John Dennis 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().

John Dennis 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.

Adam Young 5ee93349f6 enable proxy for dogtag
Dogtag is going to be proxied through httpd.  To make this work, it has to support renegotiation of the SSL
connection.  This patch enables renegotiate in the nss configuration file during during apache configuration,
as well as modifies libnss to set the appropriate optins on the ssl connection in order to  renegotiate.

The IPA install uses the internal ports instead of proxying through
httpd since  httpd is not set up yet.

IPA needs to Request the certificate through a port that uses authentication.  On the Dogtag side, they provide an additional mapping for this:   /ca/eeca/ca as opposed tp /ca/ee/ca  just for this purpose.

https://fedorahosted.org/freeipa/ticket/1334

add flag to pkicreate in order to enable using proxy.

add the proxy file in  /etc/http/conf.d/

Nalin Dahyabhai df0b927bfb Select a server with a CA on it when submitting signing requests.
When the RA is about to submit a signing request to a CA, check
if the ca_host is actually a CA.  If it isn't, and it isn't the
local host, check if the local host is a CA.  If that doesn't
work, try to select a CA host at random.  If there aren't any,
just give up and pretend the ca_host is a CA so that we can fail
to connect to it, as we would have before.

Jakub Hrozek 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

Rob Crittenden 70049496e3 Remove older MITM fixes to make compatible with dogtag 1.3.3
We set a new port to be used with dogtag but IPA doesn't utilize it.

This also changes the way we determine which security database to use.
Rather than using whether api.env.home is set use api.env.in_tree.

John Dennis b75d06e189 localize doc strings
A number of doc strings were not localized, wrap them in _().
Some messages were not localized, wrap them in _()

Fix a couple of failing tests:
The method name in RPC should not be unicode.
The doc attribute must use the .msg attribute for comparison.

Also clean up imports of _() The import should come from
ipalib or ipalib.text, not ugettext from request.

Rob Crittenden 8a4ab2a0e5 Move the HTTP/S request code to a common library
This moves code that does HTTP and HTTPS requests into a common library
that can be used by both the installer and the dogtag plugin.

These functions are not generic HTTP/S clients, they are designed
specifically to talk to dogtag, so use accordingly.

Rob Crittenden b7cda86697 Update dogtag configuration to work after CVE-2009-3555 changes
NSS is going to disallow all SSL renegotiation by default. Because of
this we need to always use the agent port of the dogtag server which
always requires SSL client authentication. The end user port will
prompt for a certificate if required but will attempt to re-do the
handshake to make this happen which will fail with newer versions of NSS.

Rob Crittenden b8016807eb Use the caIPAserviceCert profile for issuing service certs.
This profile enables subject validation and ensures that the subject
that the CA issues is uniform. The client can only request a specific
CN, the rest of the subject is fixed.

This is the first step of allowing the subject to be set at
installation time.

Also fix 2 more issues related to the return results migration.

Rob Crittenden 49b36583a5 Add external CA signing and abstract out the RA backend
External CA signing is a 2-step process. You first have to run the IPA
installer which will generate a CSR. You pass this CSR to your external
CA and get back a cert. You then pass this cert and the CA cert and
re-run the installer. The CSR is always written to /root/ipa.csr.

A run would look like:

 # ipa-server-install --ca --external-ca -p password -a password -r EXAMPLE.COM -u dirsrv -n example.com --hostname=ipa.example.com -U
[ sign cert request ]
 # ipa-server-install --ca --external-ca -p password -a password --external_cert_file=/tmp/rob.crt --external_ca_file=/tmp/cacert.crt  -U -p password -a password -r EXAMPLE.COM -u dirsrv -n example.com --hostname=ipa.example.com

This also abstracts out the RA backend plugin so the self-signed CA we
create can be used in a running server. This means that the cert plugin
can request certs (and nothing else). This should let us do online replica
creation.

To handle the self-signed CA the simple ca_serialno file now contains
additional data so we don't have overlapping serial numbers in replicas.
This isn't used yet. Currently the cert plugin will not work on self-signed
replicas.

One very important change for self-signed CAs is that the CA is no longer
held in the DS database. It is now in the Apache database.

Lots of general fixes were also made in ipaserver.install.certs including:
 - better handling when multiple CA certificates are in a single file
 - A temporary directory for request certs is not always created when the
   class is instantiated (you have to call setup_cert_request())
