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. + |
