ipa-client-install no longer overrides SSH client settings for
HostKeyAlgorithms. It's no longer necessary to configure
HostKeyAlgorithms. The setting was disabling modern algorithms and
enabled a weak algorithm that is blocked in FIPS code.
The ipa-client package removes IPA's custom HostKeyAlgorithm from
/etc/ssh/ssh_config during package update. Non-IPA settings are not
touched.

If certmonger is running prior to client installation then its
IPA CA configuration will be incomplete and missing the CA chain.
If a certificate is subsequently requested with -F to store the
CA chain in a file or NSS db it may not be available yet. A
conditional restart of certmonger will pick up the new IPA
configuration and complete the IPA CA configuration in certmonger.
A pure restart and service activation is not done since certmonger
is not required unless --request-cert was passed ipa-client-install.

Instead it wants the user to write to

To complicate matters some databases are not user configurable

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.
