Enhancements
AD Group Header Size Selection
The AD Group Header Size is now configurable with two available options: 8k and 4k. The default size remains set to 8k. For more details, see Configure Group Header Size.
NOTE: Customers using multibyte characters in their AD group headers with SCP version 4.7.0 & later (till 4.9.2), have the potential of facing issues such as failed user authentication, disrupted pop connectivity for those regions as total header size exceeds maximum header size limit. We have observed this for some customers only in the APAC region. For these customers, it is recommended to upgrade to 4.9.3 and select the AD Group Header size of 4K. For more details, see Troubleshooting AD Group Header Size.
NOTE: The default AD Header Group Size has remained 8K since Skyhigh Client Proxy version 4.7.0.
Skyhigh Client Proxy Support Tool (Windows only)
Skyhigh Client Proxy support tool supports Network Shell (netsh) to collect network traces and dependency on Wireshark has been removed. For more details, see Skyhigh Client Proxy Support Tool.
NOTE: Skyhigh Client Proxy Support Tool enhancement is currently supported on the Windows platform only.
NOTE: This patch release applies to the Windows platform only. This patch release does not support the upgrade of pre-release software versions, such as beta versions and POC builds. To install a production release of the software, you must first uninstall any pre-release versions. Upgrade work from older GA builds to the latest GA builds.
End-to-End Health Check (macOS only)
The End-to-End (E2E) health check enhancement monitors an endpoint to identify any failure scenarios in the SCP that may prevent it from securing that endpoint. This enhancement will help users detect insecure and non-compliant endpoints, enabling them to take necessary remedial actions. If a health check fails, the SCP will report the status as Not Redirecting (E2EHealthCheckFailed) and will automatically generate a Merlog. For more details, see End to End Health Check.
