Shibboleth IdP 4.0.1 and CAS

[Max]

Hi all,

After upgrading our Shibboleth IdP from v3.4.8 to v4.0.1 the CAS requests no 
longer work.

When we ask for a CAS resource (/cas/login?service=http://mysite.ch/) Tomcat 
9.0.40 answers with a "404 - Not Found" message.
It seems that the /cas and /sCAS Context Roots are no longer present.

In the file %{idp.home}/conf/services.xml the CASServiceRegistryResources is 
enabled:
   <util:list id="shibboleth.CASServiceRegistryResources">
   <value>%{idp.home}/conf/cas-protocol.xml</value>
   </util:list>

File %{idp.home}/conf/cas-protocol.xml is the same as file 
%{idp.home}/dist/conf/cas-protocol.xml.

These are the entries we have in the idp-process.log file related to CAS 
during startup:
   Service 'shibboleth.ReloadableCASServiceRegistry': Performing initial 
load
   Service 'shibboleth.ReloadableCASServiceRegistry': Reloading service 
configuration
   Service 'shibboleth.ReloadableCASServiceRegistry': Completed reload and 
swapped in latest configuration for service 
'shibboleth.ReloadableCASServiceRegistry'
   Service 'shibboleth.ReloadableCASServiceRegistry': Reload complete
   Service 'shibboleth.ReloadableCASServiceRegistry': Reload interval set 
to: PT15M, starting refresh thread

Any help is much appreciated.

Best Regards,
Max
