Let us focus on the user in this case.
I am a user.
Please give me the guidance what debug level I should use.
I general high level instruction will be good enough.
I want to troubleshoot a problem, what level should it use?
9? 10? Bit mask? If I do 7 is it enough?
Should I just always use the highest so that you get everything once?
Going several rounds is probably the most annoying thing.
I would recommend to use
debug_level = 7.
It is not simple to read log files therefore I would also recommend to filter
the most critical errors from obtained log files.
grep -E "(0x00[1-9])" sssd_sth.log
If it does not help then you need to find wider context around problematic
debug messages obtained from grep.
