12 Per-instance authentication for DCE/DFS.
14 Missing Functionality in this Implementation:
15 ---------------------------------------------
17 * No automatic refresh of credentials
19 To do so would not be that hard.. One could simply
20 stash the clear-text key in memory, spawn a key management
21 thread to wake up right before credentials expire and
22 refresh the login context.
24 * No UNIX Signals support (SIGCLD, SIGPIPE, SIGHUP, SIGBUS, SIGSEGV)
27 There is no support for signal processing in Samba daemons
28 that need to authenticate with DCE. The explanation for this
29 is that the smbd is linked against thread-safe libraries in
30 order to be able to use DCE authentication mechanisms.
31 Because smbd uses signal() and fork(), it represents the
32 worst case scenario for DCE portability. In order
33 to properly support signals in a forked server environment,
34 some rework of smbd is needed in order to properly
35 construct, shutdown and reconstruct asynchronous signal
36 handling threads and synchronous signal traps across the
37 parent and child. I have not had contiguous time to work
38 on it, I expect it to be a weeks worth of work to cleanly
39 integrate thread-safe signal handing into the code and
40 test it. Until I can get to this task, I will leave it up
41 to someone adventurous enough to engineer it and negotiate
42 with Andrew to integrate the changes into the mainline branch.
44 The lack of full signal support means that you cannot
45 rely upon SIGHUP-ing the parent daemon to refresh
46 the configuration data. Likewise, you cannot take advantage
47 of the builtin SIGBUS/SIGSEGV traps to diagnose failures.
48 You will have to halt Samba in order to make changes
49 and then have them take effect.
51 The SMBD server as it stands is suitable to use if you
52 already have experience with configuring and running
58 HP-UX 9.05 / HP-UX DCE 1.2.1
59 AIX 3.2.5 / AIX DCE/6000 1.3
60 DEC OSF-1 3.0 / DEC DCE 1.3
65 - Uncomment the the appropriate block in the Makefile
66 for the platform you wish to build on.
68 - Samples of Samba server configuration files for our
69 DFS environment are included in samples.dcedfs/

77 That way I will see them and they will become part of
78 the archives so others can share the knowledge.
