BASIC OPTIONS¶

-r REALM_NAME, --realm=REALM_NAME

The Kerberos realm name for the new IPA deployment.

It is strongly recommended to use an upper-cased name of the primary DNS domain name of your IPA deployment. You will not be able to establish trust with Active Directory unless the realm name is the upper-cased domain name.

The realm name cannot be changed after the installation.

-n DOMAIN_NAME, --domain=DOMAIN_NAME

The primary DNS domain of the IPA deployment, e.g. example.com. This DNS domain should contain the SRV records generated by the IPA server installer. The specified DNS domain must not contain DNS records of any other LDAP or Kerberos based management system (like Active Directory or MIT Kerberos).

It is strongly recommended to use a lower-cased name of the IPA Kerberos realm name.

The primary DNS domain name cannot be changed after the installation.

-p DM_PASSWORD, --ds-password=DM_PASSWORD

The password to be used by the Directory Server for the Directory Manager user.

-a ADMIN_PASSWORD, --admin-password=ADMIN_PASSWORD

The password for the IPA admin user.

--mkhomedir

Create home directories for users on their first login.

--hostname=HOST_NAME

The fully-qualified DNS name of this server.

--ip-address=IP_ADDRESS

The IP address of this server. If this address does not match the address the host resolves to and --setup-dns is not selected, the installation will fail. If the server hostname is not resolvable, a record for the hostname and IP_ADDRESS is added to /etc/hosts. This option can be used multiple times to specify more IP addresses of the server (e.g. multihomed and/or dualstacked server).

Configure chronyd to use this NTP server. This option can be used multiple times and it is used to specify exactly one time server.

--ntp-server=NTP_SERVER

Configure chronyd to use this NTP server. This option can be used multiple times and it is used to specify exactly one time server.

--ntp-pool=NTP_SERVER_POOL

Configure chronyd to use this NTP server pool. This option is meant to be pool of multiple servers resolved as one host name. This pool's servers may vary but pool address will be still same and chrony will choose only one server from this pool.

-N, --no-ntp

Do not configure NTP client (chronyd).

--idstart=IDSTART

The starting user and group id number (default random).

--idmax=IDMAX

The maximum user and group id number (default: idstart+199999). If set to zero, the default value will be used.

--no-hbac-allow

Don't install allow_all HBAC rule. This rule lets any user from any host access any service on any other host. It is expected that users will remove this rule before moving to production.

--ignore-topology-disconnect

Ignore errors reported when IPA server uninstall would lead to disconnected topology.

--ignore-last-of-role

Ignore errors reported when IPA server uninstall would lead to removal of last CA/DNS server or DNSSec master.

--no-ui-redirect

Do not automatically redirect to the Web UI.

--ssh-trust-dns

Configure OpenSSH client to trust DNS SSHFP records.

--no-ssh

Do not configure OpenSSH client.

--no-sshd

Do not configure OpenSSH server.

--subid

Configure SSSD as data source for subid.

--skip-mem-check

Skip checking for minimum required memory

-d, --debug

Enable debug logging when more verbose output is needed.

-U, --unattended

An unattended installation that will never prompt for user input.

--dirsrv-config-file

The path to LDIF file that will be used to modify configuration of dse.ldif during installation of the directory server instance.

CERTIFICATE SYSTEM OPTIONS¶

--external-ca

Generate a CSR for the IPA CA certificate to be signed by an external CA.

--external-ca-type=TYPE

Type of the external CA. Possible values are "generic", "ms-cs". Default value is "generic". Use "ms-cs" to include the template name required by Microsoft Certificate Services (MS CS) in the generated CSR (see --external-ca-profile for full details).

--external-ca-profile=PROFILE_SPEC

Specify the certificate profile or template to use at the external CA.

When --external-ca-type is "ms-cs" the following specifiers may be used:

--pkinit-cert-name=NAME

Name of the Kerberos KDC SSL certificate to install.

--ca-cert-file=FILE

File containing the CA certificate of the CA which issued the Directory Server, Apache Server and Kerberos KDC certificates. The file is accepted in PEM and DER certificate and PKCS#7 certificate chain formats. This option may be used multiple times. Use this option if the CA certificate is not present in the certificate files.

--pki-config-override=FILE

--ca-signing-algorithm=ALGORITHM

Signing algorithm of the IPA CA certificate. Possible values are SHA1withRSA, SHA256withRSA, SHA384withRSA, SHA512withRSA. Default value is SHA256withRSA. Use this option with --external-ca if the external CA does not support the default signing algorithm.

SECRET MANAGEMENT OPTIONS¶

--setup-kra

Install and configure a KRA on this server.

DNS OPTIONS¶

IPA provides an integrated DNS server which can be used to simplify IPA deployment. If you decide to use it, IPA will automatically maintain SRV and other service records when you change your topology.

The DNS component in IPA is optional and you may choose to manage all your DNS records manually on another third party DNS server. IPA DNS is not a general-purpose DNS server. If you need advanced features like DNS views, do not deploy IPA DNS.

--setup-dns

Configure an integrated DNS server, create DNS zone specified by --domain, and fill it with service records necessary for IPA deployment. In cases where the IPA server name does not belong to the primary DNS domain and is not resolvable using DNS, create a DNS zone containing the IPA server name as well.

This option requires that you either specify at least one DNS forwarder through the --forwarder option or use the --no-forwarders option.

Note that you can set up a DNS at any time after the initial IPA server install by running ipa-dns-install (see ipa-dns-install(1)). IPA DNS cannot be uninstalled.

--forwarder=IP_ADDRESS

Add a DNS forwarder to the DNS configuration. You can use this option multiple times to specify more forwarders, but at least one must be provided, unless the --no-forwarders option is specified.

--no-forwarders

Do not add any DNS forwarders. Root DNS servers will be used instead.

--auto-forwarders

Add DNS forwarders configured in /etc/resolv.conf to the list of forwarders used by IPA DNS.

--forward-policy=first|only

DNS forwarding policy for global forwarders specified using other options. Defaults to first if no IP address belonging to a private or reserved ranges is detected on local interfaces (RFC 6303). Defaults to only if a private IP address is detected.

--reverse-zone=REVERSE_ZONE

The reverse DNS zone to use. This option can be used multiple times to specify multiple reverse zones.

--no-reverse

Do not create reverse DNS zone.

--auto-reverse

Try to resolve reverse records and reverse zones for server IP addresses. If neither is resolvable, creates the reverse zones.

--zonemgr

The e-mail address of the DNS zone manager. Defaults to hostmaster@DOMAIN

--no-host-dns

Do not use DNS for hostname lookup during installation.

--no-dns-sshfp

Do not automatically create DNS SSHFP records.

--no-dnssec-validation

Disable DNSSEC validation on this server.

--allow-zone-overlap

Allow creation of (reverse) zone even if the zone is already resolvable. Using this option is discouraged as it result in later problems with domain name resolution.

SID GENERATION OPTIONS¶

--netbios-name=NETBIOS_NAME

The NetBIOS name for the IPA domain. If not provided, this is determined based on the leading component of the DNS domain name. Running ipa-adtrust-install for a second time with a different NetBIOS name will change the name. Please note that changing the NetBIOS name might break existing trust relationships to other domains.

--rid-base=RID_BASE

First RID value of the local domain. The first POSIX ID of the local domain will be assigned to this RID, the second to RID+1 etc. See the online help of the idrange CLI for details.

--secondary-rid-base=SECONDARY_RID_BASE

Start value of the secondary RID range, which is only used in the case a user and a group share numerically the same POSIX ID. See the online help of the idrange CLI for details.

AD TRUST OPTIONS¶

--setup-adtrust

Configure AD Trust capability.

--enable-compat

Enables support for trusted domains users for old clients through Schema Compatibility plugin. SSSD supports trusted domains natively starting with version 1.9. For platforms that lack SSSD or run older SSSD version one needs to use this option. When enabled, slapi-nis package needs to be installed and schema-compat-plugin will be configured to provide lookup of users and groups from trusted domains via SSSD on IPA server. These users and groups will be available under cn=users,cn=compat,$SUFFIX and cn=groups,cn=compat,$SUFFIX trees. SSSD will normalize names of users and groups to lower case.

In addition to providing these users and groups through the compat tree, this option enables authentication over LDAP for trusted domain users with DN under compat tree, i.e. using bind DN uid=administrator@ad.domain,cn=users,cn=compat,$SUFFIX.

LDAP authentication performed by the compat tree is done via PAM 'system-auth' service. This service exists by default on Linux systems and is provided by pam package as /etc/pam.d/system-auth. If your IPA install does not have default HBAC rule 'allow_all' enabled, then make sure to define in IPA special service called 'system-auth' and create an HBAC rule to allow access to anyone to this rule on IPA masters.

As 'system-auth' PAM service is not used directly by any other application, it is safe to use it for trusted domain users via compatibility path.

UNINSTALL OPTIONS¶

--uninstall

Uninstall an existing IPA installation.

-U, --unattended

An unattended uninstallation that will never prompt for user input.
