dc668b1b6a baseldap: Fix possible crash in LDAPObject.handle_duplicate_entry 2015-05-15 14:28:52 +00:00
Petr Vobornik
4364ac08c5 speed up indirect member processing
the old implementation tried to get all entries which are member of group.
That means also user. User can't have any members therefore this costly
processing was unnecessary.

New implementation reduces the search only to entries which have members.

Also page size was removed to avoid paging by small pages(default size: 100)
which is very slow for many members.

e11e8235ac baseldap: Handle missing parent objects properly in *-find commands
The find_entries function in ipaldap does not differentiate between
a LDAP search that returns error code 32 (No such object) and LDAP
search returning error code 0 (Success), but returning no results.

In both cases errors.NotFound is raised. In turn, LDAPSearch
commands interpret NotFound exception as no results.

To differentiate between the cases, a new error EmptyResult
was added, which inherits from NotFound to preserve the compatibility
with the new code.

This error is raised by ipaldap.find_entries in case it is performing
a search with and the target dn does not exist.

59ee6314af keytab manipulation permission management
Adds new API:

  ipa host-disallow-retrieve-keytab HOSTNAME --users=STR --groups STR
  ipa host-allow-create-keytab HOSTNAME --users=STR --groups STR

  ipa service-disallow-retrieve-keytab PRINCIPAL --users=STR --groups STR
  ipa service-allow-create-keytab PRINCIPAL --users=STR --groups STR
  ipa service-disallow-create-keytab PRINCIPAL --users=STR --groups STR

these methods add or remove user or group DNs in `ipaallowedtoperform` attr with
`read_keys` and `write_keys` subtypes.

service|host-mod|show outputs these attrs only with --all option as:

  Users allowed to retrieve keytab: user1
  Groups allowed to retrieve keytab: group1
  Users allowed to create keytab: user1
  Groups allowed to create keytab: group1

Adding of object class is implemented as a reusable method since this code is
used on many places and most likely will be also used in new features. Older
code may be refactored later.

66356f0daf Improve error messages for external group members

Similarly, when trying to delete an entry which is not a member,
an error message is issued, informing the user that the entry is not
a member of the group. These error messages were missing in case of
external members.

This patch also adds support for using the AD\name or name@ad.domain.com
format in ipa group-remove-member command. This format was supported in

941d1e8701 Do not produce unindexed search on every DEL command
Every <plugin>-del command executes an "(objectclass=*)" search
to find out if a deleted node has any child nodes which would need
to be deleted first. This produces an unindexed search for every del
command which biases access log audits and may affect performance too.

Since most of the *-del commands delete just a single object (user,
group, RBAC objects, SUDO or HBAC objects, ...) and not a tree
(automount location, dns zone, ...) run a single entry delete first
and only revert to subtree search&delete when that fails.

94d457e83c Use DN objects instead of strings
* Convert every string specifying a DN into a DN object

* Every place a dn was manipulated in some fashion it was replaced by
  the use of DN operators

* Add new DNParam parameter type for parameters which are DN's

* DN objects are used 100% of the time throughout the entire data
  pipeline whenever something is logically a dn.

* Many classes now enforce DN usage for their attributes which are
  dn's. This is implmented via ipautil.dn_attribute_property(). The
  only permitted types for a class attribute specified to be a DN are
  either None or a DN object.

* Require that every place a dn is used it must be a DN object.
  This translates into lot of::

    assert isinstance(dn, DN)

  sprinkled through out the code. Maintaining these asserts is
  valuable to preserve DN type enforcement. The asserts can be
  disabled in production.

  The goal of 100% DN usage 100% of the time has been realized, these
  asserts are meant to preserve that.

  The asserts also proved valuable in detecting functions which did
  not obey their function signatures, such as the baseldap pre and
  post callbacks.

* Moved ipalib.dn to ipapython.dn because DN class is shared with all
  components, not just the server which uses ipalib.

* All API's now accept DN's natively, no need to convert to str (or
  unicode).

* Removed ipalib.encoder and encode/decode decorators. Type conversion
  is now explicitly performed in each IPASimpleLDAPObject method which
  emulates a ldap.SimpleLDAPObject method.

* Entity & Entry classes now utilize DN's

* Removed __getattr__ in Entity & Entity clases. There were two
  problems with it. It presented synthetic Python object attributes
  based on the current LDAP data it contained. There is no way to
  validate synthetic attributes using code checkers, you can't search
  the code to find LDAP attribute accesses (because synthetic
  attriutes look like Python attributes instead of LDAP data) and
  error handling is circumscribed. Secondly __getattr__ was hiding
  Python internal methods which broke class semantics.

* Replace use of methods inherited from ldap.SimpleLDAPObject via
  IPAdmin class with IPAdmin methods. Directly using inherited methods
  was causing us to bypass IPA logic. Mostly this meant replacing the
  use of search_s() with getEntry() or getList(). Similarly direct
  access of the LDAP data in classes using IPAdmin were replaced with
  calls to getValue() or getValues().

* Objects returned by ldap2.find_entries() are now compatible with
  either the python-ldap access methodology or the Entity/Entry access
  methodology.

* All ldap operations now funnel through the common
  IPASimpleLDAPObject giving us a single location where we interface
  to python-ldap and perform conversions.

* The above 4 modifications means we've greatly reduced the
  proliferation of multiple inconsistent ways to perform LDAP
  operations. We are well on the way to having a single API in IPA for
  doing LDAP (a long range goal).

* All certificate subject bases are now DN's

* DN objects were enhanced thusly:
  - find, rfind, index, rindex, replace and insert methods were added
  - AVA, RDN and DN classes were refactored in immutable and mutable
    variants, the mutable variants are EditableAVA, EditableRDN and
    EditableDN. By default we use the immutable variants preserving
    important semantics. To edit a DN cast it to an EditableDN and
    cast it back to DN when done editing. These issues are fully
    described in other documentation.
  - first_key_match was removed
  - DN equalty comparison permits comparison to a basestring

* Fixed ldapupdate to work with DN's. This work included:
  - Enhance test_updates.py to do more checking after applying
    update. Add test for update_from_dict(). Convert code to use
    unittest classes.
  - Consolidated duplicate code.
  - Moved code which should have been in the class into the class.
  - Fix the handling of the 'deleteentry' update action. It's no longer
    necessary to supply fake attributes to make it work. Detect case
    where subsequent update applies a change to entry previously marked
    for deletetion. General clean-up and simplification of the
    'deleteentry' logic.
  - Rewrote a couple of functions to be clearer and more Pythonic.
  - Added documentation on the data structure being used.
  - Simplfy the use of update_from_dict()

* Removed all usage of get_schema() which was being called prior to
  accessing the .schema attribute of an object. If a class is using
  internal lazy loading as an optimization it's not right to require
  users of the interface to be aware of internal
  optimization's. schema is now a property and when the schema
  property is accessed it calls a private internal method to perform
  the lazy loading.

* Added SchemaCache class to cache the schema's from individual
  servers. This was done because of the observation we talk to
  different LDAP servers, each of which may have it's own
  schema. Previously we globally cached the schema from the first
  server we connected to and returned that schema in all contexts. The
  cache includes controls to invalidate it thus forcing a schema
  refresh.

* Schema caching is now senstive to the run time context. During
  install and upgrade the schema can change leading to errors due to
  out-of-date cached schema. The schema cache is refreshed in these
  contexts.

* We are aware of the LDAP syntax of all LDAP attributes. Every
  attribute returned from an LDAP operation is passed through a
  central table look-up based on it's LDAP syntax. The table key is
  the LDAP syntax it's value is a Python callable that returns a
  Python object matching the LDAP syntax. There are a handful of LDAP
  attributes whose syntax is historically incorrect
  (e.g. DistguishedNames that are defined as DirectoryStrings). The
  table driven conversion mechanism is augmented with a table of
  hard coded exceptions.

  Currently only the following conversions occur via the table:

  - dn's are converted to DN objects

  - binary objects are converted to Python str objects (IPA
    convention).

  - everything else is converted to unicode using UTF-8 decoding (IPA
    convention).

  However, now that the table driven conversion mechanism is in place
  it would be trivial to do things such as converting attributes
  which have LDAP integer syntax into a Python integer, etc.

* Expected values in the unit tests which are a DN no longer need to
  use lambda expressions to promote the returned value to a DN for
  equality comparison. The return value is automatically promoted to
  a DN. The lambda expressions have been removed making the code much
  simpler and easier to read.

* Add class level logging to a number of classes which did not support
  logging, less need for use of root_logger.

* Remove ipaserver/conn.py, it was unused.

* Consolidated duplicate code wherever it was found.

* Fixed many places that used string concatenation to form a new
  string rather than string formatting operators. This is necessary
  because string formatting converts it's arguments to a string prior
  to building the result string. You can't concatenate a string and a
  non-string.

* Simplify logic in rename_managed plugin. Use DN operators to edit
  dn's.

* The live version of ipa-ldap-updater did not generate a log file.
  The offline version did, now both do.

9960149e3f Rework the CallbackInterface
Fix several problems with the callback interface:
- Automatically registered callbacks (i.e. methods named
    exc_callback, pre_callback etc) were registered on every
    instantiation.
    Fix: Do not register callbacks in __init__; instead return the
    method when asked for it.
- The calling code had to distinguish between bound methods and
    plain functions by checking the 'im_self' attribute.
    Fix: Always return the "default" callback as an unbound method.
    Registered callbacks now always take the extra `self` argument,
    whether they happen to be bound methods or not.
    Calling code now always needs to pass the `self` argument.
- Did not work well with inheritance: due to the fact that Python
    looks up missing attributes in superclasses, callbacks could
    get attached to a superclass if it was instantiated early enough. *
    Fix: Instead of attribute lookup, use a dictionary with class keys.
- The interface included the callback types, which are LDAP-specific.
    Fix: Create generic register_callback and get_callback mehods,
    move LDAP-specific code to BaseLDAPCommand

Update code that calls the callbacks.

json_metadata command creates and sends metadata needed by Web UI. It uses __json__ method for serialization of commands, options, objects... . A lot of data sent was useless for Web UI and some usefull information were missing. We
 * mostly CLI specific option attribues are not send.
 * attributes evaluated to false or None are not send
 * options which are send are not got from takes_aptions attribute but by get_options() method. It finally sends usefull option collection for commands part of metadata.

In the end the raw amount of data send is aproximately the same.

This patch is needed for Web UI to determine which option it can use in which commands.
