sssd-ipa 5 File Formats and Conventions 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 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. The IPA provider accepts the same options used by the sssd-ldap 5 identity provider and the sssd-krb5 5 authentication provider with some exceptions described below. 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. 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 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 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 updates. Default: Use the IP address of the IPA LDAP connection ipa_hbac_search_base (string) Optional. Use the given string as search base for HBAC related objects. Default: Use base DN 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. krb5_realm (string) The name of the Kerberos realm. This is optional and defaults to the value of ipa_domain. 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. krb5_canonicalize (boolean) Specifies if the host and user principal should be canonicalized when connecting to IPA LDAP and also for AS requests. This feature is available with MIT Kerberos >= 1.7 Default: true ipa_hbac_refresh (integer) 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. Default: 5 (seconds) ipa_hbac_treat_deny_as (string) 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: DENY_ALL: If any HBAC DENY rules are detected, all users will be denied access. IGNORE: SSSD will ignore any DENY rules. Be very careful with this option, as it may result in opening unintended access. Default: DENY_ALL ipa_netgroup_member_of (string) The LDAP attribute that lists netgroup's memberships. Default: memberOf ipa_netgroup_member_user (string) The LDAP attribute that lists system users and groups that are direct members of the netgroup. Default: memberUser ipa_netgroup_member_host (string) The LDAP attribute that lists hosts and host groups that are direct members of the netgroup. Default: memberHost ipa_netgroup_member_ext_host (string) The LDAP attribute that lists FQDNs of hosts and host groups that are members of the netgroup. Default: externalHost ipa_netgroup_domain (string) The LDAP attribute that contains NIS domain name of the netgroup. Default: nisDomainName ipa_host_object_class (string) The object class of a host entry in LDAP. Default: ipaHost ipa_host_fqdn (string) The LDAP attribute that contains FQDN of the host. Default: fqdn The following example assumes that SSSD is correctly configured and example.com is one of the domains in the [sssd] section. This examples shows only the ipa provider-specific options. [domain/example.com] id_provider = ipa ipa_server = ipaserver.example.com ipa_hostname = myhost.example.com sssd.conf5 , sssd-ldap5 , sssd-krb55 , sssd8
