Release Announcements ===================== This is the first preview release of Samba 4.11. This is *not* intended for production environments and is designed for testing purposes only. Please report any defects via the Samba bug reporting system at https://bugzilla.samba.org/. Samba 4.11 will be the next version of the Samba suite. UPGRADING ========= NEW FEATURES/CHANGES ==================== Default samba process model --------------------------- The default for the --model argument passed to the samba executable has changed from 'standard' to 'prefork'. This means a difference in the number of samba child processes that are created to handle client connections. The previous default would create a separate process for every LDAP or NETLOGON client connection. For a network with a lot of persistent client connections, this could result in significant memory overhead. Now, with the new default of 'prefork', the LDAP, NETLOGON, and KDC services will create a fixed number of worker processes at startup and share the client connections amongst these workers. The number of worker processes can be configured by the 'prefork children' setting in the smb.conf (the default is 4). Authentication Logging. ----------------------- Winbind now logs PAM_AUTH and NTLM_AUTH events, a new attribute "logonId" has been added to the Authentication JSON log messages. This contains a random logon id that is generated for each PAM_AUTH and NTLM_AUTH request and is passed to SamLogon, linking the windbind and SamLogon requests. The serviceDescription of the messages is set to "winbind", the authDescription is set to one of: "PASSDB, , " "PAM_AUTH, , " "NTLM_AUTH, , " where: is the name of the command makinmg the winbind request i.e. wbinfo is the process id of the requesting process. The version of the JSON Authentication messages has been changed to 1.2 from 1.1 REMOVED FEATURES ================ smb.conf changes ================ Parameter Name Description Default -------------- ----------- ------- KNOWN ISSUES ============ https://wiki.samba.org/index.php/Release_Planning_for_Samba_4.11#Release_blocking_bugs ####################################### Reporting bugs & Development Discussion ####################################### Please discuss this release on the samba-technical mailing list or by joining the #samba-technical IRC channel on irc.freenode.net.
