Rob Crittenden 82c0b19acc Add HSM configuration options to installer scripts
The bulk of the installer effort to enable HSM support without
having to provide an override file.

This pulls the HSM configuration from a remote server when installing
a replica so that the token name and library don't need to be
passed with every installation.

Rob Crittenden f78d25fc97 ipa-crlgen-manage: manage the cert status task execution time
ca.certStatusUpdateInterval manages how frequently to update
the certificate status in LDAP (expired, etc).

By default this is not set on the initial master and pkispawn sets
it to 0 on replicas. This can lead to no server running this
task and therefore the status attribute not reflecting the current
state.

On enabling CRL generation remove any value which will cause PKI
to use its default. On disabling set it to 0.

Only one server should run the update status task to prevent
unnecessary replication.

two hosts where possible so if a CA or KRA is requested then
we only try to install against a remote server that also provides

If a CA or KRA is not requested and the user has provided a
server to install against then use that instead of overriding it.

Extend the logic of picking the remote Custodia mode
(KRA, CA, *MASTER*) to include considering whether the
CA and KRA services are requested. If the service(s) are
not requested the the associated hostname may not be

Rob Crittenden 45fa43540f Configure affinity during server installation
Write a new krb5.conf in case any values changed finding the
right server to configure against (e.g. for CA, KRA) and
ensure the API connection is to the remote server that
will be installed against.

When finding a CA or KRA during initial replica installation
set the remote master as well. The order is:

 - existing server value in /etc/ipa/default.conf
 - the chosen CA host if the server doesn't provide one
 - the chosen KRA host if the server doesn't provide one

This is more or less heirarchical. If a server is provided
then that is considered first. If it provides all the
optional services needed (CA and/or KRA) then it will
be used. Otherwise it will fall back to a server that provides
all the required services.

In short, providing --server either at client install or
with ipa-replica-install is no guarantee that it will
define all topology. This may be unexpected behavior.

For the case of adding a CA or KRA things are effectively
unchanged. This type of install does not appear to be
impacted by affinity issues.

Julien Rische 3f1b373cb2 Tolerate absence of PAC ticket signature depending of server capabilities
Since November 2020, Active Directory KDC generates a new type of
signature as part of the PAC. It is called "ticket signature", and is
generated based on the encrypted part of the ticket. The presence of
this signature is not mandatory in order for the PAC to be accepted for
S4U requests.

However, the behavior is different for MIT krb5. Support was added as
part of the 1.20 release, and this signature is required in order to
process S4U requests. Contrary to the PAC extended KDC signature, the
code generating this signature cannot be isolated and backported to
older krb5 versions because this version of the KDB API does not allow
passing the content of the ticket's encrypted part to IPA.

This is an issue in gradual upgrade scenarios where some IPA servers
rely on 1.19 and older versions of MIT krb5, while others use version
1.20 or newer. A service ticket that was provided by 1.19- IPA KDC will
be rejected when used by a service against a 1.20+ IPA KDC for S4U
requests.

On Fedora, CentOS 9 Stream, and RHEL 9, when the krb5 version is 1.20 or
newer, it will include a downstream-only update adding the
"optional_pac_tkt_chksum" KDB string attribute allowing to tolerate the
absence of PAC ticket signatures, if necessary.

This commit adds an extra step during the installation and update
processes where it adds a "pacTktSignSupported" ipaConfigString
attribute in "cn=KDC,cn=[server],cn=masters,cn=ipa,cn=etc,[basedn]" if
the MIT krb5 version IPA what built with was 1.20 or newer.

This commit also set "optional_pac_tkt_chksum" as a virtual KDB entry
attribute. This means the value of the attribute is not actually stored
in the database (to avoid race conditions), but its value is determined
at the KDC starting time by search the "pacTktSignSupported"
ipaConfigString in the server list. If this value is missing for at
least of them is missing, enforcement of the PAC ticket signature is
disabled by setting "optional_pac_tkt_chksum" to true for the local
realm TGS KDB entry.

For foreign realm TGS KDB entries, the "optional_pac_tkt_chksum" virtual
string attribute is set to true systematically, because, at least for
now, trusted AD domains can still have PAC ticket signature support
disabled.

Given the fact the "pacTktSignSupported" ipaConfigString for a single
server is added when this server is updated, and that the value of
"optional_pac_tkt_chksum" is determined at KDC starting time based on
the ipaConfigString attributes of all the KDCs in the domain, this
requires to restart all the KDCs in the domain after all IPA servers
were updated in order for PAC ticket signature enforcement to actually
take effect.

Christian Heimes 903c8f9dcf Speed up installer by restarting DS after DNA plugin
DS does not enable plugins unless nsslapd-dynamic-plugins is enabled or
DS is restarted. The DNA plugin creates its configuration entries with
some delay after the plugin is enabled.

DS is now restarted after the DNA plugin is enabled so it can create the
entries while Dogtag and the rest of the system is installing. The
updater `update_dna_shared_config` no longer blocks and waits for two
times 60 seconds for `posix-ids` and `subordinate-ids`.

Replace comparisons of "if value" with "if value is not None"
in order to handle 0.

Add a short reference to the man page to indicat that a cert
or request retention time of 0 means remove at the next
execution.

Also indicate that the search time limit is in seconds.

Rob Crittenden 78298fd4e1 ipa-acme-manage: add certificate/request pruning management
Configures PKI to remove expired certificates and non-resolved
requests on a schedule.

This is geared towards ACME which can generate a lot of certificates
over a short period of time but is general purpose. It lives in
ipa-acme-manage because that is the primary reason for including it.

Random Serial Numbers v3 must be enabled for this to work.

Enabling pruning enables the job scheduler within CS and sets the
job user as the IPA RA user which has full rights to certificates
and requests.

Disabling pruning does not disable the job scheduler because the
tool is stateless. Having the scheduler enabled should not be a
problem.

A restart of PKI is required to apply any changes. This tool forks
out to pki-server which does direct writes to CS.cfg. It might
be easier to use our own tooling for this but this makes the
integration tighter so we pick up any improvements in PKI.

The "cron" setting is quite limited, taking only integer values
and *. It does not accept ranges, either - or /.

No error checking is done in PKI when setting a value, only when
attempting to use it, so some rudimentary validation is done.

Florence Blanc-Renaud ad05218450 Installer: create RID base before domain object
The installer is currently creating the samba domain object
before it adds the RID base and secondary RID base. As a consequence,
there is a window during which the sidgen plugin is active but
unable to generate SIDs (it requires the samba domain object to
find the domain SID and RID base to know where to start from).
There is no direct impact except the error log of 389ds that reports
ERR - get_ranges - [file ipa_sidgen_common.c, line 276]: Failed to convert LDAP entry to range struct.

This fix configures the RID base and secondary RID base before the
domain object is created, thus removing this window.
