fixed some tool icons to point to existing icons. [hannosch]
3.0 - 2007-08-16
Fix check for authenticateCredentials return value [rossp]
3.0rc2 - 2007-07-27
Fake a getPhysicalPath on our search view so ZCacheing works properly everywhere. [wichert]
Add event classes for logged-in and logged-out events. [wichert]
3.0rc1 - 2007-07-08
Correct logic in MemberData capability methods: any plugin is allowed to (re)set a password, delete the user or add roles. [wichert]
Use the proper API to get the containing PAS in the group plugin [wichert]
Fix setting user properties on the user object. [wichert]
3.0b7 - 2007-05-05
Removed the five:registerPackage statement again. It causes problems in a ZEO environment. [hannosch]
Removed our version of the Plone tool from ToolInit. It won’t get an icon anymore and you cannot add it, but existing instances still work. We migrate all instances back to the regular tool anyways. [hannosch]
3.0b6 - 2007-05-05
Fixed two migration related test failures. [hannosch]
Spring cleaning, removed some cruft, pyflaked and corrected some more undefined names. [hannosch]
New package layout, following standard Python package conventions. [hannosch]
Fixed tool names in ToolInit, so the permission has a proper name. This closes http://dev.plone.org/plone/ticket/6525. [hannosch]
3.0-beta5 - 2007-05-02
Modify the roles plugin to lazily update its roles list from the portal. [wichert]
Filter duplicate search results. [laz, wichert]
Add a sort_by option to the search methods to allow sorting of results by a property. [laz, wichert]
Modify login method for the cookie plugin to perform the credential update in the PAS of the user instead of the PAS of the plugin. This helps in making sure that users will only authenticate against their own user folder, so we get all their roles, properties, etc. correctly. [wichert]
Update installation logic to use plone.session for cookies [wichert]
Add pas_info and pas_search browser views. [wichert]
Deprecate the PlonePAS PloneTool; its changes have been merged in the standard Plone version. [wichert]
Use getUtility to get the portal object. [wichert]
Deprecate user and group searching through CMF member and group tools in favour of PAS enumeration. [wichert]
Refactor user searching in the membership tool to use standard PAS searches. [wichert]
Add user enumeration capabilities to the mutable properties plugin. [wichert]
Add a new automatic group plugin which puts all users in a virtual group. This is useful for permissions handling: since it is not possible to add roles to users with the Authenticated role a virtual group can be used instead. [wichert]
Added support to import PloneUserFactory and added stub for ZODBMutableProperties. Attention: Latter needs a real export and import! At the moment it do not export the propertysheets. This is a TODO. At least with this two additions PlonePAS import runs. Additional I needed to hack PluginRegistry and and PluggableAuthService slightly. [jensens]
Added HISTORY.txt and updated version information. [hannosch]
2.4 - 2007-04-15
Optomise the local roles plugin for the common case where local_roles is empty [dreamcatcher]
the plone user was assuming a one to one mapping between property plugin and user property sheet, and stripping away additional ones as part of the retrieval of ordered sheets, instead, it now stores all propertysheets in an ordered dictionary, so this assumption is not needed [k_vertigo]
More postonly security changes [alecm, ramon]
2.3 - 2007-05-30
Use a local postonly decorator so PlonePAS can be used with Plone 2.5, 2.5.1 and 2.5.2. [wichert]
Protect the tools with postonly security modifiers. [mj]
Update GRUF compatibility functions to use the same security checks as GRUF itself uses. [mj]
Fix migration to handle properties of selection or multiple selection types. [reinout]
Correct creation of groups wich default group managers. [dreamcatcher]
Fix migration from GRUF sites: also include the member properties in the migration. [tesdal]
Correct the test for creation of groups with the same id as users: search for the exact id, not substrings. [tesdal]
Fix bad form action which made it impossible to add a plone user factory plugin through the ZMI. Backported from trunk. [wichert]
