Hi!

I upgraded from CAS 6.1.x to 6.5.9 and got that to run with little trouble (apart from per-Service-CORS).

Now I am getting reports that people cannot log in to a SAML-service and looking in the log, I see

java.lang.IllegalArgumentException: SAML request or context could not be determined from session store

My setup is

HA-Proxy->2 tomcats->REDIS Sentinel.

The proxy is only balancing and setting cookies while the sentinel is of course identical for both tomcats, just as their crypto-setup (which i did not change from 6.1).

I stumbled across a similar problem of another CAS-User and proceeded to set

cas.authn.saml-idp.core.session-storage-type=TICKET_REGISTRY

Alas, that did not really work either.

Then i deactivated one of the tomcats to check if there is voodoo happening if requests are checked by a different tomcat than the one issuing them.

Did not change the errors.

Since there is no hint in the error (the exception is not very helpful..), I wonder if anyone out there has similar trouble and can enlighten me.

Best regards,

Sven Specker
