NT4-style replication based net commands removed
|
||||
------------------------------------------------
|
||||
|
||||
The following commands and sub-commands have been removed from the
|
||||
"net" utility:
|
||||
|
||||
net rpc samdump
|
||||
net rpc vampire ldif
|
||||
|
||||
Also, replicating from a real NT4 domain with "net rpc vampire" and
|
||||
"net rpc vampire keytab" has been removed.
|
||||
|
||||
The NT4-based commands were accidentially broken in 2013, and nobody
|
||||
noticed the breakage. So instead of fixing them including tests (which
|
||||
would have meant writing a server for the protocols, which we don't
|
||||
have) we decided to remove them.
|
||||
|
||||
For the same reason, the "samsync", "samdeltas" and "database_redo"
|
||||
commands have been removed from rpcclient.
|
||||
|
||||
"net rpc vampire keytab" from Active Directory domains continues to be
|
||||
supported.
|
||||
|
||||
vfs_aio_linux module removed
|
||||
----------------------------
|
||||
|
||||
The current Linux kernel aio does not match what Samba would
|
||||
do. Shipping code that uses it leads people to false
|
||||
assumptions. Samba implements async I/O based on threads by default,
|
||||
there is no special module required to see benefits of read and write
|
||||
request being sent do the disk in parallel.
|
||||
|
||||
smbclient reparse point symlink parameters reversed
|
||||
---------------------------------------------------
|
||||
|
||||
A bug in smbclient caused the 'symlink' command to reverse the
|
||||
meaning of the new name and link target parameters when creating a
|
||||
reparse point symlink against a Windows server. As this is a
|
||||
little used feature the ordering of these parameters has been
|
||||
reversed to match the parameter ordering of the UNIX extensions
|
||||
'symlink' command. The usage message for this command has also
|
||||
been improved to remove confusion.
|
||||
|
||||
Winbind changes
|
||||
---------------
|
||||
|
||||
The dependency to global list of trusted domains within
|
||||
the winbindd processes has been reduced a lot.
|
||||
|
||||
The construction of that global list is not reliable and often
|
||||
incomplete in complex trust setups. In most situations the list is not needed
|
||||
any more for winbindd to operate correctly. E.g. for plain file serving via SMB
|
||||
using a simple idmap setup with autorid, tdb or ad. However some more complex
|
||||
setups require the list, e.g. if you specify idmap backends for specific
|
||||
domains. Some pam_winbind setups may also require the global list.
|
||||
|
||||
If you have a setup that doesn't require the global list, you should set
|
||||
"winbind scan trusted domains = no".

||||
|
||||

||||
REMOVED FEATURES
|
||||
================
|
||||
|
||||
The two commands 'net serverid list' and 'net serverid wipe' have been
|
||||
removed, because the file serverid.tdb is not used anymore.
|
||||
|
||||
'net serverid list' can be replaced by listing all files in the
|
||||
subdirectory "msg.lock" of Samba's "lock directory". The unique id
|
||||
listed by 'net serverid list' is stored in every process' lockfile in
|
||||
"msg.lock".
|
||||
|
||||
'net serverid wipe' is not necessary anymore. It was meant primarily
|
||||
for clustered environments, where the serverid.tdb file was not
|
||||
properly cleaned up after single node crashes. Nowadays smbd and
|
||||
winbind take care of cleaning up the msg.lock and msg.sock directories
|

automatically.
