I've retested the patches again with SSSD git head + the patches on review and
freeipa-server-2.1.3-2 I've performed about 20 migrations (scripted) and
they went OK.
Attached are patches that are rebased on current master. Because the
migration patch touches most of the ipa-auth.c file I've also fixed the
debug levels there.
