In particular, one of the fixes introduced in samba 4.3.7 was to properly check certificates, as @mdeslaur said in comment #2:
"o CVE-2016-2113 (Missing TLS certificate validation)" So I would ask you to double check your certificates and chain to make sure all is correct in that front, as samba would have skipped some validation checks before. ** CVE added: https://cve.mitre.org/cgi-bin/cvename.cgi?name=2016-2113 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1576799 Title: Regression: 2:4.3.8+dfsg-0ubuntu0.14.04.2 Failed to Issue the StartTLS instruction To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1576799/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
