This command doesn't require any permissions that a host doesn't
already have and it simplifies overall credential handling.
It also corrects the case where the server API cache is out of
date and there are no credentials available to refresh it which
can lead to a confusing error message.
Also switch to MEMORY-based ccache rather than file to avoid
having to clean up the filesystem.

FreeIPA's Python and C code used different approaches to get the FQDN of
the host. Some places assumed that gethostname() returns a FQDN. Other
code paths used glibc's resolver to resolve the current node name to a
FQDN.
Python code now uses the ipalib.constants.FQDN where a fully qualified
domain name is expected. The variable is initialized only once and avoids
potential DNS lookups.
C code uses a new helper function ipa_gethostfqdn() in util package. The
function implements similar logic as gethostfqdn() except it uses more
modern getaddrinfo(). The result is cached as well.

`dnspython` 2.0.0 has many changes and several deprecations like:
```
> dns.resolver.resolve() has been added, allowing control of whether
search lists are used. dns.resolver.query() is retained for backwards
compatibility, but deprecated. The default for search list behavior can
be set at in the resolver object with the use_search_by_default
parameter. The default is False.
> dns.resolver.resolve_address() has been added, allowing easy
address-to-name lookups.
```
The new class `DNSResolver`:
- provides the compatibility layer
- defaults the previous behavior (the search list configured in the
system's resolver configuration is used for relative names)
- defaults lifetime to 15sec (determines the number of seconds
to spend trying to get an answer to the question)

When a deployment gets promoted from CA-less to CA-ful other
replicas still have enable_ra=False in default.conf, and do not have
the ra-agent key and certificate. Enhance ipa-certupdate to detect
when the deployment has become CA-ful; retrieve the ra-agent
credential and update default.conf.
The rationale for adding this behaviour to ipa-certupdate is that it
is already necessary to use this command to update local trust
stores with the new CA certificate(s). So by using ipa-certupdate
we avoid introducing additional steps for administrators.
It is necessary to choose a CA master to use as the ca_host. We use
the first server returned by LDAP. A better heuristic might be to
choose a master in the same location but this is just left as a
comment unless or until the need is proven.
Finally, defer the httpd service restart until after the possible
update of default.conf so that the IPA API executes with the new
configuration.
This change also addresses the case of a CA server being removed
from the topology, i.e. ipa-certupdate detects when non-CA replicas
are pointing at the removed server, and chooses a new ca_host.
HOW TO TEST:
1. Install a CA-less server (first server).
2. Install a CA-less replica.
3. Run 'ipa-ca-install' on first server, promoting deployment from
CA-less to CA-ful.
4. Run 'ipa-certupdate' on second server.
5. Exceute 'ipa cert-show 5' on second server. Should succeed,
because ra-agent credential was retrieved and default.conf
updated at step #4.

sshd 8.2+ now supports the "Include" keyword in sshd_config and
ships by default /etc/ssh/sshd_config with
"Include /etc/ssh/sshd_config.d/*"
As fedora 32 provides a config file in that directory (05-redhat.conf) with
ChallengeResponseAuthentication no
that is conflicting with IPA client config, ipa-client-install now needs
to make its config changes in a drop-in file read before 05-redhat.conf
(the files are read in lexicographic order and the first setting wins).
There is no need to handle upgrades from sshd < 8.2: if openssh-server
detects a customisation in /etc/ssh/sshd_config, it will not update
the file but create /etc/ssh/sshd_config.rpmnew and ask the admin

EPN stands for Expiring Password Notification. It is a standalone

EPN provides command-line options to display the list of affected users.
This provides data introspection and helps understand how many emails
would be sent for a given day, or a given date range.
The command-line options can also be used by a monitoring system to alert
whenever a number of emails over the SMTP quota would be sent.
EPN is meant to be launched once a day from an IPA client (preferred)

Introduces new utility to configure Samba on an IPA domain member.
The tool sets up Samba configuration and internal databases, creates
cifs/... Kerberos service and makes sure that a keytab for this service
contains the key with the same randomly generated password that is set
in the internal Samba databases.
Samba configuration is created by querying an IPA master about details
of trust to Active Directory configuration. All known identity ranges
added to the configuration to allow Samba to properly handle them
(read-only) via idmap_sss.
Resulting configuration allows connection with both NTLMSSP and Kerberos
authentication for IPA users. Access controls for the shared content
should be set by utilizing POSIX ACLs on the file system under a
specific share.
The utility is packaged as freeipa-client-samba package to allow pulling
