============================================================================= Basic DCE/DFS Support for SAMBA 1.9.13 Jim Doyle <doyle@oec.com> 06-02-95 ============================================================================= 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.
