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

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

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.

Since `IPA` provider or SSSD offline the locator plugin for libkrb5
(man 8 sssd_krb5_locator_plugin) can do nothing about this and kinit
fallbacks to the standard libkrb5 algorithm described in `man 5 krb5.conf`.
`krb5.conf` on IPA server doesn't include `kpasswd_server` and kinit
fallbacks to DNS way. DNS (URI or SRV) RRs don't preserve any order
and kinit may contact either master or replica kpasswd servers.
This may result in a password was changed on a replica but was not
replicated to master:
master(kinit)->master(initial)->replica(kpasswd)->master(can't
obtain initial creds with new password)
So, `kpasswd_server` serves as fallback for the offlined locator.
Note: primary_kdc(the former master_kdc) doesn't help here because
it is only used if the initial credentials obtaining fails (see
`krb5_get_init_creds_password` in libkrb5) and not a password change.

PKI has its own internal knowledge of servers and services
in its securitydomain. This has not been cleaned up in the
past but is becoming more of an issue as PKI now relies on its
securitydomain for more things, and it has a healthcheck that
reports inconsistencies.
Removing entries is straightforward using the PKI REST API.
In order to operate on the API access is needed. There was an
unused Security Domain Administrators group that I've added to
the resourceACLS we created for managing the securitydomain.
The ipara user is added as a member of this group. The REST
API binds to the CA using the IPA RA certificate.
Related commits are b3c2197b7e
and ba4df6449a.
These resourceACLS were originally created as a backwards
compatibility mechanism for dogtag v9 and later only created when a
replica was installed purportedly to save a restart. I don't see
any reason to not have these defined. They are apparently needed due
to the PKI database upgrade issues.
In any case if the purpose was to suppress these ACLS it failed
because as soon as a replica with a CA was installed they were as
well, and we need this ACL in order to manage the securitydomain.
