Hi Folks,
if you got issues with SHA2 certificates in the past and if used together with a Citrix environment you should try the latest IGEL 5.04.100 LX/OS firmware.
The new firmware contains a updated Citrix Receiver 13 version which comes now with SHA2 certificate support, important here: You must use the Citrix Receiver 13, no option to use Receiver Version 12 here! So it might be that you have to reconfigure your thin clients to work together with your environment and to get Receiver 13 to work.
Please test the new configuration in advance, do not just modify it to see what happens for all your users (otherwise they will hate you). 😉
Cheers
Michael
