Handling database errors

[Manuel Haim]

Hi list,

I am running an IdP 3.3.1 with shibboleth.JPAStorageService enabled (for
idp.session, idp.consent and idp.artifact).

However, if I switch off the database server, I can see several errors
(javax.persistence.PersistenceException) within idp-process.log, but no
errors are shown to the user during his/her login attempts. The user can
authenticate, but an empty attribute set is passed to the SP.

Is there a predefined way to terminate the IdP flow on database errors
(and showing an error message to the user)? Or do I have to insert e.g.
a context-check interceptor myself?

Kind regards,
Manuel
