Known Issues IGEL UMS 12.08.130

UMS Common

• AD logon will fail in an environment where the Domain Name System (DNS) cannot map to Key Distribution Centers (KDCs). This mapping is crucial for the UMS to locate the KDC responsible for a specific realm when authenticating.

Firmware Update of OS 11 versions

OS 11 devices with only a small amount of free space on the disc are using a multi-reboot workflow for an OS 11 firmware update. This workflow is broken if the UMS has version 12.08.xx. As a result, these devices will enter an infinite boot loop.
If you have devices with low disc space, either:

• update the devices before switching to UMS 12.08.xx if you have UMS 12.07.xx or lower installed.

• test with single devices before updating a larger number of devices. If your devices are affected, update to UMS 12.09.100 or higher before updating the device firmware.

• use an alternative source for firmware update instead of UMS (for example, external WebDAV or FTP).

Affected environments:

• UMS versions 12.08.100, 12.08.110, 12.08.120, 12.08.130

• Firmware update of any OS 11 version
