0e3d064ac1 restart dirsrv as part of ipa-adtrust-install
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

54135ecd9a Store session cookie in ccache for cli users
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.

d1e695b5d0 Password change capability for form-based auth
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

34a1dee934 Only set sebools when necessary
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.

1d44aba89b Enable psearch on upgrades
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.

c856fb6073 Add sysupgrade state file
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.

6f1baf8b16 Only allow root to run update plugins
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.

0ca29fac9a Move install script error handling to a common function
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.

f1ed123cad Replace DNS client based on acutil with python-dns
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

6bb462e26a Retry retrieving ldap principals when setting up replication.
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.

aa9ea477af Remove ipa-server-install LDAP update errors
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.

f19218f7d8 Remove duplicate and unused utility code
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.

a663e83cb2 Raise proper exception when LDAP limits are exceeded
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.

184a066f4a Fix installation when server hostname is not in a default domain
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.

af0ac845ff improve handling of ds instances during uninstall
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".

df13cdcb97 Forbid public access to DNS tree
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
