Samba 4.4 rc1 发布，部分更新如下：
UPGRADING ========= Nothing special. NEW FEATURES/CHANGES ==================== Asynchronous flush requests --------------------------- Flush requests from SMB2/3 clients are handled asynchronously and do not block the processing of other requests. Note that 'strict sync' has to be set to 'yes' for Samba to honor flush requests from SMB clients. s3: smbd -------- Remove '--with-aio-support' configure option. We no longer would ever prefer POSIX-RT aio, use pthread_aio instead. samba-tool sites ---------------- The 'samba-tool sites' subcommand can now be run against another server by specifying an LDB URL using the '-H' option and not against the local database only (which is still the default when no URL is given). samba-tool domain demote ------------------------ Add '--remove-other-dead-server' option to 'samba-tool domain demote' subcommand. The new version of this tool now can remove another DC that is itself offline. The '--remove-other-dead-server' removes as many references to the DC as possible. samba-tool drs clone-dc-database -------------------------------- Replicate an initial clone of domain, but do not join it. This is developed for debugging purposes, but not for setting up another DC. pdbedit ------- Add '--set-nt-hash' option to pdbedit to update user password from nt-hash hexstring. 'pdbedit -vw' shows also password hashes. smbstatus --------- 'smbstatus' was enhanced to show the state of signing and encryption for sessions and shares. s4-rpc_server ------------- Add a GnuTLS based backupkey implementation. ntlm_auth --------- Using the '--offline-logon' enables ntlm_auth to use cached passwords when the DC is offline. Allow '--password' force a local password check for ntlm-server-1 mode. vfs_offline ----------- A new VFS module called vfs_offline has been added to mark all files in the share as offline. It can be useful for shares mounted on top of a remote file system (either through a samba VFS module or via FUSE). KCC --- The Samba KCC has been improved, but is still disabled by default.
Samba， 是种自由软件，用来让UNIX系列的操作系统与微软Windows操作系统的SMB/CIFS（Server Message Block/Common Internet File System）网络协定做连结。在目前的版本（v3），不仅可存取及分享SMB的资料夹及打印机，本身还可以整合入Windows Server的网域、扮演为网域控制站（Domain Controller）以及加入Active Directory成员。简而言之，此软件在Windows与UNIX系列OS之间搭起一座桥梁，让两者的资源可互通有无。
