Hi,
I'm trying to set up MemCacheTicketRegistry but I am facing some issue
and I can't really see what is going on. I have seen older Pull
Request/JIra issue saying that this problem is solved but I can see in
my logs some differences.
I use CAS 4.0.0 and followed all the steps on the CAS doc : see here
<https://jasig.github.io/cas/4.0.0/installation/Memcached-Ticket-Registry.html>
My CAS is configured to use remember me credential and the user are
loaded from our LDAP server.
To get a better idea of what my problem is I will paste my cas log below.
Thanks in advance !
Germain
