When setting up AD trusts support, ipa-adtrust-install utility
needs to be run as:
- root, for performing Samba configuration and using LDAPI/autobind
- kinit-ed IPA admin user, to ensure proper ACIs are granted to
fetch keytab
As result, we can get rid of Directory Manager credentials in ipa-adtrust-install

Certificate renewal can be done only one one CA as the certificates need
to be shared amongst them. certmonger has been trained to communicate
directly with dogtag to perform the renewals. The initial CA installation
is the defacto certificate renewal master.
A copy of the certificate is stored in the IPA LDAP tree in
cn=ca_renewal,cn=ipa,cn=etc,$SUFFIX, the rdn being the nickname of the
certificate, when a certificate is renewed. Only the most current
certificate is stored. It is valid to have no certificates there, it means
that no renewals have taken place.
The clones are configured with a new certmonger CA type that polls this
location in the IPA tree looking for an updated certificate. If one is
not found then certmonger is put into the CA_WORKING state and will poll
every 8 hours until an updated certificate is available.
The RA agent certificate, ipaCert in /etc/httpd/alias, is a special case.
When this certificate is updated we also need to update its entry in
the dogtag tree, adding the updated certificate and telling dogtag which
certificate to use. This is the certificate that lets IPA issue
certificates.
On upgrades we check to see if the certificate tracking is already in
place. If not then we need to determine if this is the master that will
do the renewals or not. This decision is made based on whether it was
the first master installed. It is concievable that this master is no
longer available meaning that none are actually tracking renewal. We
will need to document this.

There are two problems in task naming in LDAP updates:
1. Randomness may be scarce in virtual machines
2. Random number is added to the time value rounded to a second
The second issue leads to values that may repeat themselves as time
only grows and random number is non-negative as well, so
t2+r2 can be equal to t1+t2 generated earlier.
Since task name is a DN, there is no strict requirement to use an integer value.
Instead, we generate an UUID and use its 60-bit time, 14-bit sequential number,
and attribute name.

Currently, FreeIPA's install/admin scripts are long pieces of code
that aren't very reusable, importable, or testable.
They have been extended over time with features such as logging and
error handling, but since each tool was extended individually, there
is much inconsistency and code duplication.
This patch starts a framework which the admin tools can use, and
converts ipa-ldap-updater to use the framework.
Common tasks the tools do -- option parsing, validation, logging
setup, error handling -- are represented as methods. Individual
tools can extend, override or reuse the defaults as they see fit.
The ipa-ldap-updater has two modes (normal and --upgrade) that
don't share much functionality. They are represented by separate
classes. Option parsing, and selecting which class to run, happens
before they're instantiated.
All code is moved to importable modules to aid future testing. The
only thing that remains in the ipa-ldap-updater script is a two-line
call to the library.
First part of the work for:
https://fedorahosted.org/freeipa/ticket/2652
Realm administrator account may be specified using different form:
Administrator, DOM\Administrator, Administrator@DOMAIN
This patch introduces handling of the second two forms:
- In DOM\Administrator only user name is used, short domain name
is then taken from a discovered record from the AD DC
- In Administrator@DOMAIN first DOMAIN is verified to be the same
as the domain we are establishing trust to, and then user name
is taken, together with short domain name taken from a discovered
record from the AD DC
Note that we do not support using to-be-trusted domain's trusted domains'
accounts to establish trust as there is basically zero chance to verify
that things will work with them. In addition, in order to establish trust
one needs to belong to Enterprise Admins group in AD or have specially
delegated permissions. These permissions are unlikely delegated to the
ones in already trusted domain.
https://fedorahosted.org/freeipa/ticket/2864
IPA 3.0 introduced range ID objects in replicated space which specify
a range of IDs assigned via DNA plugin. ipa-ldap-updater generates the
default ID range which should correspond with IDs assigned to IPA
users.
However, since correct range size is not known, we should at least
warn that a range with invalid size was created so that user can
amend it.
https://fedorahosted.org/freeipa/ticket/2892
SOA serial autoincrement is a requirement for major DNS features,
e.g. zone transfers or DNSSEC. Enable it by default in named.conf
both for new and upgraded installations. Name of the bind-dyndb-ldap
option is "serial_autoincrement".
From now on, idnsSOAserial attribute also has to be put to
replication agreement exclude list as serial will be incremented
on each DNS server separately and won't be shared. Exclude list
has to be updated both for new replication agreements and the
current ones.
Minimum number of connections for bind-dyndb-ldap has been rised
to 4 connections, the setting will be updated during package upgrade.
https://fedorahosted.org/freeipa/ticket/2554
Many functions use low-level socket interface for connection or
various checks. However, most of the time we don't respect
automatic address family detection but rather try to force our
values. This may cause either redundat connection tries when an
address family is disabled on system tries or even crashes
when socket exceptions are not properly caught.
Instead of forcing address families to socket, rather use
getaddrinfo interface to automatically retrieve a list of all
relevant address families and other connection settings when
connecting to remote/local machine or binding to a local port.
Now, we will also fill correctly all connection parameters like
flowinfo and scopeid for IPv6 connections which will for example
prevent issues with scoped IPv6 addresses.
bind_port_responder function was changed to at first try to bind
to IPv6 wildcard address before IPv4 as IPv6 socket is able to
accept both IPv4 and IPv6 connections (unlike IPv4 socket).
nsslib connection was refactored to use nss.io.AddrInfo class to
get all the available connections. Socket is now not created by
default in NSSConnection class initializer, but rather when the
actual connection is being made, becase we do not an address family
where connection is successful.

All service start/restart currently go through ipapython/platform so
move the "wait for service to start" code there as well.
A dictionary of known services and ports to wait on is defined in base.py
This is referenced by the platforms by instance name to determine what
to wait for. For the case of dirsrv if we get that as a plain name
(no specific instance) it is assumed to be the main IPA service.

Create default range both on new install and on upgrades. Also make
sure that all range object classes are present for upgraded machines.
Default range LDIF entry for new install was fixed so that new
installation does not crash.
https://fedorahosted.org/freeipa/ticket/2891
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.
https://fedorahosted.org/freeipa/ticket/2664
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

This extop can be used by clients of the IPA domain, e.g. sssd, to
retrieve data from trusted external domains. It can be used e.g. to map
Windows SIDs to user or groups names and back.
A postop plugin is added to create the SID for new created users and
groups. A directory server task allows to set the SID for existing
users and groups.
Fixes https://fedorahosted.org/freeipa/ticket/2825
We should restart Directory Server when performing AD trusts configuration
to enable new CLDAP plugin and force KDC to notice MS PAC is now available.
Previously we only restarted KDC but if dirsrv is restarted, KDC will notice
its socket disappeared and will refresh itself

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
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

setsebool -P was run for every package upgrade or server
installation even though the sebools were already set to the new
value.
Only set sebools which are different from current system values.
This speeds up ipa-upgradeconfig or package update by 150 seconds.
From IPA 3.0, persistent search is a preferred mechanism for new DNS
zone detection and is also needed for other features (DNSSEC, SOA
serial updates).
Enable psearch and make sure connections attribute is right. This
step is done just once for a case when user switched the persistent
search back to disabled on purpose.
ipa-upgradeconfig was updated to accept --debug option in case
somebody would want to see debug messages.
From IPA version 3.0, the persistent search is a preferred mechanism
to for DNS zone list management. It will be also a requirement for
several bind-dyndb-ldap features, like SOA serial automatic updates
or DNSSEC.
Make this mechanism default in ipa-server-install and ipa-dns-istall.
https://fedorahosted.org/freeipa/ticket/2524
When IPA package is being updated, some of the configuration files
are also updated. Sometimes it may be useful to store upgrade meta
information for next package upgrades. For example an information
that some config file was already updated and we don't want to
update it again if user purposedly reverted the change.
This patch adds a new StateFile in /var/lib/ipa/sysupgrade which
is capable of holding this information. New sysupgrade.py module
was created to provide simple API to access the upgrade state
information.
Sort a filtered list in the update plugin ordering method.
Unlike the previous algorithm, this always gives a correct order.
It should also be faster and more readable.
https://fedorahosted.org/freeipa/ticket/2820
Several plugins need restarting the DS (or they currently do
an external bind).
Rather than disabling plugins (possibly partially), refuse
to run them when run as an unprivileged user.
This means running ipa-ldap-updater as non-root requires specifying
a list of files, and omiting the --upgrade and --plugins options.
https://fedorahosted.org/freeipa/ticket/2621
Also make sure all exceptions are captured when creating CIFS service
record. The one we care about is duplicate entry and we do nothing
in that case anyway.
Also make uniform use of action descriptors.
We want to always resolve TGS requests even if the user mistakenly sends a
request for a service ticket where the fqdn part contain upper case letters.
The actual implementation follows hints set by KDC. When AP_REQ is done, KDC
sets KRB5_FLAG_ALIAS_OK and we obey it when looking for principals on TGS requests.
https://fedorahosted.org/freeipa/ticket/1577
Samba just needs the cifs/ key on the ipa server. Configure samba to use a
different keytab file so that we do not risk samba commands (net, or similar)
to mess up the system keytab.
https://fedorahosted.org/freeipa/ticket/2168
We need two attributes in the ipaNTTrustedDomain objectclass to store different
kind of SID. Currently ipaNTSecurityIdentifier is used to store the Domain-SID
of the trusted domain. A second attribute is needed to store the SID for the
trusted domain user. Since it cannot be derived safely from other values and
since it does not make sense to create a separate object for the user a new
attribute is needed.
https://fedorahosted.org/freeipa/ticket/2191
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.
https://fedorahosted.org/freeipa/ticket/2441
All of our install/admin scripts had a try/except block calling the
main function and handling common exceptions. These were copy-pasted
from each other and modified to various levels of sophistication.
This refactors them out of installers to a single function, which
includes a final pass/fail message for all of the scripts.
Non-install scripts that set up the same log handler levels for
stderr and log file are not changed, as it's not possible to log
to only the logfile without changing the logger configuration.
https://fedorahosted.org/freeipa/ticket/2071
IPA client and server tool set used authconfig acutil module to
for client DNS operations. This is not optimal DNS interface for
several reasons:
- does not provide native Python object oriented interface
but but rather C-like interface based on functions and
structures which is not easy to use and extend
- acutil is not meant to be used by third parties besides
authconfig and thus can break without notice
Replace the acutil with python-dns package which has a feature rich
interface for dealing with all different aspects of DNS including
DNSSEC. The main target of this patch is to replace all uses of
acutil DNS library with a use python-dns. In most cases, even
though the larger parts of the code are changed, the actual
functionality is changed only in the following cases:
- redundant DNS checks were removed from verify_fqdn function
in installutils to make the whole DNS check simpler and
less error-prone. Logging was improves for the remaining
checks
- improved logging for ipa-client-install DNS discovery

We've seen on a few occassions where one side or the other is missing
the ldap principal. This causes replication to fail when trying to
convert to using GSSAPI. If this happens force a synchronization again
and try the retrieval again, up to 10 times.
This should also make the error report clearer if even after the retries
one of the principals doesn't exist.
https://fedorahosted.org/freeipa/ticket/2737
bind-dyndb-ldap persistent search queries LDAP for all DNS records.
The LDAP connection must have no size or time limits to work
properly.
This patch updates limits both for existing service principal
on updated machine and for new service principals added
as a part of DNS installation.
https://fedorahosted.org/freeipa/ticket/2531
python-ldap add_s method raises a NO_SUCH_OBJECT exception when
a parent entry of the entry being added does not exist. This may
not be an error, for example NIS entries are only added when NIS
is enabled and thus the NIS entry container exists.
The exception raised by python-ldap is also incorrectly processed
in ipaldap's addEntry function and an irrelevant exception is
re-raised instead.
Fix LDAP updater to just log an information when an object cannot
be added due to missing parent object. Also make sure that the
addEntry function exception processing provides the right exception
with a useful description.

IPA has some unused code from abandoned features (Radius, ipa 1.x user
input, commant-line tab completion), as well as some duplicate utilities.
This patch cleans up the utility modules.
Duplicate code consolidated into ipapython.ipautil:
{ipalib.util,ipaserver.ipautil,ipapython.ipautil}.realm_to_suffix
{ipaserver,ipapython}.ipautil.CIDict
(with style improvements from the ipaserver version)
{ipapython.entity,ipaserver.ipautil}.utf8_encode_value
{ipapython.entity,ipaserver.ipautil}.utf8_encode_values
ipalib.util.get_fqdn was removed in favor of the same function in
ipaserver.install.installutils
Removed unused code:
ipalib.util:
load_plugins_in_dir
import_plugins_subpackage
make_repr (was imported but unused; also removed from tests)
ipapython.ipautil:
format_list
parse_key_value_pairs
read_pairs_file
read_items_file
user_input_plain
AttributeValueCompleter
ItemCompleter
ipaserver.ipautil:
get_gsserror (a different version exists in ipapython.ipautil)
ipaserver.ipautil ended up empty and is removed entirely.

Move the code for encoding boolean values to LDAP boolean syntax from the
Parameter class to the Encoder class, where the rest of LDAP encoding takes
place. Remove encoding code from the Parameter class altogether, as all LDAP
encoding should be done in the Encoder class.
This reverts commit a58cbb985e.
We are going to take another approach to this. Instead of erroring
out on attributes that don't seem to be allowed we are going to
eventually return a warning.
ldap2 plugin returns NotFound error for find_entries/get_entry
queries when the server did not manage to return an entry
due to time limits. This may be confusing for user when the
entry he searches actually exists.
This patch fixes the behavior in ldap2 plugin to
1) Return even a zero search results + truncated bool set in
ldap2.find_entries
2) Raise LimitsExceeded in ldap2.get_entry and
ldap2.find_entry_by_attr instead of NotFound error
This changed several assumptions about ldap2.find_entries
results. Several calls accross IPA code base had to be
amended.
