cas-management doesn't access to my json directory

[Didier Capdevielle]

Hello everybody,
(Sorry for my english)

I have a problem reading my JSON directory. Maybe i do not understand how it works.

When i installed Cas Server (4.2.7), i use JSON as Service Management and change the directory of JSON Files (i can't create new JSON files on existing directory, by default).
My new directory is /etc/cas/json

After that, i installed cas-management webapp (5.0.x) on the same server and it works fine BUT reading JSON files are those which are in the default directory

In /etc/cas/config/management.properties, i add : service.registry.config.location=file:/etc/cas/json but without success.
I don't find other way. I try other syntax. Stille reading the same.

How to make cas-management reading my directory ? 

Thanks in advance,

Best regards,
