Hi Andrew,
Thanks for getting back. Attempts to join the domain as an additional DC
failed for me but the Samba server was assigned a static IP and added to a
network where the Windows server presently hands out DHCP addresses, so I'm
going to guess that it's a DNS issue. I tried adding a record to DNS on the
Windows Server for the Samba server but it still wouldn't join, so at that
point I just assumed it was a provisioning issue based on the Wiki info
which tells you not to provision before joining. Any confirmation on the
DNS theory would be great but I don't have the exact error message that was
generated, so I'll deal with that later.
Forgive the long post, I'm trying to include as much potentially relevant
info as possible.
After checking and trying to clean up the Python installation with yum, I
seem to have accomplished two things:
1. Samba now throws an error during compilation and fails, unless I
configure and pass LDFLAGS in like so:
LDFLAGS="-lm -ldl -lutil" ./configure --enable-debug --enable-selftest
The compile then succeeds, but I still can't run samba-tool.
2. I'm no longer getting a Python-related segfault recorded in Messages
every 10 minutes. I had been getting this message for quite some time and
assume that it was due to a ClamAV related issue with Python since ClamAV
does a database check at that interval.
Moving on - the build was started as follows:
sh install_with_python.sh /usr/local/samba --enable-debug --enable-selftest
Here's some hopefully relevant Python-related output when compiling
v4-0-test:

During the compile, I see errors like:

I'm not sure just how significant that one is, if the code was written that
way intentionally but it appears to be in a library-related header so I'm
including it here.

After uninstalling/reinstalling Python 2.6.8 and it's dependencies with Yum,
v4-0-test now sees Python 2.6.5 during the configure but fails with the same
error.
All of this is on v4-0-test. Just as an FYI, when I checked out Master and
compiled it instead, I got:
Checking for Python version >= 2.4.2
: ok 2.6.5 (instead of 2.6.8 - and this was before the reinstall of 2.6.8)
in the Python config section, so it appears to be referencing the included
private build of Python instead of 2.6.8 but the compile of Master still
fails but in a different way as follows:
'configure' finished successfully (1m37.119s)

So while everything else seems to be working on this box it seems to me that
there's some issue with the Python environment that Samba doesn't like,
although I'm not quite sure what it is. I just don't know enough (anything,
really) about Waf to intelligently track down the problem.
On the initial installation attempt of Samba 4 I was having problems getting
the install_with_python script to download the file... I don't remember the
details of what was wrong now but I had to download the file manually to do
the install and I was manually compiling Python and other stuff to try to
get it to work so I may very well have messed things up during that process.
I was still having some strange issues with the same script later too so I
finally did a make uninstall and wiped out and re-cloned the source tree.
After doing that, the install script seems to be working as expected now, at
least.
Let me know if you need any additional info and I'll try to get it to you as
soon as possible.
Thanks again,
- Phil
