This also constitutes a rethinking of the token ACIs after the introduction
of SELFDN support.
Admins, as before, have full access to all token permissions.
Normal users have read/search/compare access to all of the non-secret data
for tokens assigned to them, whether managed by them or not. Users can add
tokens if, and only if, they will also manage this token.
Managers can also read/search/compare tokens they manage. Additionally,
they can write non-secret data to their managed tokens and delete them.
When a normal user self-creates a token (the default behavior), then
managedBy is automatically set. When an admin creates a token for another
user (or no owner is assigned at all), then managed by is not set. In this
second case, the token is effectively read-only for the assigned owner.
This behavior enables two important other behaviors. First, an admin can
create a hardware token and assign it to the user as a read-only token.
Second, when the user is deleted, only his self-managed tokens are deleted.
All other (read-only) tokens are instead orphaned. This permits the same
token object to be reasigned to another user without loss of any counter
data.

This is a Web UI wide change. Fields and Widgets binding was refactored

independent on each other. So that one could use a widget without field
or use one field for multiple widgets, etc..
Basically a fields logic was split into separate components:
- adapters
- parsers & formatters
- binder
Adapters
- extract data from data source (FreeIPA RPC command result)
- prepares them for commands.
Parsers
- parse extracted data to format expected by field
- parse widget value to format expected by field
Formatters
- format field value to format suitable for widgets
- format field value to format suitable for adapter
Binder
- is a communication bridge between field and widget
- listens to field's and widget's events and call appropriate methods

allowed to access IPA realm.
We also should really use 'cn' of the entry as domain name.
ipaNTTrustPartner has different meaning on wire, it is an index
pointing to the parent domain of the domain and will be 0 for top
level domains or disjoint subdomains of the trust.
Finally, trustdomain-enable and trustdomain-disable commands should
force MS-PAC cache re-initalization in case of black list change.
Trigger that by asking for cross-realm TGT for HTTP service.
Since FreeIPA KDC supports adding MS-PAC to HTTP/ipa.server principal,
it is possible to use it when talking to the trusted AD DC.
Remove support for authenticating as trust account because it should not
really be used other than within Samba.
Add IPA CLI to manage trust domains.
ipa trust-fetch-domains <trust> -- fetch list of subdomains from AD side and add new ones to IPA
ipa trustdomain-find <trust> -- show all available domains
ipa trustdomain-del <trust> <domain> -- remove domain from IPA view about <trust>
ipa trustdomain-enable <trust> <domain> -- allow users from trusted domain to access resources in IPA
ipa trustdomain-disable <trust> <domain> -- disable access to resources in IPA from trusted domain
By default all discovered trust domains are allowed to access IPA resources
IPA KDC needs also information for authentication paths to subdomains in case they
are not hierarchical under AD forest trust root. This information is managed via capaths
section in krb5.conf. SSSD should be able to generate it once

Make sure that trust-add command fails when admin attempts
to add an Active Directory trust when the realm name and
the domain name of the IPA server do not match.
https://fedorahosted.org/freeipa/ticket/3923
The get_args methods in ipalib.crud and ipalib.plugins.baseldap used
super() calls that skipped some of the classes in the inheritance
chain, and contained code that reimplemented some of the skipped
functionality.
This made it difficult to customize the get_args behavior.
Use proper super() calls.
Some unit tests were failing after ipa-adtrust-install has been run on the
IPA server, due to missing attributes ('ipantsecurityidentifier') and
objectclasses ('ipantuserattrs' and 'ipantgroupattrs'). This patch detects if
ipa-adtrust-install has been run, and adds missing attributes and objectclasses
where appropriate.
https://fedorahosted.org/freeipa/ticket/3852
You cannot re-add the trust and modify the range in the process.
The check in the code was malfunctioning since it assumed that
range_size parameter has default value. However, default value
is assigned only later in the add_range function.

This makes plugin registration easier to read, less error-prone, and,
for many Plugins in a single module, faster to write.
Functionally, the decorator is equivalent to current plugin
registration. However, in the future this style will allow cleaner
semantics.
As an example, and to exercise the new syntax to prevent regressions,
the ping plugin is converted to this style.
Differences in the python byte code fails in a build validation
(rpmdiff) done on difference architecture of the same package.
This patch:
1) Ensures that timestamps of generated *.pyo and *.pyc files match
2) Python integer literals greater or equal 2^32 and lower than 2^64
are converted to long right away to prevent different type of
the integer on architectures with different size of int

Updates old information produced by the ipa help host command.
Also adds a section to ipa-client-install manpage about client

Since krbMaxPwdLife attribute is represented as number of seconds,
setting maxlife to high values such as 999 999 days (~2739 years)
would result to overflow when parsing this attribute in kdb plugin,
and hence default maxlife of 90 days would be applied.
Limit the maximum value of maxlife that can be set through the
framework to 20 000 days (~ 54 years).

Make the interactive prompts interpret the following logic:
- AD range (dom-sid/dom-name set):
require RID base if not set
- local range(dom-sid/dom-name not set):
a) server with adtrust support:
require both RID base and secondary RID base
b) server without adtrust support:
if any of RID base, secondary RID base set,
require both of them
https://fedorahosted.org/freeipa/ticket/3786
One find_entry_by_attr call did not set a search base leading to
LDAP search call with zero search base. This leads to false negative
results from LDAP.
Attempt to resolve SIDs through SSSD first to avoid using trust
account password. This makes possible to run HBAC test requests
without being in 'trusted admins' group.

Adds --range-type option to ipa trust-add command. It takes two
allowed values: 'ipa-ad-trust-posix' and 'ipa-ad-trust'.
When --range-type option is not specified, the range type should be
determined by ID range discovery.
https://fedorahosted.org/freeipa/ticket/3650
Add a new API command 'adtrust_is_enabled', which can be used to determine
whether ipa-adtrust-install has been run on the system. This new command is not
visible in IPA CLI.
Use this command in idrange_add to conditionally require rid-base and
secondary-rid-base options.
Add tests to cover the new functionality
https://fedorahosted.org/freeipa/ticket/3634
When adding a trust, if an id range already exists for this trust,
and options --base-id/--range-size are provided with the trust-add command,
trust-add should fail.
https://fedorahosted.org/freeipa/ticket/3635
Following values of ipaRangeType attribute are supported
and translated accordingly in the idrange commands:
'ipa-local': 'local domain range'
'ipa-ad-winsync': 'Active Directory winsync range'
'ipa-ad-trust': 'Active Directory domain range'
'ipa-ad-trust-posix': 'Active Directory trust range with
POSIX attributes'
'ipa-ipa-trust': 'IPA trust range'
Part of https://fedorahosted.org/freeipa/ticket/3647
In idrange-add command, ensure that RID base is prompted for
in the interactive mode if domain SID or domain name was
specified.
If domain name nor SID was specified, make sure rid base is
prompted for if secondary rid base was specified and vice versa.
https://fedorahosted.org/freeipa/ticket/3602
Extracted common code from ipalib/plugins/cli.py and
ipalib/plugins/dns.py that provided way to prompt user
for the value of specific attribute.
Added prompt_param method to Command class in ipalib/frontend.py
Done as part of https://fedorahosted.org/freeipa/ticket/3602
When removing an ID range using idrange-del command, validation
in pre_callback ensures that the range does not belong to any
active trust. In such case, ValidationError is raised.
Unit tests to cover the functionality has been added.

Prompt for nameserver IP address in interactive mode of dnszone-add.
Add a corresponding field to dnszone creation dialog in the web UI.
This parameter is required if and only if:
* New zone is a forward zone
* Nameserver is defined inside the new zone
Add a new unit test to cover this functionality.
https://fedorahosted.org/freeipa/ticket/3603
Introduce new command, 'trust-resolve', to aid resolving SIDs to names
in the Web UI.
The command uses new SSSD interface, nss_idmap, to resolve actual SIDs.
SSSD caches resolved data so that future requests to resolve same SIDs
are returned from a memory cache.
Web UI code is using Dojo/Deferred to deliver result of SID resolution
out of band. Once resolved names are available, they replace SID values.
Since Web UI only shows ~20 records per page, up to 20 SIDs are resolved
at the same time. They all sent within the single request to the server.

Recent LDAP refactoring replaced entry_attrs regular dict with
normalized keys (i.e. lowercase) with LDAPEntry instance which keys
may not be normalized. This broke CND command output when
--structured and --all options were used.
Force lowercase normalization of the LDAPEntry keys in DNS plugin
structured format postprocessing. Also add a missing test for
DNS record structured output.
https://fedorahosted.org/freeipa/ticket/3526
Following pages were added to Web UI:
* certificated details
* certificate search
Certificate is not regular object so it gets no metadata. Therefore artificial
metadata were created for it to allow usage of search and details facet.
Search and details facet were modified to allow removing of add/remove/update/
reset buttons - certificates have no mod operation and they are not added by
standard means.
User can revoke and restore certificated in details facet.

When adding a duplicate member to a group, an error message is issued,
informing the user that the entry is already a member of the group.
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
group-add-member, but not in group-remove-member.
Unit test file covering these cases was also added.

We catched all errors that could be raised by idrange-add command and
just raised an uncomprehensible ValidationError. This could hide
a real underlying problem and make the debugging harder.
We should rather just let the command raise the real error (which
will be already a PublicError).

This patch adds 'nfs:NONE' as an allowed entry for the global
authorization data type in the CLI and WebUI. This is an ad-hoc solution

When modifing the idrange, one was able to add ipa NT trusted
AD domain sid without objectclass ipatrustedaddomainrange being
added. This patch fixes the issue.
Both now enforce the following checks:
- dom_sid and secondary_rid_base cannot be used together
- rid_base must be used together if dom_rid is set
- secondary_rid_base and rid_base must be used together
if dom_rid is not set
Unit test for third check has been added.

The code split the permission string on commas, essentially doing
poor man's CSV parsing. So if a permission contained a

This is to prevent a fatal name clash wih the new common "messages" Output.
Since i18n_messages is an internal plugin, the change does not affect
our public API.
Several Commands were missing the 'version' option. Add it to those
that were missing it.
Do not remove the version option before calling commands. This means
methods such as execute(), forward(), run() receive it.
Several of these needed `**options` added to their signatures.
Commands in the Cert plugin passed any unknown options to the underlying
functions, these are changed to pass what's needed explicitly.
Some commands in DNS and Batch plugins now pass version to commands
they call.
When the option is not given, fill it in automatically. (In a subsequent
commit, a warning will be added in this case).
Note that the public API did not change: all RPC calls already accepted
a version option. There's no need for an API version bump (even though
API.txt changes substantially).

When user tries to perform any action requiring communication with
trusted domain, IPA server tries to retrieve a trust secret on his
behalf to be able to establish the connection. This happens for
example during group-add-member command when external user is
being resolved in the AD.
When user is not member of Trust admins group, the retrieval crashes
and reports internal error. Catch this exception and rather report
properly formatted ACIError. Also make sure that this exception is
properly processed in group-add-member post callback.

Use a new RESTful API provided by dogtag 10+. Construct an XML document
representing the search request. The output is limited to whatever dogtag
sends us, there is no way to request additional attributes other than
to read each certificate individually.
dogtag uses a boolean for each search term to indicate that it is used.
Presense of the search item is not enough, both need to be set.

Add new LDAP container to store the list of domains associated with IPA realm.
Add two new ipa commands (ipa realmdomains-show and ipa realmdomains-mod) to allow
manipulation of the list of realm domains.
Unit test file covering these new commands was added.
https://fedorahosted.org/freeipa/ticket/2945
When adding/modifying an ID range for a trusted domain, the newly
added option --dom-name can be used. This looks up SID of the
trusted domain in LDAP and therefore the user is not required
to write it down in CLI. If the lookup fails, error message
asking the user to specify the SID manually is shown.
https://fedorahosted.org/freeipa/ticket/3133
Add correct labeling of matched/nonmatched output attributes. Also
make sure that "\" is not interpreted as newline escape character
but really as a "\" character.
How this works:
1. When a trusted domain user is tested, AD GC is searched
for the user entry Distinguished Name
2. The user entry is then read from AD GC and its SID and SIDs
of all its assigned groups (tokenGroups attribute) are retrieved
3. The SIDs are then used to search IPA LDAP database to find
all external groups which have any of these SIDs as external
members
4. All these groups having these groups as direct or indirect
members are added to hbactest allowing it to perform the search
LIMITATIONS:
- only Trusted Admins group members can use this function as it
uses secret for IPA-Trusted domain link
- List of group SIDs does not contain group memberships outside
of the trusted domain
https://fedorahosted.org/freeipa/ticket/2997
When group-add-member does not receive any resolved trusted domain
object SID, it raises an exception which hides any useful error
message passed by underlying resolution methods. Remove the exception
to reveal this error messages to user.
https://fedorahosted.org/freeipa/ticket/2997
Modify access methods to AD GC so that callers can specify a custom
basedn, filter, scope and attribute list, thus allowing it to perform
any LDAP search.
Error checking methodology in these functions was changed, so that it
rather raises an exception with a desription instead of simply returning
a None or False value which would made an investigation why something
does not work much more difficult. External membership method in
group-add-member command was updated to match this approach.
https://fedorahosted.org/freeipa/ticket/2997
Update our LDAP schema and add 2 new attributes for SID blacklist
definition. These new attributes can now be set per-trust with
trustconfig command.
https://fedorahosted.org/freeipa/ticket/3289
Global trust configuration is generated ipa-adtrust-install script
is run. Add convenience commands to show auto-generated options
like SID or GUID or options chosen by user (NetBIOS). Most of these
options are not modifiable via trustconfig-mod command as it would
break current trusts.
Unit test file covering these new commands was added.
https://fedorahosted.org/freeipa/ticket/3333
Add new users to the default users group in batches of 100. The
biggest overhead of migration is in calculating the modlist when
managing the default user's group and applying the changes. A
significant amount of time can be saved by not doing this on every
add operation.
Some other minor improvements include:
Add a negative cache for groups not found in the remote LDAP server.
Replace call to user_mod with a direct LDAP update.
Catch some occurances of LimitError and handle more gracefully.
I also added some debug logging to report on migration status and
performance.
https://fedorahosted.org/freeipa/ticket/3386
Some parts of install scripts used only ccache name as returned by
krbV.CCache.name attribute. However, when this name is used again
to initialize krbV.CCache object or when it is used in KRB5CCNAME
environmental variable, it fails for new DIR type of CCACHE.
We should always use both CCACHE type and name when referring to
them to avoid these crashes. ldap2 backend was also updated to
accept directly krbV.CCache object which contains everything we need
to authenticate with ccache.
https://fedorahosted.org/freeipa/ticket/3381
openldap server does not store its schema in cn=schema entry, but
rather in cn=subschema. Add a fallback to ldap2 plugin to read from
this entry when cn=schema is not found. ldap2 plugin uses the schema
when doing some of the automatic encoding, like an automatic
encoding of DN object.
IPA migration plugin DN attribute processing is now also more
tolerant when it finds that some DN attribute was not autoencoded.
It tries to convert it to DN on its own and report a warning and
continue with user processing when the conversion fails instead of
crashing with AssertionError and thus abandoning the whole
migration run.

forwarders should not be recommended by only be option of last resort.
Fixes https://fedorahosted.org/freeipa/ticket/3261
Web UI part of 'disable global forwaring per zone' effort.
Option "Forwarding disabled" was added to 'DNS global config' and 'DNS zone' forwarding policy. It corresponds to 'none' value of idnsforwardpolicy.
https://fedorahosted.org/freeipa/ticket/3209
bind-dyndb-ldap allows disabling global forwarder per-zone. This may
be useful in a scenario when we do not want requests to delegated
sub-zones (like sub.example.com. in zone example.com.) to be routed
through global forwarder.
Few lines to help added to explain the feature to users too.
https://fedorahosted.org/freeipa/ticket/3209
Nameserver hostname passed to dnszone_add command was always treated
as FQDN even though it was a relative DNS name to the new zone. All
relative names were being rejected as unresolvable.
Modify --name-server option processing in dnszone_add and dnszone_mod
to respect FQDN/relative DNS name and do the checks accordingly. With
this change, user can add a new zone "example.com" and let dnszone_add
to create NS record "ns" in it, when supplied with its IP address. IP
address check is more strict so that it is not entered when no forward
record is created. Places misusing the option were fixed.
Nameserver option now also accepts zone name, which means that NS and A
record is placed to DNS zone itself. Also "@" is accepted as a nameserver
name, BIND understand it also as a zone name. As a side-effect of this
change, other records with hostname part (MX, KX, NS, SRV) accept "@"
as valid hostname. BIND replaces it with respective zone name as well.
Unit tests were updated to test the new format.
https://fedorahosted.org/freeipa/ticket/3204
Since trust-add re-establishes the trust every time it is run and all the other
information fetched from the remote domain controller stays the same, it
can be run multiple times. The only change would occur is update of
trust relationship credentials -- they are supposed to be updated
periodically by underlying infrastructure anyway.
A sequence is following:
1. Match external member against existing trusted domain
2. Find trusted domain's domain controller and preferred GC hosts
3. Fetch trusted domain account auth info
4. Set up ccache in /var/run/ipa_memcached/krb5cc_TD<domain> with principal ourdomain$@trusted.domain
5. Do LDAP SASL interactive bind using the ccache
6. Search for the member's SID
7. Decode SID
8. Replace external member name by SID
Instructions to generate certificate were simplified.
New instructions:
1) Create a certificate database or use an existing one. To create a new database:
# certutil -N -d <database path>
2) Create a CSR with subject CN=<hostname>,O=<realm>, for example:
# certutil -R -d <database path> -a -g <key size> -s 'CN=dev.example.com,O=DEV.EXAMPLE.COM'
3) Copy and paste the CSR (from -----BEGIN NEW CERTIFICATE REQUEST----- to -----END NEW CERTIFICATE REQUEST-----) into the text area below:
