The scheduled update (ADV190023), regarding LDAP Signing and Channel Binding for new and existing domain controllers, scheduled for March 10, 2020, has been postponed to the second half of calendar year 2020. The March 2020 update will only provide additional auditing capabilities to identify and configure LDAP systems before they become inaccessible with the later update.
The later update results in no more connections to the domain controller, via unsigned / Clear Text LDAP on port 389. Then it is only possible to use either LDAPS via port 636 or Signed LDAP (StartTLS) on port 389.Continue reading “ADV190023 – Enable LDAPS in Windows DC and Citrix ADC”
In the past months, I have had to deploy Microsoft Teams and OneDrive from the Office365 portfolio in Citrix environments, in addition to the standard office applications in numerous projects.
The standard installation, that the user can perform through the Office365 portal, is a user-based installation. In a Citrix environment, this is only recommended for desktop operating systems (pooled or personal desktop).
In order for Teams to function in server operating systems (multi-user capable), the Machine Based Installer must be used. In this case, part of the data is stored in the folder C:\%PROGRAMFILES%\Microsoft\Teams. However, Teams can no longer be updated automatically as soon as a new version is available. This mode is recommended for non-persistent environments.Continue reading “Install Teams & OneDrive in Citrix (Machine-Based)”
