       sssd-ipa - the configuration file for SSSD


       This manual page describes the configuration of the IPA provider for
       sssd(8). For a detailed syntax reference, refer to the "FILE FORMAT"
       section of the sssd.conf(5) manual page.

       The IPA provider is a back end used to connect to an IPA server. (Refer
       to the 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.

       The IPA provider accepts the same options used by the sssd-ldap(5)
       identity provider and the sssd-krb5(5) authentication provider.
       However, it is neither necessary nor recommended to set these options.


       Refer to the section "DOMAIN SECTIONS" of the sssd.conf(5) manual page
       for details on the configuration of an SSSD domain.

       ipa_domain (string)
           Specifies the name of the IPA domain. This is optional. If not
           provided, the configuration domain name is used.

       ipa_server (string)
           The 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 "FAILOVER"
           section. This is optional if autodiscovery is enabled. For more
           information on service discovery, refer to the the "SERVICE
           DISCOVERY" section.

       ipa_hostname (string)
           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.

       ipa_dyndns_update (boolean)
           Optional. This option tells SSSD to automatically update the DNS
           server built into FreeIPA v2 with the IP address of this client.

           Default: false

       ipa_dyndns_iface (string)
           Optional. Applicable only when ipa_dyndns_update is true. Choose
           the interface whose IP address should be used for dynamic DNS

           Default: Use the IP address of the IPA LDAP connection

       krb5_validate (boolean)
           Verify with the help of krb5_keytab that the TGT obtained has not
           been spoofed.

           Default: true

           Note that this default differs from the traditional Kerberos
           provider back end.


       The failover feature allows back ends to automatically switch to a
       different server if the primary server fails.

   Failover Syntax
       The list of servers is given as a comma-separated list; any number of
       spaces is allowed around the comma. The servers are listed in order of
       preference. The list can contain any number of servers.

   The Failover Mechanism
       The failover mechanism distinguishes between a machine and a service.
       The back end first tries to resolve the hostname of a given machine; if
       this resolution attempt fails, the machine is considered offline. No
       further attempts are made to connect to this machine for any other
       service. If the resolution attempt succeeds, the back end tries to
       connect to a service on this machine. If the service connection attempt
       fails, then only this particular service is considered offline and the
       back end automatically switches over to the next service. The machine
       is still considered online and might still be tried for another

       Further connection attempts are made to machines or services marked as
       offline after a specified period of time; this is currently hard coded
       to 30 seconds.

       If there are no more machines to try, the back end as a whole switches
       to offline mode, and then attempts to reconnect every 30 seconds.


       The service discovery feature allows back ends to automatically find
       the appropriate servers to connect to using a special DNS query.

       If no servers are specified, the back end automatically uses service
       discovery to try to find a server. Optionally, the user may choose to
       use both fixed server addresses and service discovery by inserting a
       special keyword, "_srv_", in the list of servers. The order of
       preference is maintained. This feature is useful if, for example, the
       user prefers to use service discovery whenever possible, and fall back
       to a specific server when no servers can be discovered using DNS.

   The domain name
       The name of the SSSD domain is used as the domain part of the service
       discovery DNS query.
