When connecting to replica, ipa-replica-manage could fail with
unknown error due to connection time out. This patch properly
handles the situation
Fixed in conjunction with https://fedorahosted.org/freeipa/ticket/3524
In ipa-replica-manage commands, we enforce that hostnames we work
with are resolvable. However, this caused errors while deleting
or disconnecting a ipa / winsync replica, if that replica was down
and authoritative server for itself.
Also adds an --no-lookup flag to disable host existence checks.
https://fedorahosted.org/freeipa/ticket/3524
Trying to insert nsDS5ReplicatedAttributeListTotal and
nsds5ReplicaStripAttrs to winsync agreements caused upgrade errors.
With this patch, these attributes are skipped for winsync agreements.
Made find_ipa_replication_agreements() in replication.py more
corresponding to find_replication_agreements. It returns list of
entries instead of unicode strings now.
https://fedorahosted.org/freeipa/ticket/3522
If you break a replica install after the agreement is created but
before it gets much further you'll be in the situation where an
agreement exists, no cn=masters entry exists, and the RUV may not
be set yet.
This adds some error handling so the broken install can be safely
removed.

Attempt to automatically save DNA ranges when a master is removed.
This is done by trying to find a master that does not yet define
a DNA on-deck range. If one can be found then the range on the deleted
master is added.
If one cannot be found then it is reported as an error.
Some validation of the ranges are done to ensure that they do overlap
an IPA local range and do not overlap existing DNA ranges configured
on other masters.

The find_entries method is cumbersome to use: it requires keyword arguments
for simple uses, and callers are tempted to ignore the 'truncated' flag
it returns.
Introduce a simpler method, get_entries, that returns the found
list directly, and raises an errors if the list is truncated.
Replace the getList method by get_entries.
Part of the work for: https://fedorahosted.org/freeipa/ticket/2660
Change the discovery code to validate all servers, regardless of where
the originated (either via SRV records or --server). This will prevent
the client installer from failing if one of those records points to a
server that is either not running or is not an IPA server.
If a server is not available it is not removed from the list of configured
servers, simply moved to the end of the list.
If a server is not an IPA server it is removed.

When deleting a replica from IPA domain:
* Abort if the installation is about to be left without CA
* Warn if the installation is about to be left without DNS
Ticket: https://fedorahosted.org/freeipa/ticket/2879
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
When executing ipa-replica-manage connect to an master that raises
NotFound error we now check if the master is at least IPA server.
If so, we inform the user that it is probably foreign or previously
deleted master. If not, we inform the user that the master is not
an IPA server at all.
https://fedorahosted.org/freeipa/ticket/3105
Correctly handle case where we bind using GSSAPI with an unauthorized user.
Remove extraneous except clause. We now have handle for LDAP errors.
Make it explicit in a few places what server we can't connect to.
When the remote replica is down and we are forcing its removal, remove
a duplicate entry from the list of servers to remove.
https://fedorahosted.org/freeipa/ticket/2871
If you have a replication topology like A <-> B <-> C and you try
to delete server B that will leave A and C orphaned. It may also
prevent re-installation of a new master on B because the cn=masters
entry for it probably still exists on at least one of the other masters.
Check on each master that it connects to to ensure that it isn't the
last link, and fail if it is. If any of the masters are not up then
warn that this could be a bad thing but let the user continue if
they want.
Add a new option to the del command, --cleanup, which runs the
replica_cleanup() routine to completely clean up references to a master.
https://fedorahosted.org/freeipa/ticket/2797
This adds two new commands to ipa-replica-manage: list-ruv & clean-ruv
list-ruv can be use to list the update vectors the master has
configugured
clean-ruv can be used to fire off the CLEANRUV task to remove a
replication vector. It should be used with caution.
https://fedorahosted.org/freeipa/ticket/2303
Due to recent addition of ID range support to DsInstance, the class
could no longer be instantiated when realm_name was passed but
ID range parameters were not. This condition broke winsync agreements
creation in ipa-replica-manage.
Make sure that ID range computation in DsInstance does not crash in
this cases so that winsync replica can be created. Also convert --binddn
option of ipa-replica-manage script to IPA native DN type so that
setup_agreement does not crash.
https://fedorahosted.org/freeipa/ticket/2987
* 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.

When setting up agreements we need to be careful in not allowing to
'reconnect' a master that was previously completely deleted as it would
misses entries that are vital for proper functioning. This change in code
fixes 2 problems with the current approach.
1) it removes false positives when we are tryig to reconnect a replica that
was previosuly merely disconnected but was still part of the domain and just
replicating via a different topology and not a direct link
2) adds checks for entries that are deleted when an actual removal is
performed. so that we cannot 'reconnect' previously unrelated replicas when
one of the 2 has been permanently deleted from the masters tree.
Second part of ticket https://fedorahosted.org/freeipa/ticket/2925
This is just a typo, we were checking one side twice and never the other
side. So depending on which side you run the command you'd be able or not
to remove the replication agreement even if it was the last one.
First part of ticket: https://fedorahosted.org/freeipa/ticket/2925
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
Using ipa-replica-manage del <replica> is irreversible. You can't
turn around and do a connect to it, all heck will break loose. This is
because we clean up all references to the replica when we delete so if
we connect to it again we'll end up deleting all of its principals.
When a connection is deleted then the agreement is removed on both sides.
What isn't removed is the nsDS5ReplicaBindDN so we can use that to
determine if we previously had a connection.
https://fedorahosted.org/freeipa/ticket/2126
memberof is not in the EXCLUDE list of nsDS5ReplicatedAttributeListTotal
so we have no need of running the task, memberof will come with the
data.
If that attribute doesn't exist then this agreement was created with
an older version of 389-ds, we DO need to initialize memberOf.
https://fedorahosted.org/freeipa/ticket/2199
We currently only support a single winsync agreement so all we need
to do is check to see if we have one with the remote host.
This also adds some minor exception handling cleanup.
https://fedorahosted.org/freeipa/ticket/2130
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
When using ipa-replica-manage or ipa-csreplica-manage to delete an
agreement with a host we would try to make a connection to that host
prior to tryign to delete it. This meant that the trying to delete
a host we don't have an agreement with would return a connection
error instead of a "no agreement with host foo" error.
Also display a completed message when an agreement is removed.
https://fedorahosted.org/freeipa/ticket/2048https://fedorahosted.org/freeipa/ticket/2125
change default_logger_level to debug in configure_standard_logging
add new ipa_log_manager module, move log_mgr there, also export
root_logger from log_mgr.
change all log_manager imports to ipa_log_manager and change
log_manager.root_logger to root_logger.
add missing import for parse_log_level()
When getpass.getpass() function is interrupted via CTRL+D, EOFError
exception is thrown. Most of the install tools are not prepared for
this event and crash with this exception. Make sure that it is
handled properly and nice error message is printed.
https://fedorahosted.org/freeipa/ticket/1916
Logging errors are printed out when ipa-replica-manage is run
as a non-root user. Log has been disabled in such case to
prevent such messages.
https://fedorahosted.org/freeipa/ticket/1046
By calling directly sasl_interactive_bind_s() we were not calling __lateinit()
This in turn resulted in some variables like dbdir not to be set on the
IPAadmin object.
Keep all bind types in the same place so the same common sbind steps can be
performed in each case.
