In August 2019 Microsoft published Security Advisory ADV190023 advising that a new set of safe default configurations for LDAP channel binding and LDAP signing on Active Directory Domain Controllers will be introduced by Windows Updates during March 2020.

In essence, the current LDAP protocol is unsafe and will be replaced by a new LDAPS protocol.

As a third-party application, Hyperion EPM implementations will be affected if Microsoft Active Directory is used for Hyperion user authentication.

Please read this bulletin and ensure you are prepared in advance.
