config-mod is capable of changing default SELinux user map order
and a default SELinux user. Validate the new config values to
prevent bogus default SELinux users to be assigned to IPA users.

When there were no updated attrs when modifying a nonexistent DNS record,
the error was not handled and caused an internal server error later (old_entry
was used uninitialized).
https://fedorahosted.org/freeipa/ticket/3055
When a new reverse zone is to be generated based on an IP address without
a network prefix length, we need to use some default value. While netaddr
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.
Test case has been added to cover the new default.

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.

When ADD command is being executed and a single-value object attribute
is being set with both option and addattr IPA ends up in an internal
error.
Make better value sanitizing job in this case and let IPA throw
a user-friendly error. Unit test exercising this situation is added.
https://fedorahosted.org/freeipa/ticket/2429
Both selinuxusermap-add and selinuxusermap-mod commands now behave
consistently in not allowing user/host category or user/host members
and HBAC rule being set at the same time. Also adds a bunch of unit
tests that check this behaviour.
https://fedorahosted.org/freeipa/ticket/2983
Public keys in the old format (raw RFC 4253 blob) are automatically
converted to OpenSSH-style public keys. OpenSSH-style public keys are now
stored in LDAP.
Changed sshpubkeyfp to be an output parameter, as that is what it actually
is.
Allow parameter normalizers to be used on values of any type, not just
unicode, so that public key blobs (which are str) can be normalized to
OpenSSH-style public keys.
ticket 2932, 2935
range_mod and range_del command could easily create objects with
ID which is suddenly out of specified range. This could cause issues
in trust scenarios where range objects are used for computation of
remote IDs.
Add validator for both commands to check if there is any object with
ID in the range which would become out-of-range as a pre_callback.
Also add unit tests testing this new validator.
https://fedorahosted.org/freeipa/ticket/2919
Password policies in pwpolicy-find are now sorted in the expected
numerical manner. Also tweaks one of the unit tests so that it
tests this behaviour.
https://fedorahosted.org/freeipa/ticket/3039
Currently, we throw many public exceptions without proper i18n.
Wrap natural-language error messages in _() so they can be translated.
In the service plugin, raise NotFound errors using handle_not_found helper
so the error message contains the offending service.
Use ScriptError instead of NotFoundError in bindinstance install.
https://fedorahosted.org/freeipa/ticket/1953
We prevent the last member of the admin group from being deleted. The
same check needs to be performed when disabling a user.
* Moved the code in del_user to the common subroutine
check_protected_member() and call it from both user_del and
user_disable. Note, unlike user_del user_disable does not have a
'pre' callback therefore the check function is called in
user_disable's execute routine.
* Make check_protected_member() aware of disabled members. It's not
sufficient to check which members of the protected group are
present, one must only consider those members which are enabled.
* Add tests to test_user_plugin.py.
- verify you cannot delete nor disable the last member of the admin
group
- verify when the admin group contains disabled users in addition to
enabled users only the enabled users are considered when
determining if the last admin is about to be disabled or deleted.
* Replace duplicated hardcoded values in the tests with variables or
subroutines, this makes the individual tests a bit more succinct and
easier to copy/modify.
* Update error msg to reflect either deleting or disabling is an error.
https://fedorahosted.org/freeipa/ticket/2979
The manager LDAP attribute is a dn pointing inside the user
container. When passed on the command it is typically a bare user
uid. The search filter will only succeed if the bare uid is converted
to a full dn because that is what is stored in the value for the
manager attribute.
The search failure is solved by calling _normalize_manager() which
does the conversion to a dn (if not already a dn).
It feels like this type of conversion should be performed in the pre
callback which allows one to modify the filter. But when the pre
callback is invoked it's complex string with the manager attribute
already inserted. This is because the LDAPSearch.execute() method
processes the options dict and constructs a filter component for each
key/value in the options dict prior to invoking the pre callback. If
we wanted to modify the manager value in the filter in the pre
callback we would have to decompose the filter string, perform dn
checking and then reassemble the filter. It's much cleaner to perform
the dn operations on the manager value before it gets embedded into
what otherwise might be a very complex filter. This is the reason why
the normalization is perfored in the execute method as opposed to the
pre callback. Other classes do similar things in their execute methods
as opposed to their callbacks's, selinuxusermap_find is one example.
Patch also introduces new unit test to verify.
https://fedorahosted.org/freeipa/ticket/2264
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.
* 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.

We need to compare two values and need to be aware of where those
values are coming from. They may come from options, setattr or
existing config. The format of that data is going to be different
depending on its source (always a list internally).
One may also set both at the same time so a standard validator cannot
be used because it lacks the context of the other value being set.

The .po files we use for translations have two shortcomings when used in Git:
- They include file locations, which change each time the source is updated.
This results in large, unreadable diffs that don't merge well.
- They include source strings for untranslated messages, wasting space
unnecessarily.
Update the Makefile so that the extraneous information is stripped when the
files are updated or pulled form Transifex, and empty translation files are
removed entirely.
Also, translations are normalized to a common style. This should help diffs
and merges.
The validator requires file location comments to identify the programming
language, and to produce good error reports.
To make this work, merge the comments in before validation.
First patch for: https://fedorahosted.org/freeipa/ticket/2435
RFC 1912 states that no record (besides PTR) is allowed to coexist
with any other record type. When BIND detects this situation, it
refuses to load such records.
Enforce the constrain for dnsrecord-mod and dnsrecord-add commands.
https://fedorahosted.org/freeipa/ticket/2601
range plugin was missing range-mod command that could be used for
example to fix a size for a range generated during upgrades. The
range should be updated with a caution though, a misconfiguration
could break trusts.
iparangetype is now also handled better and filled in all commands
instead of just range-show. objectclass attribute is deleted only
when really needed now.
The Batch command did not report errors correctly: it reported
the text of *all* errors, not just PublicError, used unicode(e)
instead of e.strerror (which results in incorrect i18n), and only
reported the text of error messages, not their type and code.
Fix these problems. Update tests.

When using ipaExternalGroup/ipaExternalMember attributes it is
possible to add group members which don't exist in IPA database.
This is primarily is required for AD trusts support and therefore
validation is accepting only secure identifier (SID) format.

IPA implements read/write permissions for DNS record or zones.
Provided set of permissions and privileges can, however, only grant
access to the whole DNS tree, which may not be appropriate.
Administrators may miss more fine-grained permissions allowing
them to delegate access per-zone.
Create a new IPA auxiliary objectclass ipaDNSZone allowing
a managedBy attribute for a DNS zone. This attribute will hold
a group DN (in this case a permission) which allows its members
to read or write in a zone. Member permissions in given zone
will only have 2 limitations:
1) Members cannot delete the zone
2) Members cannot edit managedBy attribute
Current DNS deny ACI used to enforce read access is removed so that
DNS privileges are based on allow ACIs only, which is much more
flexible approach as deny ACIs have always precedence and limit
other extensions. Per-zone access is allowed in 3 generic ACIs
placed in cn=dns,$SUFFIX so that no special ACIs has to be added
to DNS zones itselves.
2 new commands have been added which allows an administrator to
create the system permission allowing the per-zone access and
fill a zone's managedBy attribute:
* dnszone-add-permission: Add per-zone permission
* dnszone-remove-permission: Remove per-zone permission

When unknown keyword arguments are passed to a Command, raise an
error instead of ignoring them.
Options used when IPA calls its commands internally are listed
in a new Command attribute called internal_options, and allowed.
Previous patches (0b01751c, c45174d6, c5689e7f) made IPA not use
unknown keyword arguments in its own commands and tests, but since
that some violations were reintroduced in permission_find and tests.
Fix those.
Tests included; both a frontend unittest and a XML-RPC test via the
ping plugin (which was untested previously).
https://fedorahosted.org/freeipa/ticket/2509
Parameter Decimal does not have a sufficient value checks. Some values
cause Decimal parameter with a custom precision to crash with
an unhandled exception.
Improve parameter conversion and normalization operations to handle
decimal exceptions more gracefully. Decimal parameter now also has
new attributes enabling 2 new validation/normalization methods:
* exponential: when False, decimal number is normalized to its
non-exponential form
* numberclass: a set of allowed decimal number classes
(e.g. +Infinity, -Normal, ...) that are enforced
for every Decimal parameter value

Try to use the URI /ipa/session/xml if there is a key in the kernel
keyring. If there is no cookie or it turns out to be invalid (expired,
whatever) then use the standard URI /ipa/xml. This in turn will create
a session that the user can then use later.
https://fedorahosted.org/freeipa/ticket/2331
Trust work that was pushed recently requires few changes in unit
tests to prevent test failures. This patch also removes repetitive
construction of group DN in group unit tests.
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.
Add tests.
Remove lint exceptions for CallbackInterface.

IPA server web form-based authentication allows logins for users
which for some reason cannot use Kerberos authentication. However,
when a password for such users expires, they are unable change the
password via web interface.
This patch adds a new WSGI script attached to URL
/ipa/session/change_password which can be accessed without
authentication and which provides password change capability
for web services.
The actual password change in the script is processed by LDAP
password change command.
Password result is passed both in the resulting HTML page, but
also in HTTP headers for easier parsing in web services:
X-IPA-Pwchange-Result: {ok, invalid-password, policy-error, error}
(optional) X-IPA-Pwchange-Policy-Error: $policy_error_text

For security reasons, dynamic updates are not enabled for new DNS
zones. In order to enable the dynamic zone securely, user needs to
allow dynamic updates and create a zone update policy.
The policy is not easy to construct for regular users, we should
rather fill it by default and let users just switch the policy
on or off.

This adds tests for the automountlocation_tofiles and
automountlocation_import commands, and to automountmap_add_indirect
with the --parentmap option.
The tofiles test checks not only the XML-RPC output, but also the
output_for_cli method.
The import tests load data from tofiles output to the directory
and check that tofiles output matches.
This only works when all maps are connected to auto.master.
Two minor touches to the automount plugin itself: remove an extra
space, and don't hide the traceback when re-raising an exception.
Precallback validator was failing when a zone-relative name was
used as a NS record (for example record "ns" in a zone "example.com").
However, this is valid in BIND and we should allow it as well.
Imports in dns module had to be switched to absolute imports
(available from Python 2.5) to deal with a conflict of IPA dns
module and dnspython module.
https://fedorahosted.org/freeipa/ticket/2630
When permission-find post callback detected a --pkey-only option,
it just terminated. However, this way the results that could have
been added from aci_find matches were not included.
Fix the post callback to go through the entire matching process.
Also make sure that DNS permissions have a correct objectclass
(ipapermission), otherwise such objects are not matched by the
permission LDAP search.
https://fedorahosted.org/freeipa/ticket/2658
We actually perform two searches in permission-find. The first looks
for matches within the permission object itself. The second looks at
matches in the underlying aci.
We need to break out in two places. The first is if we find enough
matches in the permission itself. The second when we are appending
matches from acis.
The post_callback() definition needed to be modified to return
the truncated value so a plugin author can modify that value.
