check_ldap_conf is only available in FreeIPA 4.7 and later and
tasks.is_nosssd_supported is only available since 4.6.90.pre2.

check_ldap_conf is None (ansible_ipa_client) if it can not be imported.
hasattr has been added to check if is_nosssd_supported is a valid
attribute in tasks.

Fixes: #61 (ipaserver role - Fails on ipaclient install)

The entity argument for validate_domain_name is only available in
FreeIPA 4.7 and later. This has been fixed using inspect to be able to
detect if entity is a valid argument. If not the whole realm name check
is skipped.

Fixes: #66 (Python 2 error with validate_domain)

ipaserver_test was not handling possible exceptions in the tests which
resulted in a traceback. This has been fixed.

This setting had the wrong and unsed prefix ipahost. THis has been fixed and
the proper prefix ipaclient is now used.

The change in ipaclient/defaults/main.yml was missing from the first commit
b5d6dc00

These test are failing because there is no adtrust_imported and
kra_imported setting yet in ansible_ipa_replica.

If replica_conn_check failed a back trace was printed instead of a proper
failure in ansible. Thias has been fixed.

The configuration of DNS failed because of missing DNS settings in the
ipareplica_prepare and ipareplica_setup_dns.

Some fixed settings for use with DNSInstallInterface have been added
to ansible_ipa_replica:

options.dnssec_master = False
options.disable_dnssec_master = False
options.kasp_db_file = None
options.force = False

Fixes: #58 (install-replica fails: reverse_zones seems to be empty)
Fixes: #63 (ipareplica_setup_dns fails)

Removed unused user_input import from ipapython.ipautil. Added import
of DN from ipapython.dn. Set ntpinstance to None if timeconf or
sync_time could not be imported on older FreeIPA releases.

Use ipaserver_install_packages to enable or disable package installation
for the client deployment part with ipaclient role.

Use ipareplica_install_packages to enable or disable package installation

Replica config is not needed and there fore has been removed.

The dns settings in options have not been used and also not provided to
the module in the tasks file. Therefore these settings shoul dbe removed.

ipaserver_master_password and ipaserver_setup_ntp have been linked from
the ipaserver role before. With the move of the module_utils parts to the
specific role locations the use of ipaserver modules leads to the missing
dependency ansible_ipa_server, that is now only available in the server
role.

The ipaserver_master_password module has been replaced by the ipareplica
specific ipareplica_master_password module. The ipaserver_setup_ntp module
has been removed as the time related changes for replica are done in the
client install part.

Fixes: #59 (Module is missing interpreter line)

The installer logs have not been created using the ansible ipaclient,
ipareplica and ipaserver roles. This has been fixed and the installer
logs are created now.

This setting had the wrong and unsed prefix ipahost. THis has been fixed and
the proper prefix ipaclient is now used.

Krb5 configuration was also done if ipaclient_on_master was set. This
resulted in a reverted configuration while deploying the client part in
a server deploment.

The role test is executed in the ipa[server,replica,client] roles first.
These tests are usable in the Ansible test mode, but the folllowing steps
in the task list are not. Therefore the blocks following the tests are
limited to not being executed in test mode.

python_2_3_test needs to be executed also in test mode to make sure that the
follwing ipa[server,replica,client]_test modules could be executed also in
test mode.

The changed flag is not set to True any more to make sure that the try
to deploy an already deployed server again will not result in an error.

Up to now the try to deploy an already deployed replica resulted in an
error. Now this ends in an end play and no error is reported.

For consitency the result_ prefix has been added to the registered result
of the py3test.py script.

With the changes for IPA enablement in the replica installer it is not
possible anymore to enable the IPA server in the same way as in the
server deployment.

The new module ipareplica_enable_ipa has been added and the link for
ipaserver_enable_ipa has been removed.

The parameter config_setup_ca has been renamed to setup_ca and added to
options. master_host_name has been added to config. Also a call for
api.Backend.ldap2.connect has been added to make sure that the backend is
connected.

The promote argument has been dropped with the final removal of domain
level 0 support in version 4.7.1. The fstore argument has been added
with the 4.7.1 version also.

The promote argument has been dropped with the final removal of domain
level 0 support in version 4.7.1. The fstore argument has been added
with the 4.7.1 version also.

Double imports and also the import of create_replica_config from
ipaserver.install.installutils have been removed. create_replica_config
is not used because the use of domain level 0 is not supported.

ntp_server and ntp_pool are now provided to ipareplica_test. A conflict
test with no_ntp has been added from the normal installer.

Also added are references to options.password and options.dm_password, but
these are commented out and not used or provided to the module.

Proper ntp_servers and ntp_pool tests are needed still.

With FreeIPA 4.7.0 there is no support for domain level 0 anymore, the
check for the minimal domain level should use MIN_DOMAIN_LEVEL instead of
DOMAIN_LEVEL_1.

Since FreeIPA version 4.7.1 there is no install_check defined anymore in
ipaserver.install.server.replicainstall.

The use of ScriptError without an error message but with rval resulted in
very limited information in ansible. The error messages from logger.error
calls have have added to these ScriptError raises.

Removed addtional empty line in ipaclient_setup_sssd sectio

default(omit) is not needed for bool values, as these need to be set either
way.

The __getattr__ method in installer_obj was used for debugging to make
sure that all needed settings in the installer object have been set.

A remain from debugging in ipaclient_test has been removed.

Deploying a client with one-time password use was failing in latest tests
using ansible 2.7 and FreeIPA 4.7 because of an encoding problem.

If the client is already installed and the allow_repair and force_join
options are not set end the playbook processing. This is useful if an
inventory file contains existing and new machines.

The advantage of this is that the krb5 configuration is created in the same
way as in the normal installers. The same functionality as in the normal
installers is used in ipaclient_setup_krb5. There is no need to adapt the
ipa-krb5 role or the the ask file for changes in how the krb5 configuration
is done. Additionally ipaclient_force is now a supported parameter as
it is in the normal installer.

New config option:

ipaclient_force

The variable has been added to ipaclient/defaults/main.yml.
