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.

6d0e4e58fc Fix expected error messages in tests
Have the test suite check error messages.
Since XMLRPC doesn't give us structured error information, just
compare the resulting text.
Fix messages that tests expect to cause.

Minor changes:

Make netgroup-mod's NotFound message consistent with other objects
and methods.

In test_automember_plugin, test with nonexistent automember rules
of both types, instead of nonexistent users.

0b01751c1b Use valid argument names in tests
Some of our tests used unintended extra options, or options with
misspelled, wrongly copy-pasted or otherwise bad names. These are
ignored, so the intended argument was treated as missing. The test
itself can still pass but may be rendered ineffective or fragile.

This only fixes those of such errors that appear in the test suite.
Fixing code in the framework and actual rejecting of unknown
arguments is deferred for later (ticket #2509).

dddebe2350 Only split CSV in the client, quote instead of escaping
Splitting on commas is not an idempotent operation:
'a,b\,c' -> ('a', 'b,c') -> ('a', 'b', 'c')

That means we can't do it when the call is forwarded, so this is only
done on the CLI. The UI already sends values as a tuple.

Replace escaping in the csv parser with quoting. Quoted strings can have
embedded commas instead of having to escape them. This prevents the csv
parser from eating all escape characters.

Also, document Param's csv arguments, and update tests.

616d543a54 Memberof attribute control and update
Checking of parameters used by _make_aci funcion was rewritten.
Additional attributes of ACI(type, attribute, memberof, targetgroup,
subtree, filter) could be unset.

Permission plugin now allows to unset memberof value.
https://fedorahosted.org/freeipa/ticket/2255

Added checking of existence of groups that are specified in permission
and delegation module.

cf12f3106a Fix raw format for ACI commands
ACI plugins (permission, selfservice and delegation) were not
prepared to serve ACIs in a raw format, i.e. raw "aci" attribute
taken from LDAP. This patch fixes all these plugins and their
commands to provide provide this format. Few ACI raw format unit
tests were added for all these plugins.

7f6c9ac04c Add missing --pkey-only option for selfservice and delegation
pkey-only functionality has to be implemented separately for these
modules as they are based on crud.Search instead of standard
LDAPSearch.

Delegation moduled was also fixed to support new format of ACI's
memberof attribute introduced in patch "Display the value of
memberOf ACIs in permission plugin."

4b7e5721d4 Fix changing membergroup in a delegation.
This is mostly due to inconsistent option name usage but also due
to the aci plugin not always treating memberof as a special kind
of filter.

7493d781df Change FreeIPA license to GPLv3+
The changes include:
 * Change license blobs in source files to mention GPLv3+ not GPLv2 only
 * Add GPLv3+ license text
 * Package COPYING not LICENSE as the license blobs (even the old ones)
   mention COPYING specifically, it is also more common, I think

34534a026f Don't use camel-case LDAP attributes in ACI and don't clear enrolledBy
We keep LDAP attributes lower-case elsewhere in the API we should do the
same with all access controls.

There were two ACIs pointing at the manage_host_keytab permission. This
isn't allowed in general and we have decided separately to not clear out
enrolledBy when a host is unenrolled so dropping it is the obvious thing
to do.

cd7b64103b Add group to group delegation plugin.
This is a thin wrapper around the ACI plugin that manages granting group A
the ability to write a set of attributes of group B.
