NEW FEATURES/CHANGES
|
||||
====================
|
||||
|
||||
New Minimum MIT Krb5 version for Samba AD Domain Controller
|
||||
-----------------------------------------------------------
|
||||
|
||||
Samba now requires MIT 1.21 when built against a system MIT Krb5 and
|
||||
acting as an Active Directory DC. This addresses the issues that were
|
||||
fixed in CVE-2022-37967 (KrbtgtFullPacSignature) and ensures that
|
||||
Samba builds against the MIT version that allows us to avoid that
|
||||
attack.
|
||||
|
||||
Removed dependency on Perl JSON module
|
||||
--------------------------------------
|
||||
|
||||
Distributions are advised that the Perl JSON package is no longer
|
||||
required by Samba builds that use the imported Heimdal. The build
|
||||
instead uses Perl's JSON::PP built into recent perl5 versions.
|
||||
|
||||
Current lists of packages required by Samba for major distributions
|
||||
are found in the bootstrap/generated-dists/ directory of a Samba
|
||||
source tree. While there will be some differences - due to features
|
||||
chosen by packagers - comparing these lists with the build dependencies
|
||||
in a package may locate other dependencies we no longer require.
|
||||
|
||||
samba-tool user getpassword / syncpasswords ;rounds= change
|
||||
-----------------------------------------------------------
|
||||
|
||||
The password access tool "samba-tool user getpassword" and the
|
||||
password sync tool "samba-tool user syncpasswords" allow attributes to
|
||||
be chosen for output, and accept parameters like
|
||||
pwdLastSet;format=GeneralizedTime
|
||||
|
||||
These attributes then appear, in the same format, as the attributes in
|
||||
the LDIF output. This was not the case for the ;rounds= parameter of
|
||||
virtualCryptSHA256 and virtualCryptSHA512, for example as
|
||||
--attributes="virtualCryptSHA256;rounds=50000"
|
||||
|
||||
This release makes the behaviour consistent between these two
|
||||
features. Installations using GPG-encrypted passwords (or plaintext
|
||||
storage) and the rounds= option, will find the output has changed
|
||||
|
||||
from:
|
||||
virtualCryptSHA256: {CRYPT}$5$rounds=2561$hXem.M9onhM9Vuix$dFdSBwF
|
||||
|
||||
to:
|
||||
virtualCryptSHA256;rounds=2561: {CRYPT}$5$rounds=2561$hXem.M9onhM9Vuix$dFdSBwF
|
||||
|
||||
Group Managed service account client-side features
|
||||
--------------------------------------------------
|
||||
|
||||
samba-tool has been extended to provide client-side support for Group
|
||||
Managed Service accounts. These accounts have passwords that change
|
||||
automatically, giving the advantages of service isolation without risk
|
||||
of poor, unchanging passwords.
|
||||
|
||||
Where possible, Samba's existing samba-tool password handling
|
||||
commands, which in the past have only operated against the local
|
||||
sam.ldb have been extended to permit operation against a remote server
|
||||
with authenticated access to "-H ldap://$DCNAME"
|
||||
|
||||
Supported operations include:
|
||||
- reading the current and previous gMSA password via
|
||||
"samba-tool user getpassword"
|
||||
- writing a Kerberos Ticket Granting Ticket (TGT) to a local
|
||||
credentials cache with a new command
|
||||
"samba-tool user get-kerberos-ticket"
|
||||
|
||||
New Windows Search Protocol Client
|
||||
----------------------------------
|
||||
|
||||
Samba now by default builds new experimental Windows Search Protocol (WSP)
|
||||
command line client "wspsearch"
|
||||
|
||||
The "wspsearch" cmd-line utility allows a WSP search request to be sent
|
||||
to a server (such as a windows server) that has the (WSP)
|
||||
Windows Search Protocol service configured and enabled.
|
||||
|
||||
For more details see the wspsearch man page.
|
||||
|
||||
Allow 'smbcacls' to save/restore DACLs to file
|
||||
--------------------------------------------
|
||||
|
||||
'smbcacls' has been extended to allow DACLs to be saved and restored
|
||||
to/from a file. This feature mimics the functionality that windows cmd
|
||||
line tool 'icacls.exe' provides. Additionally files created either
|
||||
by 'smbcalcs' or 'icacls.exe' are interchangeable and can be used by
|
||||
either tool as the same file format is used.
|
||||
|
||||
New options added are:
|
||||
- '--save savefile' Saves DACLs in sddl format to file
|
||||
- '--recurse' Performs the '--save' operation above on directory
|
||||
and all files/directories below.
|
||||
- '--restore savefile' Restores the stored DACLS to files in directory
|
||||
|
||||
REMOVED FEATURES
|
||||
================
|
||||
|
||||
Get locally logged on users from utmp
|
||||
-------------------------------------
|
||||
|
||||
The Workstation Service Remote Protocol [MS-WKST] calls NetWkstaGetInfo
|
||||
level 102 and NetWkstaEnumUsers level 0 and 1 return the list of locally
|
||||
logged on users. Samba was getting the list from utmp, which is not
|
||||
Y2038 safe. This feature has been completely removed and Samba will
|
||||
always return an empty list.
|
||||
|
||||
|
||||
smb.conf changes
|
||||
================
|
||||
|
||||
Parameter Name Description Default
|
