Issue

The check in check_client_configuration is no longer compatible with systems that don't have a global FreeIPA installation in /etc/ipa but a local configuration in IPA_CONFDIR env var.

Steps to Reproduce

• Create ~/.ipa/default.conf
• $ IPA_CONFDIR=~/.ipa python3 -m ipaclient

>>> from ipalib import api
>>> from ipalib import util
>>> import os
>>> api.bootstrap(confdir=os.path.expanduser("~/.ipa"))
>>> util.check_client_configuration(api.env)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/heimes/redhat/freeipa/ipalib/util.py", line 1160, in check_client_configuration
    2)  # CLIENT_NOT_CONFIGURED
ipapython.admintool.ScriptError: IPA client is not configured on this system
>>> os.path.isfile(api.env.conf_default)
True

Actual behavior

Test fails with IPA client is not configured on this system

Expected behavior

check_client_configuration should not fail

Version/Release/Distribution
