40 WHATS NEW IN Samba 2.2.0
41 ========================
43 This is the official Samba 2.2.0 release. This version of Samba provides
44 the following new features and enhancements.
46 Integration between Windows oplocks and NFS file opens (IRIX and Linux
47 2.4 kernel only). This gives complete data and locking integrity between
48 Windows and UNIX file access to the same data files.
50 Ability to act as an authentication source for Windows 2000 clients as
51 well as for NT4.x clients.
53 Integration with the winbind daemon that provides a single
54 sign on facility for UNIX servers in Windows 2000/NT4 networks
55 driven by a Windows 2000/NT4 PDC. winbind is not included in
56 this release, it currently must be obtained separately. We are
57 committed to including winbind in a future Samba 2.2.x release.
59 Support for native Windows 2000/NT4 printing RPCs. This includes
60 support for automatic printer driver download.
62 Support for server supported Access Control Lists (ACLs).
63 This release contains support for the following filesystems:
67 Linux Kernel with ACL patch from http://acl.bestbits.at
68 Linux Kernel with XFS ACL support.
71 FreeBSD (with external patch)
73 Other platforms will be supported as resources are
74 available to test and implement the encessary modules. If
75 you are interested in writing the support for a particular
76 ACL filesystem, please join the samba-technical mailing
77 list and coordinate your efforts.
79 On PAM (Pluggable Authentication Module) based systems - better debugging
80 messages and encrypted password users now have access control verified via
81 PAM - Note: Authentication still uses the encrypted password database.
83 Rewritten internal locking semantics for more robustness.
84 This release supports full 64 bit locking semantics on all
85 (even 32 bit) platforms. SMB locks are mapped onto POSIX
86 locks (32 bit or 64 bit) as the underlying system allows.
88 Conversion of various internal flat data structures to use
89 database records for increased performance and
92 Support for acting as a MS-DFS (Distributed File System) server.
94 Support for manipulating Samba shares using Windows client tools
95 (server manager). Per share security can be set using these tools
96 and Samba will obey the access restrictions applied.
98 Samba profiling support (see below).
100 Compile time option for enabling a (Virtual file system) VFS layer
101 to allow non-disk resources to be exported as Windows filesystems
102 (such as databases etc.).
104 The documentation in this release has been updated and converted
105 from Yodl to DocBook 4.1. There are many new parameters since 2.0.7
106 and some defaults have changed.
110 Support for collection of profile information. A shared
111 memory area has been created which contains counters for
112 the number of calls to and the amount of time spent in
113 various system calls and smb transactions. See the file
114 profile.h for a complete listing of the information
115 collected. Sample code for a samba pmda (collection agent
116 for Performance Co-Pilot) has been included in the pcp
119 To enable the profile data collection code in samba, you
120 must compile samba with profile support (run configure with
121 the --with-profile option). On startup, collection of data
122 is disabled. To begin collecting data use the smbcontrol
123 program to turn on profiling (see the smbcontrol man page).
124 Profile information collection can be enabled for all smbd
125 processes or one or more selected processes. The profiling
126 data collected is the aggragate for all processes that have
129 With samba compiled for profile data collection, you may see
130 a very slight degradation in performance even with profiling
131 collection turned off. On initial tests with NetBench on an
132 SGI Origin 200 server, this degradation was not measureable
133 with profile collection off compared to no profile collection
136 With count profile collection enabled on all clients, the
137 degradation was less than 2%. With full profile collection
138 enabled on all clients, the degradation was about 8.5%.
