7ce6c4a2d3 Make service naming in ipa-server-install consistent
Forces more consistency into ipa-server-install output. All
descriptions of services that are not instances of
SimpleServiceInstance are now in the following format:

<Description> (<Service Name>)

Furthermore, start_creation method has been modified to support
custom start and end messages. See documentation for more info.

38bbbdea61 log dogtag errors
If we get an error from dogtag we always did raise a
CertificateOperationError exception with a message describing the
problem. Unfortuanately that error message did not go into the log,
just sent back to the caller. The fix is to format the error message
and send the same message to both the log and use it to initialize the
CertificateOperationError exception. This is done in the utility
method raise_certificate_operation_error().

0840b588d7 Add cifs principal to S4U2Proxy targets only when running ipa-adtrust-install
Since CIFS principal is generated by ipa-adtrust-install and is only

2ca7bb3134 Fix CS replication management.
The master side should be on the local side, replica1, not the
remote. This required reversing a few master variables. This impacts
the naming of the replication agreements.

When deleting an agreement pass in the DN of that agreement
rather than trying to calculate what it is on-the-fly. We cannot
be sure which side is the master/clone and since we search for it
anyway to determine if the agreement exists it is more correct
to use what we find.

The force flag wasn't being passed into del_link so there was no way
to force a deletion.

74ebd0fd75 Move CRL publish directory to IPA owned directory
Currently, CRL files are being exported to /var/lib/pki-ca
sub-directory, which is then served by httpd to clients. However,
this approach has several disadvantages:
 * We depend on pki-ca directory structure and relevant permissions.
   If pki-ca changes directory structure or permissions on upgrade,
   IPA may break. This is also a root cause of the latest error, where
   the pki-ca directory does not have X permission for others and CRL
   publishing by httpd breaks.
 * Since the directory is not static and is generated during
   ipa-server-install, RPM upgrade of IPA packages report errors when
   defining SELinux policy for these directories.

Move CRL publish directory to /var/lib/ipa/pki-ca/publish (common for
both dogtag 9 and 10) which is created on RPM upgrade, i.e. SELinux policy
configuration does not report any error. The new CRL publish directory
is used for both new IPA installs and upgrades, where contents of
the directory (CRLs) is first migrated to the new location and then the
actual configuration change is made.

247a3a43b7 Build and installation of Kerberos authentication extension
This patch is adding a build of kerberosauth.xpi (FF Kerberos authentication extension).

Currently the build is done in install phase of FreeIPA server. It is to allow signing of the extension by singing certificate. The signing might not be necessary because the only outcome is that in extension installation FF doesn't show that the maker is not verified. It shows text: 'Object signing cert'. This might be a bug in httpinstance.py:262(db.create_signing_cert("Signing-Cert", "Object Signing Cert", ca_db)) The value is in place of hostname parameter.

If the extension is not signed, it can be created in rpm build phase, which should make upgrades easier. Current implementation doesn't handle upgrades yet.

In order to keep extension and config pages not dependent on a realm, a krb.js.teplate file was created. This template is used for creating a /usr/share/ipa/html/krb.js file in install phase which holds FreeIPA's realm and domain information. This information can be then used by config pages by importing this file.

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.

ef7b8ab764 Use default reverse zone consistently
When a new reverse zone is to be generated based on an IP address without

library default ones (32b for IPv4 and 128b for IPv6) are not very sensible
we should use the defaults already applied in installers. That is 24b for
IPv6 and 64 for IPv6.

c0630950a1 Expand Referential Integrity checks
Many attributes in IPA (e.g. manager, memberuser, managedby, ...)
are used to store DNs of linked objects in IPA (users, hosts, sudo
commands, etc.). However, when the linked objects is deleted or
renamed, the attribute pointing to it stays with the objects and
thus may create a dangling link causing issues in client software
reading the data.

Directory Server has a plugin to enforce referential integrity (RI)
by checking DEL and MODRDN operations and updating affected links.
It was already used for manager and secretary attributes and
should be expanded for the missing attributes to avoid dangling
links.

As a prerequisite, all attributes checked for RI must have pres
and eq indexes to avoid performance issues. Thus, the following
indexes are added:
  * manager (pres index only)
  * secretary (pres index only)
  * memberHost
  * memberUser
  * sourcehost
  * memberservice
  * managedby
  * memberallowcmd
  * memberdenycmd
  * ipasudorunas
  * ipasudorunasgroup

Referential Integrity plugin is updated to enforce RI for all these
attributes. Unit tests covering RI checks for all these attributes
were added as well.

Note: this update will only fix RI on one master as RI plugin does
not check replicated operations.

917a480675 Add safe updates for objectClasses
Current objectclass updates in a form of "replace" update instruction
dependent on exact match of the old object class specification in the
update instruction and the real value in LDAP. However, this approach is
very error prone as object class definition can easily differ as for
example because of unexpected X-ORIGIN value. Such objectclass update
failures may lead to serious malfunctions later.

When comparing the objectclasses, make sure we normalize them both
before we compare them to mitigate these kinds of errors. python-ldap's
objectclass model can be utilized to do the normalization part.

One objectclass update instruction was changed to do a replace of
an objectclass separately from add update instruction so that we
really only replace what's stored in LDAP.

1328f984d0 Ticket #3008: DN objects hash differently depending on case
Because the attrs & values in DN's, RDN's and AVA's are comparison case-
insensitive the hash value between two objects which compare as equal but
differ in case must also yield the same hash value. This is critical when
these objects are used as a dict key or in a set because dicts and sets
use the object's __hash__ value in conjunction with the objects __eq__
method to lookup the object.

The defect is the DN, RDN & AVA objects computed their hash from the case-
preserving string representation thus two otherwise equal objects
incorrectly yielded different hash values.

The problem manifests itself when one of these objects is used as a key in
a dict, for example a dn.

dn1 = DN(('cn', 'Bob'))
dn2 = DN(('cn', 'bob'))

dn1 == dn2 --> True

hash(dn1) == hash(dn2) --> False

d = {}

d[dn1] = x
d[dn2] = y

len(d) --> 2

The patch fixes the above by lower casing the string representation of
the object prior to computing it's hash.

The patch also corrects a spelling mistake and a bogus return value in
ldapupdate.py which happened to be discovered while researching this
bug.

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.

1be46b322f Handle exceptions when establishing trusts
Translate exceptions produced by DCERPC bindings when establishing trusts.
There are two types of errors that may be produced by DCERPC bindings:
- RuntimeError with a text (RuntimeError('NT_STATUS_OBJECT_NAME_NOT_FOUND')
- RuntimeError with a numeric code and 'friendly' message

Error codes could have two prefixes:
  - NT error codes, start with NT_STATUS_ prefix
  - Windows error codes, start with WERR_ prefix

Full list of errors is available in Samba source code:
  libcli/util/ntstatus.h: NT_STATUS error codes
  libcli/util/werror.h: Windows error codes

Majority of errors returned when dealing with trusts are of NT_STATUS type,
these also include all typical POSIX errors mapped to corresponding NT errors.

Unfortunately, in the textual RuntimeError case very little can be done to
get better clarification of the error. More error paths will need to be added
as they will be discovered -- DCERPC error messaging is complex.
