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
to manually handle the config upgrade.

EPN stands for Expiring Password Notification. It is a standalone
tool designed to build a list of users whose password would expire
in the near future, and either display the list in a machine-readable
format, or send email notifications to these users.
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)
or replica from a systemd timer.
EPN does not keep state. The list of affected users is built at runtime
but never kept.

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
in all required dependencies for Samba and cifs.ko (smb3.ko) kernel
module. This allows an IPA client to become both an SMB server and an
SMB client.
