Hello community,
My client needs a new on-premises installation of Horizon 8, the latest version (2203/2111 as of now).
Currently, the client has Microsoft Active Directory Domain Functional Level of 2008 R2.
Unfortunately, per VMware KB 78652, for Horizon 8 (from 2006 to 2111), the lowest supported Microsoft Active Directory Domain Functional Level is 2012 R2.
https://kb.vmware.com/s/article/78652
For various reasons, it’s not possible for the client to upgrade to 2012 R2 Domain Functional Level in the near future.
I installed 2 Connection Servers 2111 (8.4.0-19446835) successfully, and they are replicating well.
Under Domains>Connection Server, the current domain is green, status is Normal, No Problems detected.
Our options seem to be:
- Leave the installation as is at Horizon 2111/2203 and hope for the best.
- We are opening a VMware support ticket to see if VMware can clarify and maybe confirm that nothing bad will happen (even though it is Unsupported).
- The configuration will be unsupported, and the client can eventually upgrade to a higher Domain Functional Level.
- Scrap Horizon 8 and install Horizon 7.10.3. Horizon 7.10.3 is the last Horizon version that officially supports Domain Functional Level of 2008 R2.
- https://docs.vmware.com/en/VMware-Horizon-7/7.10/horizon-installation/GUID-F6075DF0-9614-4A81-B27A-7...
- Horizon 7.10.3 does fix the log4j vulnerability.
- Horizon 7.10.3 is supported by Horizon Cloud Connector 2.1.2 (but not 2.2.0) — this still allows the client to use Horizon Universal Subscription license which they purchased.
- The support for 7.10 Extended Service Branch at the “Technical Guidance” phase expires 3-22-2023, which means the client can still call support for major issues.
- Hopefully, by the expiration of the “Technical Guidance” support phase on 3-22-2023, the client can eventually upgrade to a higher Domain Functional Level and then upgrade Horizon to 8.
- Upgrade to Microsoft Active Directory Domain Functional Level of 2012 R2 or higher — not possible in the near future.
Questions to the community:
- Does anyone know what Horizon 8 (2203/2111) functionality will break if using with the unsupported Microsoft Active Directory Domain Functional Level of 2008 R2 ?
- Can anyone think of other options in this situation?
Sincerely,
Yury Magalif
