Hello, we saw the same issue and I filed https://bugzilla.samba.org/show_bug.cgi?id=11416 for that. A variable had not been initialized in the C code. This has been fixed in the Samba master branch quite a while ago but the patch has not been merged to the v4-2-stable branch yet. Cheers, Arvid Am Freitag, 22.
