Log Message:
samba: update to 4.17.4.

This is the latest stable release of the Samba 4.17 release series.
It also contains security changes in order to address the following defects:

o CVE-2022-37966: This is the Samba CVE for the Windows Kerberos
                  RC4-HMAC Elevation of Privilege Vulnerability
                  disclosed by Microsoft on Nov 8 2022.

                  A Samba Active Directory DC will issue weak rc4-hmac
                  session keys for use between modern clients and servers
                  despite all modern Kerberos implementations supporting
                  the aes256-cts-hmac-sha1-96 cipher.

                  On Samba Active Directory DCs and members
                  'kerberos encryption types = legacy' would force
                  rc4-hmac as a client even if the server supports
                  aes128-cts-hmac-sha1-96 and/or aes256-cts-hmac-sha1-96.

o CVE-2022-37967: This is the Samba CVE for the Windows
                  Kerberos Elevation of Privilege Vulnerability
                  disclosed by Microsoft on Nov 8 2022.

                  A service account with the special constrained
                  delegation permission could forge a more powerful
                  ticket than the one it was presented with.

                  https://www.samba.org/samba/security/CVE-2022-37967.html

o CVE-2022-38023: The "RC4" protection of the NetLogon Secure channel \ 
uses the
                  same algorithms as rc4-hmac cryptography in Kerberos,
                  and so must also be assumed to be weak.

                  https://www.samba.org/samba/security/CVE-2022-38023.html

Note that there are several important behavior changes
included in this release, which may cause compatibility problems
interacting with system still expecting the former behavior.
Please read the advisories of CVE-2022-37966,
CVE-2022-37967 and CVE-2022-38023 carefully!

samba-tool got a new 'domain trust modify' subcommand
-----------------------------------------------------

This allows "msDS-SupportedEncryptionTypes" to be changed
on trustedDomain objects. Even against remote DCs (including Windows)
using the --local-dc-ipaddress= (and other --local-dc-* options).
See 'samba-tool domain trust modify --help' for further details.
