• CVE-2020-10730: Fixed a null de-reference in AD DC LDAP server when ASQ and VLV combined (bsc#1173159).
• CVE-2020-10760: Fixed a use-after-free in AD DC Global Catalog LDAP server with paged_result or VLV (bsc#1173161).
• Added libnetapi-devel to baselibs conf, for wine usage (bsc#1172307).
• Fixed an installing issue where samba - samba-ad-dc.service did not exist and unit was not found (bsc#1171437).
