'Samba4 TP4' presents you with an opportunity to see a Technology
|
|
Preview (TP) snapshot of Samba4's development, as at January 2007.
|
|
|
|
In the last few months since TP3 was released in October 2006,
|
|
significant work has been done across many parts of Samba4. Since that
|
|
time, we have added the basis for some new and exciting features:
|
|
|
|
PKINIT support to Samba4's KDC will allow, smart-card login to a
|
|
Samba4 domain. TP4 demonstrates this with static key files, but
|
|
work will continue to enable actual hardware cards.
|
|
|
|
Clustering support was always a design goal of Samba4, and with TP4
|
|
we have the ctdb framework, a cluster-aware shared database. This
|
|
allows Samba4 to share a shared cluster file-system with it's clients.
|
|
Presented at this year's linux.conf.au, including a highly rigged
|
|
demo, you can expect to see this mature over the next few months.
|
|
|
|
Non-blocking and Asynchronous IO support, has always been a design
|
|
goal in Samba4, and TP4 will use new Linux Kernel features to
|
|
implement event driven asynchronous IO. This makes Samba more
|
|
efficient on systems where some data may be 'further away' than a
|
|
local disk, such as HSM systems. This allows the Kernel to handle
|
|
reading the returned data from the disk, only notifying Samba when
|
|
the data is ready for dispatch to the client.
|
|
|
|
Our web-management console, known as SWAT, is being revamped, and in
|
|
TP4 you can find a new Web 2.0 style user interface, being used to
|
|
support a web-based ldb browser. We hope this new system will allow
|
|
things simple not possible with the form-submit style of web
|
|
management.
|
|
|
|
Using LDB LDAP back-end integration has improved in this release, with an
|
|
improved mapping module allowing the start of Fedora DS back-end
|
|
support.
|
|
|
|
In continuing our research effort, TP4 includes the work to better
|
|
understand and implement the DRSUAPI replication protocols. By better
|
|
understanding the needs of replication now, we can structure our
|
|
databases so that their format will have to change less in future.
|
|
|
|
We hope to use this replication function to replace the SamSync based
|
|
Vampire process so effectively demonstrated since TP1, and to
|
|
eventually join an Active Directory domain, as a replicating partner.
|
|
|
|
Behind the scenes, much of the core infrastructure of Samba4 continues
|
|
development:
|
|
|
|
In Kerberos, we have continued to track the development of the
|
|
Heimdal Kerberos implementation, and reduce the custom diff between
|
|
our branch and upstream. Heimdal now provides plug-in APIs for
|
|
almost all of the hooks we need, including management and validation
|
|
of the PAC.
|
|
|
|
In testing, our test infrastructure has undergone a quiet
|
|
revolution, as we improve our unit test framework. Likewise, the
|
|
tests themselves have continued to expand, as we follow our
|
|
test-driven development pattern.
|
|
|
|
In providing an abstraction above our raw RPC layer, the libnet
|
|
library continues to expand, becoming a C and JS management API for
|
|
Samba4 and remote servers.
|
|
|
|
To ensure that, as an administrator and developer, you can easily
|
|
read and edit our internal databases, our LDB layer has been
|
|
optimised for speed. The aim here is to avoid needing to use the faster, but
|
|
more opaque, TDB layer.
|
|
|
|
These are just some of the highlights of the work done in the past few
|
|
months. More details can be found in our SVN history.
