Functionality:
|
|
--------------
|
|
|
|
Per-instance authentication for DCE/DFS.
|
|
|
|
Missing Functionality in this Implementation:
|
|
---------------------------------------------
|
|
|
|
* No automatic refresh of credentials
|
|
|
|
To do so would not be that hard.. One could simply
|
|
stash the clear-text key in memory, spawn a key management
|
|
thread to wake up right before credentials expire and
|
|
refresh the login context.
|
|
|
|
* No UNIX Signals support (SIGCLD, SIGPIPE, SIGHUP, SIGBUS, SIGSEGV)
|
|
|
|
|
|
There is no support for signal processing in Samba daemons
|
|
that need to authenticate with DCE. The explanation for this
|
|
is that the smbd is linked against thread-safe libraries in
|
|
order to be able to use DCE authentication mechanisms.
|
|
Because smbd uses signal() and fork(), it represents the
|
|
worst case scenario for DCE portability. In order
|
|
to properly support signals in a forked server environment,
|
|
some rework of smbd is needed in order to properly
|
|
construct, shutdown and reconstruct asynchronous signal
|
|
handling threads and synchronous signal traps across the
|
|
parent and child. I have not had contiguous time to work
|
|
on it, I expect it to be a weeks worth of work to cleanly
|
|
integrate thread-safe signal handing into the code and
|
|
test it. Until I can get to this task, I will leave it up
|
|
to someone adventurous enough to engineer it and negotiate
|
|
with Andrew to integrate the changes into the mainline branch.
|
|
|
|
The lack of full signal support means that you cannot
|
|
rely upon SIGHUP-ing the parent daemon to refresh
|
|
the configuration data. Likewise, you cannot take advantage
|
|
of the builtin SIGBUS/SIGSEGV traps to diagnose failures.
|
|
You will have to halt Samba in order to make changes
|
|
and then have them take effect.
|
|
|
|
The SMBD server as it stands is suitable to use if you
|
|
already have experience with configuring and running
|
|
SAMBA.

|
Tested Platforms:
|
|
-----------------
|
|
|
|
HP-UX 9.05 / HP-UX DCE 1.2.1
|
|
AIX 3.2.5 / AIX DCE/6000 1.3
|
|
DEC OSF-1 3.0 / DEC DCE 1.3
|
|
|
|
Building:
|
|
---------
|
|
|
|
- Uncomment the the appropriate block in the Makefile
|
|
for the platform you wish to build on.
|
|
|
|
- Samples of Samba server configuration files for our
|
|
DFS environment are included in samples.dcedfs/
|
|
|
|
|
|
|

Please post them to the mailing list.
|
|
That way I will see them and they will become part of
|
|
the archives so others can share the knowledge.
