Hello,

We are using CAS Server 4.2.6 for few weeks now but we’re facing a problem with 
the SSO lifetime.

The ticket registry used is EhCache and the RememberMe feature is enabled, you 
can find the settings in this gist : 

<https://gist.github.com/vhurteve/af4a563645a7eaf131ccc9772c4f312a 
<https://gist.github.com/vhurteve/af4a563645a7eaf131ccc9772c4f312a>>

We would like default TGT lifetime of 12 hours (43200s) and a rememberMe of 7 
days (604800s)

SSO works but it doesn’t last as expected, forcing users to reauthenticate. The 
SSO lifetime seems random and barely 2 hours long.

I tried the neverExpire policy but I still have the problem. I tried to 
investigate the problem logging EhCache in debug mode but there’s no message 
about forced eviction or something like this. I choosed large ehcache settings, 
enough memory settings, with disk overflow, but no amelioration.

The TGT, ST, TGC settings are set in a cas.properties file correctly loaded by 
the server as the other settings (ldap servers, ehcache, encryption, etc) are 
well applied.

Where could be the problem ?

Bonus question, the TGT seems linked to username/Client IP/UserAgent, which is 
not the behavior in version 3.5.x I think where the IP didn’t come into the 
equation.
As the users are more and more moving and switching network settings, it could 
be a problem. How I can link the TGT to username and UA only ?

Thank you,
