A workaround to build is:
DEB_BUILD_OPTIONS=parallel=15 sbuild --resolve-alternatives -Adtrusty --chroot-setup-commands='echo "Package: samba-dev\nPin: version 2:4.1*\nPin-Priority: 1001\n\nPackage: libldb-dev\nPin: version 1:1.1.16-1\nPin-Priority: 1001" >> /etc/apt/preferences' sssd_1.11.5-1ubuntu3.dsc
which forces samba-dev from the release pocket. Then builds succeed, but tests fail. I haven't looked into this further.
