UPGRADING
NEW FEATURES/CHANGES
====================
-New samba-dcerpcd binary to provide DCERPC in the member server setup
----------------------------------------------------------------------
-
-In order to make it much easier to break out the DCERPC services
-from smbd, a new samba-dcerpcd binary has been created.
-
-samba-dcerpcd can be used in two ways. In the normal case without
-startup script modification it is invoked on demand from smbd or
-winbind --np-helper to serve DCERPC over named pipes. Note that
-in order to run in this mode the smb.conf [global] section has
-a new parameter "rpc start on demand helpers = [true|false]".
-This parameter is set to "true" by default, meaning no changes to
-smb.conf files are needed to run samba-dcerpcd on demand as a named
-pipe helper.
-
-It can also be used in a standalone mode where it is started
-separately from smbd or winbind but this requires changes to system
-startup scripts, and in addition a change to smb.conf, setting the new
-[global] parameter "rpc start on demand helpers = false". If "rpc
-start on demand helpers" is not set to false, samba-dcerpcd will
-refuse to start in standalone mode.
-
-Note that when Samba is run in the Active Directory Domain Controller
-mode the samba binary that provides the AD code will still provide its
-normal DCERPC services whilst allowing samba-dcerpcd to provide
-services like SRVSVC in the same way that smbd used to in this
-configuration.
-
-The parameters that allowed some smbd-hosted services to be started
-externally are now gone (detailed below) as this is now the default
-setting.
-
-samba-dcerpcd can also be useful for use outside of the Samba
-framework, for example, use with the Linux kernel SMB2 server ksmbd or
-possibly other SMB2 server implementations.
-
-Certificate Auto Enrollment
----------------------------
-
-Certificate Auto Enrollment allows devices to enroll for certificates from
-Active Directory Certificate Services. It is enabled by Group Policy.
-To enable Certificate Auto Enrollment, Samba's group policy will need to be
-enabled by setting the smb.conf option `apply group policies` to Yes. Samba
-Certificate Auto Enrollment depends on certmonger, the cepces certmonger
-plugin, and sscep. Samba uses sscep to download the CA root chain, then uses
-certmonger paired with cepces to monitor the host certificate templates.
-Certificates are installed in /var/lib/samba/certs and private keys are
-installed in /var/lib/samba/private/certs.
-
-Ability to add ports to dns forwarder addresses in internal DNS backend
------------------------------------------------------------------------
-
-The internal DNS server of Samba forwards queries non-AD zones to one or more
-configured forwarders. Up until now it has been assumed that these forwarders
-listen on port 53. Starting with this version it is possible to configure the
-port using host:port notation. See smb.conf for more details. Existing setups
-are not affected, as the default port is 53.
REMOVED FEATURES
================
-SMB1 CORE and LANMAN1 protocol wildcard copy, unlink and rename removed
-=======================================================================
-
-In preparation for the removal of the SMB1 server, the unused
-SMB1 command SMB_COM_COPY (SMB1 command number 0x29) has been
-removed from the Samba smbd server. In addition, the ability
-to process file name wildcards in requests using the SMB1 commands
-SMB_COM_COPY (SMB1 command number 0x2A), SMB_COM_RENAME (SMB1 command
-number 0x7), SMB_COM_NT_RENAME (SMB1 command number 0xA5) and
-SMB_COM_DELETE (SMB1 command number 0x6) have been removed.
-
-This only affects clients using MS-DOS based versions of
-SMB1, the last release of which was Windows 98. Users requiring
-support for these features will need to use older versions
-of Samba.
-
-No longer using Linux mandatory locks for sharemodes
-====================================================
-
-smbd mapped sharemodes to Linux mandatory locks. This code in the Linux kernel
-was broken for a long time, and is planned to be removed with Linux 5.15. This
-Samba release removes the usage of mandatory locks for sharemodes and the
-"kernel share modes" config parameter is changed to default to "no". The Samba
-VFS interface is kept, so that file-system specific VFS modules can still use
-private calls for enforcing sharemodes.
-
smb.conf changes
================
Parameter Name Description Default
-------------- ----------- -------
- kernel share modes New default No
- dns forwarder Changed
- rpc_daemon Removed
- rpc_server Removed
- rpc start on demand helpers Added true
