* Test Windows SDDL handling.
*
* Copyright (c) 2023 Douglas Bagnall <dbagnall@samba.org>
*
* GPLv3+.
*
* This can be compiled on Windows under Cygwin, like this:
*
*
* gcc -o windows-sddl-tests windows-sddl-tests.c \
* C:/Windows/System32/advapi32.dll -ladvapi32
*
*
* then run like this:
*
* ./windows-sddl-tests.exe
*
*
* That will show you a mix of success and failure.
*
* To run the tests in python/samba/tests/sddl.py, edit the method
* _test_write_test_strings(), removing the leading underscore so it starts
* with "test_". Then running
*
* make test TESTS='sddl\\b'
*
* will write some files into /tmp, containing lines like this:
*
* D:(A;;GA;;;RU) -> D:(A;;GA;;;RU)
*
* Copy these files to Windows. Then in Cygwin, run this:
*
* ./windows-sddl-tests.exe -i non_canonical.txt canonical.txt [...]
*
* and the part of each line before the " -> " will be fed into the SDDL
* parser, and back through the serialiser, which should result in the string
* after the " -> ". These are the tests that sddl.py does.
