The autobuild test system (on sn-devel-144) has detected an intermittent failing test in 
the current master tree.

The autobuild log of the failure is available here:

The failure seems to be in the "samba-py3" suite, whose build logs are available here:
The top commit at the time of the failure was:

commit 188541076a1a19acb8a3dd572a5bd4f69350cf41

    selftest: Tweak PSO test-suite name
    There are 2 different PSO tests:
    - make test TESTS=ldap.password_settings
    - make test TESTS=samba_tool.passwordsettings
    There's also another test that's completely unrelated to PSOs:
    - make test TESTS=blackbox.password_settings
    This patch renames ldap.password_settings --> ldap.passwordsettings.
    This means 'make test TESTS=passwordsettings' will run both PSO tests,
    but not the unrelated blackbox test.
