Rebuilt with patch. Advisory doesn't contain details yet.
Comment 2 Arvid Requate univentionstaff 2016-12-13 20:54:08 CET
Another patch was added a couple of minutes ago, which hadn't been included in the upstream backport patch for Samba 4.3. The package is building again now.
Advisory is adjusted.

The patch for Bug 41729 hadn't been backport to UCS 3.3, I've included that too now. That required some shuffling with the patches because there was no space after 99_...

Package is building, Advisory is adjusted.
