ACME support requires TLS and we want ACME clients to access the
service via the ipa-ca.$DOMAIN DNS name. So we need to add the
ipa-ca.$DOMAIN dNSName to IPA servers' HTTP certificates. To
facilitiate this, add a special case to the cert-request command
processing. The rule is:
- if the dnsName being validated is "ipa-ca.$DOMAIN"
- and the subject principal is an "HTTP/..." service
- and the subject principal's hostname is an IPA server
Then that name (i.e. "ipa-ca.$DOMAIN") is immediately allowed.
Otherwise continue with the usual dnsName validation.

BACKGROUND:
We are implementing ACME support in FreeIPA (umbrella ticket:
https://pagure.io/freeipa/issue/4751). ACME is defined in RFC 8555.
HTTPS is REQUIRED (https://tools.ietf.org/html/rfc8555#section-6.1).
Therefore, every FreeIPA server that provides the ACME service
capability must be reachable by HTTPS.
RFC 8555 does not say anything about which port to use for ACME.
The default HTTPS port of 443 is implied. Therefore, the FreeIPA
ACME service will be reached via the Apache httpd server, which will
be the TLS server endpoint.
As a usability affordance for ACME clients, and as a maintainability
consideration i.e. to allow the topology to change without having to
reconfigure ACME clients, there should be a a single DNS name used
to reach the IPA ACME service.
The question then, is which DNS name to use.
REQUIREMENTS:
Each FreeIPA server that is also an ACME server must:
1. Be reachable via a common DNS name
2. Have an HTTP service certificate with that DNS name as a SAN
dNSName value
DESIGN CONSIDERATION - WHAT DNS NAME TO USE?:
Some unrelated FreeIPA ACME design decisions provide important
context for the DNS name decision:
- The ACME service will be automatically and unconditionally
deployed (but not necessarily *enabled*) on all CA servers.
- Enabling or disabling the ACME service will have topology-wide
effect, i.e. the ACME service is either enabled on all CA
servers, or disabled on all CA servers.
In a CA-ful FreeIPA deployment there is already a DNS name that
resolves to all CA servers: ``ipa-ca.$DOMAIN``, e.g.
``ipa-ca.example.com``. It is expected to point to all CA servers
in the deployment, and *only* to CA servers. If internal DNS is
deployed, the DNS records for ``ipa-ca.$DOMAIN`` are created and
updated automatically. If internal DNS is not deployed,
administrators are required to maintain these DNS records
themselves.
The ``ipa-ca.$DOMAIN`` alias is currently used for OCSP and CRL
access. TLS is not required for these applications (and it can
actually be problematic for OCSP). Enabling TLS for this name
presents some risk of confusion for operators. For example, if they
see that TLS is available and alter the certificate profiles to
include an HTTPS OCSP URL in the Authority Information Access (AIA)
extension, OCSP-using clients may fail to validate such
certificates. But it is possible for administrators to make such a
change to the profile, whether or not HTTPS is available.
One big advantage to using the ``ipa-ca.$DOMAIN`` DNS name is that
there are no new DNS records to manage, either in the FreeIPA
implementation or for administrators in external DNS systems.
The alternative approach is to define a new DNS name, e.g.
``ipa-acme.$DOMAIN``, that ACME clients would use. For internal
DNS, this means the FreeIPA implementation must manage the DNS
records. This is straightforward; whenever we add or remove an
``ipa-ca.$DOMAIN`` record, also add/remove the ``ipa-acme.$DOMAIN``
record. But for CA-ful deployments using external DNS, it is
additional work for adminstrators and, unless automated, additional
room for error.
An advantage of using a different DNS name is ``ipa-ca.$DOMAIN`` can
remain inaccessible over HTTPS. This possibly reduces the risk of
administrator confusion or creation of invalid AIA configuration in
certificate profiles.
Weighing up the advantages and disadvantages, I decided to use the
``ipa-ca.$DOMAIN`` DNS name.
DESIGN CONSIDERATION - CA SERVERS, OR ALL SERVERS?:
A separate decision from which name to use is whether to include it
on the HTTP service certificate for ACME servers (i.e. CA servers)
only, or on all IPA servers.
Combined with the assumption that the chosen DNS name points to CA
servers *only*, there does not seem to be any harm in adding it to
the certificates on all IPA servers.
The alternative is to only include the chosen DNS name on the HTTP
service certificates of CA servers. This approach entails some
additional complexity:
- If a non-CA replica gets promoted to CA replica (i.e. via
``ipa-ca-install``), its HTTP certificate must be re-issued with
the relevant name.
- ipa-server-upgrade code must consider whether the server is a CA
replica when validating (and if necessary re-creating) Certmonger
tracking requests
- IPA Health Check must be made aware of this factor when checking
certificates and Certmonger tracking requests.
Weighing up the options, I decided to add the common DNS name to the
HTTP service certificate on all IPA servers. This avoids the
implementation complexity discussed above.
CHANGES IN THIS COMMIT
When (re-)tracking the HTTP certificate, explicitly add the server
FQDN and ipa-ca.$DOMAIN DNS names to the Certmonger tracking request.

Previously, FreeIPA only allowed to issue PAC record in a ticket
for the following principal types:
- for IPA users
- for a host principal of one of IPA masters
- for a cifs/ or HTTP/ service on one of IPA masters
To allow S4U2Self operations over trust to AD, an impersonating service
must have PAC record in its TGT to be able to ask AD DCs for a S4U2Self
ticket. It means any IPA service performing S4U2Self would need to have
PAC record and the constraints above prevent it from doing so.
However, depending on whether the service or host principal belongs to
one of IPA masters, we need to set proper primary RID to 516 (domain
controllers) or 515 (domain computers).

Implement minimal server referrals support for enterprise principals as

S4U extensions. We have to verify/sign PAC and take the realm into
account for S4U in these cases.
The use of extended functions require krb5 1.17+.
For PAC verification, we have to filter existing PAC CLIENT-INFO
structure in cross-realm S4U case because otherwise old CLIENT-INFO
would change the PAC principal due to adding or ommiting the realm in
transition. Since a new PAC CLIENT-INFO will be provided by
k5_insert_client_info() anyway, we can filter it in all cases.
Generate PAC only for the first S4U2Self request to the client realm
(client != NULL). Otherwise, use the PAC from the cross-realm ticket.
The latter PAC belongs to the impersonated user.
Foreign (inner) principal look up in non-AS request returns
KRB5_KDB_NOENTRY.
Finally, in PAC signing we have to take the realm into account as well
for S4U2Self cross-realm operation. This does not work when compiling
against krb5 1.17 at the moment because sign_authdata() callback does
not know whether we are dealing with an issuing referral or not. In 1.18
a KDC will set a special client flag to signify this when asking KDB

In direct ticket acquisition mode the utility first does one of the
following actions:
- obtain a TGT ticket for a user principal using supplied password
- import existing TGT from a default credentials cache
Once a user TGT is available, the utility will attempt to acquire a service
ticket to a service which key is specified in a keytab (default or
passed with --keytab option) and simulate establishing context to the
service application.
If establishing context succeeds, MS-PAC content of the service ticket
will be printed out.
2. S4U2Self protocol transition
In protocol transition case a service application obtains own TGT using
a key from the keytab and then requests a service ticket to itself in
the name of the user principal, performing S4U2Self request.
If accepting this service ticket succeeds, MS-PAC content of the service
ticket will be printed out.
If KDC does not support or rejects issuing MS-PAC record for a user, an
