Hello,
I am trying to use CAS as an identity provider for google apps. So I have
followed the steps described at
https://apereo.github.io/cas/5.0.x/integration/Google-Apps-Integration.html
However, I am having an error when trying to access a google apps service
where cas throw an exception even before I had a chance to authenticate...
The full stacktrace is below, but in summary there seems to be a problem to
serialize org.apereo.cas.support.saml.OpenSamlConfigBean...
I think that the google apps integration is properly configured, I can see
the following in the logs at startup:
2017-01-24 11:28:08,778 DEBUG

Any idea what could be wrong?
Cheers
