<title>DESCRIPTION</title>
<para>
This manual page describes the configuration of the IPA provider
for
<citerefentry>
<refentrytitle>sssd</refentrytitle>
<manvolnum>8</manvolnum>
</citerefentry>.
For a detailed syntax reference, refer to the <quote>FILE FORMAT</quote> section of the
<citerefentry>
<refentrytitle>sssd.conf</refentrytitle>
<manvolnum>5</manvolnum>
</citerefentry> manual page.
</para>
<para>
The IPA provider is a back end used to connect to an IPA server.
(Refer to the freeipa.org web site for information about IPA servers.)
This provider requires that the machine be joined to the IPA domain;
configuration is almost entirely self-discovered and obtained
directly from the server.
</para>
<para>
The IPA provider accepts the same options used by the
<citerefentry>
<refentrytitle>sssd-ldap</refentrytitle>
<manvolnum>5</manvolnum>
</citerefentry> identity provider and the
<citerefentry>
<refentrytitle>sssd-krb5</refentrytitle>
<manvolnum>5</manvolnum>
</citerefentry> authentication provider with some exceptions described
below.
</para>
<para>
However, it is neither necessary nor recommended to set these options.
IPA provider can also be used as an access and chpass provider. As an
access provider it uses HBAC (host-based access control) rules. Please
refer to freeipa.org for more information about HBAC. No configuration
of access provider is required on the client side.
</para>

<refsect1 id='file-format'>

</varlistentry>
<varlistentry>

Default: 5 (seconds)
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>ipa_hbac_treat_deny_as (string)</term>
<listitem>
<para>
This option specifies how to treat the deprecated
DENY-type HBAC rules. As of FreeIPA v2.1, DENY
rules are no longer supported on the server. All
users of FreeIPA will need to migrate their rules
to use only the ALLOW rules. The client will
support two modes of operation during this
transition period:
</para>
<para>
<emphasis>DENY_ALL</emphasis>: If any HBAC DENY
rules are detected, all users will be denied
access.
</para>
<para>
<emphasis>IGNORE</emphasis>: SSSD will ignore any
DENY rules. Be very careful with this option, as
it may result in opening unintended access.
</para>
<para>
Default: DENY_ALL
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>ipa_hbac_support_srchost (boolean)</term>

<emphasis>ipa_host_search_base</emphasis> to be ignored;
</para>
