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.

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.
https://fedorahosted.org/freeipa/ticket/2650
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.
https://fedorahosted.org/freeipa/ticket/2606
We need to inform users when a forms-based login fails due to the
password needing to be reset. Currently there is no way to distinguish
a reset case vs an incorrect password.
This will bind the user using a simple LDAP bind over ldapi (by default)
and if that is successful, check the expiration date against the current
time.
The UI portion of this that uses this message will come later.
https://fedorahosted.org/freeipa/ticket/2608
We don't need to do anything with the state but if it exists in
the sysrestore index at the end of uninstallation the uninstaller will
complain about it.
https://fedorahosted.org/freeipa/ticket/2637
certmonger now has the ability to execute a script when it renews a
certificate. This can be used to automatically restart servers so
the certificate doesn't expire in the running server.
https://fedorahosted.org/freeipa/ticket/2050
When IPA server is configured with DNS and its hostname is not
located in a default domain, SRV records are not valid.
Additionally, httpd does not serve XMLRPC interface because it
IPA server domain-realm mapping is missing in krb5.conf. All CLI
commands were then failing.
This patch amends this configuration. It fixes SRV records in
served domain to include full FQDN instead of relative hostname
when the IPA server hostname is not located in served domain.
IPA server forward record is also placed to correct zone.
When IPA server is not in a served domain a proper domain-realm
mapping is configured to krb5.conf. The template was improved
in order to be able to hold this information.

Ticket #2502
* remove the "running" flag from backup_state in cainstance.py and
dsinstance.py because it does not provide the correct
information. In cainstance the running flag was never referenced
because restarting dirsrv instances occurs later in dsinstance. In
dsinstance when the running flag is set it incorrectly identifed the
PKI ds instance configured earlier by cainstance. The intent was to
determine if there were any ds instances other than those owned by
IPA which will need to be restarted upon uninstall. Clearly the PKI
ds instance does not qualify. We were generating a traceback when at
the conclusion of dsinstance.uninstall we tried to start the
remaining ds instances as indicated by the running flag, but there
were none to restart (because the running flag had been set as a
consequence of the PKI ds instance).
* We only want to restart ds instances if there are other ds instances
besides those owned by IPA. We shouldn't be stopping all ds
instances either, but that's going to be covered by another
ticket. The fix for restarting other ds instances at the end of
uninstall is to check and see if there are other ds instances
remaining after we've removed ours, if so we restart them. Also it's
irrelevant if those ds instances were not present when we installed,
it only matters if they exist after we restore things during
uninstall. If they are present we have to start them back up because
we shut them down during uninstall.
* Add new function get_ds_instances() which returns a list of existing
ds instances.
* fixed error messages that incorrectly stated it "failed to restart"
a ds instance when it should be "failed to create".
SELinux configuration for httpd instance was set for new
installations only. Upgraded IPA servers (namely 2.1.x -> 2.2.x
upgrade) missed the configuration. This lead to AVCs when httpd
tries to contact ipa_memcached and user not being able to log in.
This patch updates ipa-upgradeconfig to configure SELinux
in the same way as ipa-server-install does.
https://fedorahosted.org/freeipa/ticket/2603
With a publicly accessible DNS tree in LDAP, anyone with an access
to the LDAP server can get all DNS data as with a zone transfer
which is already restricted with ACL. Making DNS tree not readable
to public is a common security practice and should be applied
in FreeIPA as well.
This patch adds a new deny rule to forbid access to DNS tree to
users or hosts without an appropriate permission or users which
are not members of admins group. The new permission/aci is
applied both for new installs and upgraded servers.
bind-dyndb-ldap plugin is allowed to read DNS tree without any
change because its principal is already a member of "DNS
Servers" privilege.
https://fedorahosted.org/freeipa/ticket/2569
The server installation failed on F17 due to permission problem.
The /var/lib/dirsrv/boot.ldif was previously owned and only readable

When updating from 2.x we need to add nsDS5ReplicatedAttributeList and
nsDS5ReplicatedAttributeListTotal if they aren't present.
If nsDS5ReplicatedAttributeList is present and doesn't contain memberof
then we want to add it.
https://fedorahosted.org/freeipa/ticket/2594
Replace all occurences of create_default with equivalent default_from
and remove create_default from the framework. This is needed for
proper parameter validation, as there is no way to tell which
parameters to validate prior to calling create_default, because
create_default does not provide information about which parameters are
used for generating the default value.
Global DNS configuration is a nice tool to maintain a common DNS
settings stored in LDAP which are then used for all enrolled IPA
servers. However, the settings stored in LDAP override local
settings in named.conf on DNS servers.
This patch adds more information about global DNS configuration
options in install scripts and DNS module help.
https://fedorahosted.org/freeipa/ticket/2525
New features in bind-dyndb-ldap and IPA DNS plugin pulled new
attributes and objectclasses. ACIs and permissions need to be
updated to allow users with appropriate permissions update
these attributes in LDAP.
This patch updates the ACI for DNS record updates and adds one
new permission to update global DNS configuration.

The new version of python-ldap changed the way it created LDAPv3
extended controls. The API used in 2.4.x can no longer be used
because it does not send the bind DN with effective rights
control and LDAP server thus rejects it.
This patch implements the new API in a backward compatible way
so that it works both with python-ldap versions 2.3.x and 2.4.x.
https://fedorahosted.org/freeipa/ticket/2565
get_allowed_attributes function was improved to look for allowed

New version of openldap (openldap-2.4.26-6.fc16.x86_64) changed its
ABI and broke our TLS connection in ipa-replica-manage. This makes
it impossible to connect for example to Active Directory to set up
a winsync replication. We always receive a connection error stating
that Peer's certificate is not recognized even though we pass
a correct certificate.
This patch fixes the way we set up TLS. The change is backwards
compatible with older versions of openldap.

When a replica is deleted, its memberPrincipal entries in
cn=s4u2proxy,cn=etc,SUFFIX were not removed. Then, if the replica
is reinstalled and connected again, the installer would report
an error with duplicate value in LDAP.
This patch extends replica cleanup procedure to remove replica
principal from s4u2proxy configuration.
https://fedorahosted.org/freeipa/ticket/2451
A number of different errors could occur when trying to handle an
error which just confused matters.
If no CCache was received then trying to retrieve context.principal
in the error message caused yet another exception to be raised.
Trying to get Command[name] if name wasn't defined in command would
raise an exception.
Trying to raise errors.CCache was failing because the response hadn't
been started.

Our install tools like ipa-server-install, ipa-replica-{prepare,
install} may allow hostnames that do not match the requirements
in ipalib. This creates a disconnect and may cause issues when
user cannot delete hostnames created by install tools.
This patch makes sure that ipalib requirements are applied to
install tools hostnames as well.
https://fedorahosted.org/freeipa/ticket/2089
We don't want to run the risk of adding a user, uninstalling it,
the system adding a new user (for another package install for example)
and then re-installing IPA. This wreaks havoc with file and directory
ownership.

login_password is expecting that request content_type will be 'application/x-www-form-urlencoded'.
Current check is an equality check of content_type http header.
RFC 3875 defines that content type can contain parameters separated by ';'. For example: when firefox is doing ajax call it sets the request header to 'application/x-www-form-urlencoded; charset=UTF-8' which leads to negative result.
This patch makes the check more benevolent to allow such values.
Patch is a fixup for:
https://fedorahosted.org/freeipa/ticket/2095
* Adjust URL's
- rename /ipa/login -> /ipa/session/login_kerberos
- add /ipa/session/login_password
* Adjust Kerberos protection on URL's in ipa.conf
* Bump VERSION in httpd ipa.conf to pick up session changes.
* Adjust login URL in ipa.js
* Add InvalidSessionPassword to errors.py
* Rename krblogin class to login_kerberos for consistency with
new login_password class
* Implement login_password.kinit() method which invokes
/usr/bin/kinit as a subprocess
* Add login_password class for WSGI dispatch, accepts POST
application/x-www-form-urlencoded user & password
parameters. We form the Kerberos principal from the server's
realm.
* Add function krb5_unparse_ccache()
* Refactor code to share common code
* Clean up use of ccache names, be consistent
* Replace read_krbccache_file(), store_krbccache_file(), delete_krbccache_file()
with load_ccache_data(), bind_ipa_ccache(), release_ipa_ccache().
bind_ipa_ccache() now sets environment KRB5CCNAME variable.
release_ipa_ccache() now clears environment KRB5CCNAME variable.
* ccache names should now support any ccache storage scheme,
not just FILE based ccaches
* Add utilies to return HTTP status from wsgi handlers,
use constants for HTTP status code for consistency.
Use utilies for returning from wsgi handlers rather than
duplicated code.
* Add KerberosSession.finalize_kerberos_acquisition() method
so different login handlers can share common code.
* add Requires: krb5-workstation to server (server now calls kinit)
* Fix test_rpcserver.py to use new dispatch inside route() method
https://fedorahosted.org/freeipa/ticket/2095
Previously sessions expired after session_auth_duration had elapsed
commencing from the start of the session. We new support a "rolling"
expiration where the expiration is advanced by session_auth_duration
everytime the session is accessed, this is equivalent to a inactivity
timeout. The expiration is still constrained by the credential
expiration in all cases. The session expiration behavior is
configurable based on the session_auth_duration_type.
* Reduced the default session_auth_duration from 1 hour to 20 minutes.
* Replaced the sesssion write_timestamp with the access_timestamp and
update the access_timestamp whenever the session data is created,
retrieved, or written.
* Modify set_session_expiration_time to handle both an inactivity
timeout and a fixed duration.
* Introduce KerberosSession as a mixin class to share session
duration functionality with all classes manipulating session data
with Kerberos auth. This is both the non-RPC login class and the RPC
classes.
* Update make-lint to handle new classes.
* Added session_auth_duration_type config item.
* Updated default.conf.5 man page for new session_auth_duration_type item.
* Removed these unused config items: mount_xmlserver,
mount_jsonserver, webui_assets_dir
https://fedorahosted.org/freeipa/ticket/2392
* Increase the session ID from 48 random bits to 128.
* Implement the sesison_logout RPC command. It permits the UI to send
a command that destroys the users credentials in the current
session.
* Restores the original web URL's and their authentication
protections. Adds a new URL for sessions /ipa/session/json. Restores
the original Kerberos auth which was for /ipa and everything
below. New /ipa/session/json URL is treated as an exception and
turns all authenticaion off. Similar to how /ipa/ui is handled.
* Refactor the RPC handlers in rpcserver.py such that there is one
handler per URL, specifically one handler per RPC and AuthMechanism
combination.
* Reworked how the URL names are used to map a URL to a
handler. Previously it only permitted one level in the URL path
hierarchy. We now dispatch on more that one URL path component.
* Renames the api.Backend.session object to wsgi_dispatch. The use of
the name session was historical and is now confusing since we've
implemented sessions in a different location than the
api.Backend.session object, which is really a WSGI dispatcher, hence
the new name wsgi_dispatch.
* Bullet-proof the setting of the KRB5CCNAME environment
variable. ldap2.connect already sets it via the create_context()
call but just in case that's not called or not called early enough
(we now have other things besides ldap which need the ccache) we
explicitly set it early as soon as we know it.
* Rework how we test for credential validity and expiration. The
previous code did not work with s4u2proxy because it assumed the
existance of a TGT. Now we first try ldap credentials and if we
can't find those fallback to the TGT. This logic was moved to the
KRB5_CCache object, it's an imperfect location for it but it's the
only location that makes sense at the moment given some of the
current code limitations. The new methods are KRB5_CCache.valid()
and KRB5_CCache.endtime().
* Add two new classes to session.py AuthManager and
SessionAuthManager. Their purpose is to emit authication events to
interested listeners. At the moment the logout event is the only
event, but the framework should support other events as they arise.
* Add BuildRequires python-memcached to freeipa.spec.in
* Removed the marshaled_dispatch method, it was cruft, no longer
referenced.

ipautil.run expects a tuple of passwords for nolog; passing a
single string causes all individual letters from that string to
be replaced by Xes.
This fixes such a call, and adds a sanity check to ipautil.run
that prevents lone strings from being used in nolog.

SSH public key support includes a feature to automatically add/update
client SSH fingerprints in SSHFP records. However, the update won't
work for zones created before this support was added as they don't
allow clients to update SSHFP records in their update policies.
This patch lets dns upgrade module extend the original policy
to allow the SSHFP dynamic updates. It updates only original
policy, we don't want it to overwrite custom user policies.

force-sync, re-initialize and del were not working because they
all attempted to contact the AD server. winsync agreements are
managed on the local 389-ds instance.
This also:
- requires root to create winsync agreement (for updating NSS db)
- fixes filter in get_replication_agreement() to work with winsync
https://fedorahosted.org/freeipa/ticket/2128
Provide a way to specify BIND allow-query and allow-transfer ACLs
for DNS zones.
IMPORTANT: new bind-dyndb-ldap adds a zone transfer ability. To
avoid zone information leaks to unintended places, allow-transfer
ACL for every zone is by default set to none and has to be
explicitly enabled by an Administrator. This is done both for new
DNS zones and old DNS zones during RPM update via new DNS upgrade
plugin.
https://fedorahosted.org/freeipa/ticket/1211
Implement API for DNS global options supported in bind-dyndb-ldap.
Currently, global DNS option overrides any relevant option in
named.conf. Thus they are not filled by default they are left as
a possibility for a user.
Bool encoding had to be fixed so that Bool LDAP attribute can also
be deleted and not just set to True or False.
