Hi, Didier. We're also experiencing some WebProxy and ClearPass issues with CAS 
5.2.x and uPortal 4. What version of uPortal are you running?

thanks,
Luke

OK, I answer by myself.
Found the solution by a colleague in a French list. Thanks a lot to him.
I try to explain (sorry for my english) :
Problem is in our UPortal behind a web front-end server. We have to add 
allowedProxyChains parameter in the web.xml of UPortal.
CAS Server 5.2.x needs this parameter (CAS Server 5.1.x NO).
Thanks
Best regards

Hello CAS' Experts,
We have trouble using Proxy Mode (for UPortal) with CAS Server 5.2.x.
SAME server (Debian Stretch ; OpenJDK 8 ; Tomcat8) and SAME configuration 
(except json-service-registry dependency and json location directory : 
different names). SAME Json files.
5.1.7 / 5.1.8 : NO problem with proxy mode (CAS 2 protocol)
