-Subject: Basic DCE/DFS Support for SAMBA 1.9.13
-=============================================================================
-
-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/
-
-
-
-Bugs, Suggestions, etc..
---------------------------
-
- 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.
