4 This is the first preview release of Samba 4.11. This is *not*
5 intended for production environments and is designed for testing
6 purposes only. Please report any defects via the Samba bug reporting
7 system at https://bugzilla.samba.org/.
9 Samba 4.11 will be the next version of the Samba suite.
19 Default samba process model
20 ---------------------------
22 The default for the --model argument passed to the samba executable has changed
23 from 'standard' to 'prefork'. This means a difference in the number of samba
24 child processes that are created to handle client connections. The previous
25 default would create a separate process for every LDAP or NETLOGON client
26 connection. For a network with a lot of persistent client connections, this
27 could result in significant memory overhead. Now, with the new default of
28 'prefork', the LDAP, NETLOGON, and KDC services will create a fixed number of
29 worker processes at startup and share the client connections amongst these
30 workers. The number of worker processes can be configured by the 'prefork
31 children' setting in the smb.conf (the default is 4).
33 Authentication Logging.
34 -----------------------
36 Winbind now logs PAM_AUTH and NTLM_AUTH events, a new attribute "logonId" has
37 been added to the Authentication JSON log messages. This contains a random
38 logon id that is generated for each PAM_AUTH and NTLM_AUTH request and is passed
39 to SamLogon, linking the windbind and SamLogon requests.
41 The serviceDescription of the messages is set to "winbind", the authDescription
43 "PASSDB, <command>, <pid>"
44 "PAM_AUTH, <command>, <pid>"
45 "NTLM_AUTH, <command>, <pid>"
47 <command> is the name of the command makinmg the winbind request i.e. wbinfo
48 <pid> is the process id of the requesting process.
50 The version of the JSON Authentication messages has been changed to 1.2 from 1.1
60 As a leftover from work related to the Samba Web Administration Tool (SWAT),
61 Samba still supported a Python WSGI web server (which could still be turned on
62 from the 'server services' smb.conf parameter). This service was unused and has
63 now been removed from Samba.
