Summary

Microsoft intends to release a security update to add options for administrators to harden the configurations for LDAP channel binding on Active Directory domain controllers. This update is set to be available in March 2020. If administrators make the hardening changes, Microsoft Active Directory server will reject LDAP simple binds.

Mobile Security for Enterprise customers using None as Encryption Type will be affected by this change. Customers should change the Active Directory Settings to LDAP over SSL or LDAP startTLS before applying the Microsoft security update.
