The installer would then fail to discover the IPA server and exit with error. Such DNS SRV records may break the installation if the installer discovers these DNS records before it finds DNS SRV records pointing to IPA servers. Microsoft Active Directory) may use the same DNS SRV records to denote hosts with a directory service (_ldap._tcp.DOMAIN). Other directory servers deployed in the network (e.g. Please note, that in case of a fixed list of IPA servers, the fixed server lists in client components need to be updated when a new IPA server is enrolled or a current IPA server is decommissioned. When only one IPA server is configured, IPA client services will not be available in case of a failure of the IPA server. If DNS autodiscovery is not available, clients should be configured at least with a fixed list of IPA servers that can be used in case of a failure. When client machine is configured to use DNS SRV record autodiscovery (no fixed server was passed to the installer), client components do the fallback automatically, based on the IPA server hostnames and priorities discovered from the DNS SRV records. When some of the IPA servers is not available, client components are able to fallback to other IPA replica and thus preserving a continued service.

When -fixed-primary option is specified, SSSD will not try to read DNS SRV record at all (see sssd-ipa(5) for details). SSSD is still configured to either try to read domain's SRV records or the specified fixed list of servers. Without DNS autodiscovery, Kerberos is configured with a fixed list of KDC and Admin servers. server option accepts multiple server hostnames which can be used for failover mechanism. When both -server and -domain options are used, client installer will use the specified server and domain directly. In that case, both SSSD and Kerberos components have the domain set in the configuration files and will use it to autodiscover IPA servers.Д¬lient machine can also be configured without a DNS autodiscovery at all. When the client machine hostname is not in a subdomain of an IPA server, its domain can be passed with -domain option. SSSD and Kerberos 5 configuration) on the machine. The discovered domain is then used to configure client components (e.g. For example, if a client machine has a hostname '', the installer will try to retrieve an IPA server hostname from _ldap._, _ldap._ and _ldap._tcp.com DNS SRV records, respectively. hostname option may be used to specify a static hostname that persists over reboot.Д¬lient installer by default tries to search for _ldap._tcp.DOMAIN DNS SRV records for all domains that are parent to its hostname. If the machine hostname changes for example due to a dynamic hostname assignment by a DHCP server, client enrollment to IPA server breaks and user then would not be able to perform Kerberos authentication. If SSH keys are not present (e.g when running the ipa-client-install in a kickstart, before ever running sshd), they will not be uploaded to the client host entry on the server.Д¬lient must use a static hostname. It will not generate SSH keys of its own accord. The ipa-client-install script assumes that the machine has already generated SSH keys. If this principal does not exist then unenrollment will fail and an administrator will need to disable the host principal (ipa host-disable ). The machine principal in /etc/krb5.keytab is used to authenticate to the IPA server to unenroll itself. Unenrollment consists of disabling the principal key on the IPA server so that it may be re-enrolled. Part of this process is to unenroll the host from the IPA server. This same tool is used to unconfigure IPA and attempts to return the machine to its previous state.

This can take the form of a kerberos principal or a one-time password associated with the machine. Optionally one can instead configure PAM and NSS (Name Switching Service) to work with an IPA server over Kerberos and LDAP.ДЄn authorized user is required to join a client machine to IPA. By default this configures SSSD to connect to an IPA server for authentication and authorization.
