Hi guys, I spent some time working at this ticket
https://fedorahosted.org/sssd/ticket/1108 and I think it's finally
ready to be reviewed by others.
Description of the problem and scope of the changes can be found in
the commit message. I also wrote some unit tests but the patch is a
quite long already so I think it would be better to send the tests as
an another patch. Or should I create a patch for each modified file?
Package sssd_220.127.116.11-1 on Debian FTBFS for mips and mipsel.
dyndns_test_ok is failing with following log:

I have created and attached a patch which is workaround for this issue.
Could someone please take a look and comment this?
one of our users ran into an interesting problem -- her AD
infrastructure was different from the DNS server. Because by default, we
perform update against the server we're connected to, the DNS update
Per Simo's suggestion, I've implemented a new option that allows the
administrator to override the DNS server used for DNS updates.
for past few days, I've been working on python3-compat patch for sssd. The patch  is attached to the issue that requests this feature .
- The patch tries to maintain backward compatibility for Python 2.6 and 2.7 - I admit I only tested 2.7 so far, but it seemed to work ok.
- I didn't yet solve the build part - for now, I just handedit configure.ac to set "PYTHON=python3" and src/external/python.m4 to set "AC_PATH_PROG(PYTHON, python3)" and compile with that.
- I managed to run Python tests in src/tests except python-test.py itself (it says "OSError: [Errno 5] Could not initialize connection to the confdb" and I didn't yet investigate why that happens).
- To run tests, one must modify the hashbangs to /usr/bin/python3 (I now see that I left one of these in the actual patch, so please disregard that).
I'd like to ask you, sssd devels, to give me some comments on the patch (or ask questions) and if you have some time to spare, doing more extensive testing would also be very welcome.

While checking if our custom signal handlers properly handle errno, I
stumbled on a few cleanups, they are attached.
turns out our few signal hanlders are errno safe, and tevent signal
handling function is also fine.

I noticed that if using simple access provider and having non-existing
group or user in access/deny list then access will be denied and "su:
System error" will be printed.
I think it's OK to simply skip non-existing objects on allow_list.
I'm not so sure what to do in case of deny lists. Should we also just
skip them or should we deny the user and print more appropriate message
("su: Permission denied")?
Extensive travel in recent months allowed me to finish this code.
Here is the updated design:
0001 - Fix in case the Ref array is empty and we need to print/debug it
0002 - Declaration of the new function to do access checks
0003 - Big patch with core functionality
0004 - Updated access check code to use new internal access control function
0005 - File with expected output for unit test validation
0006 - Makefile and related changes to start building new code

yet another warning from clang static analyser.
sss_krb5_princ_realm set output parameter realm to NULL and len to 0
in case of failure. Clang static analysers repoted warning
"Null pointer passed as an argument to a 'nonnull' parameter"
in function match_principal. It was possible, that realm_name with value NULL
could be used in strncmp.
Function sss_krb5_princ_realm is used on other places for printing(formatting)
realm_name and NULL can be safely used as a argument for printf-like
Patch is attached.
