<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.
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>
<refsect1 id='file-format'>
<title>CONFIGURATION OPTIONS</title>
<para>Refer to the section <quote>DOMAIN SECTIONS</quote> of the
<citerefentry>
<refentrytitle>sssd.conf</refentrytitle>
<manvolnum>5</manvolnum>
</citerefentry> manual page for details on the configuration of an SSSD domain.
<variablelist>
<varlistentry>
<term>ipa_domain (string)</term>
<listitem>
<para>
Specifies the name of the IPA domain.
This is optional. If not provided, the configuration
domain name is used.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>ipa_server (string)</term>
<listitem>
<para>
The comma-separated list of IP addresses or hostnames of the
IPA servers to which SSSD should connect in
the order of preference. For more information
on failover and server redundancy, see the
<quote>FAILOVER</quote> section.
This is optional if autodiscovery is enabled.
For more information on service discovery, refer
to the the <quote>SERVICE DISCOVERY</quote> section.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>ipa_hostname (string)</term>
<listitem>
<para>
Optional. May be set on machines where the
hostname(5) does not reflect the fully qualified
name used in the IPA domain to identify this host.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>ipa_dyndns_update (boolean)</term>
<listitem>
<para>
Optional. This option tells SSSD to automatically
update the DNS server built into FreeIPA v2 with
the IP address of this client.
</para>
<para>
Default: false
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>ipa_dyndns_iface (string)</term>
<listitem>
<para>
Optional. Applicable only when ipa_dyndns_update
is true. Choose the interface whose IP address
should be used for dynamic DNS updates.
</para>
<para>
Default: Use the IP address of the IPA LDAP connection
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>ipa_hbac_search_base (string)</term>
<listitem>
<para>
Optional. Use the given string as search base for
HBAC related objects.
</para>
<para>
Default: Use base DN
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>krb5_validate (boolean)</term>
<listitem>
<para>
Verify with the help of krb5_keytab that the TGT
obtained has not been spoofed.
</para>
<para>
Default: true
</para>
<para>
Note that this default differs from the
traditional Kerberos provider back end.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>krb5_realm (string)</term>
<listitem>
<para>
The name of the Kerberos realm. This is optional and
defaults to the value of <quote>ipa_domain</quote>.
</para>
<para>
The name of the Kerberos realm has a special
meaning in IPA - it is converted into the base
DN to use for performing LDAP operations.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>ipa_hbac_refresh (integer)</term>
<listitem>
<para>
The amount of time between lookups of the HBAC
rules against the IPA server. This will reduce the
latency and load on the IPA server if there are
many access-control requests made in a short
period.
</para>
<para>
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>
</variablelist>
</para>

The following example assumes that SSSD is correctly
configured and example.com is one of the domains in the
