      Jenkins version: 2.282
      saml-plugin version: 2.0.0
    • saml-2.0.3

      After upgrading to 2.0.0, when users are redirected back to `/securityRealm/finishLogin ` the following exception is thrown:

      WARNING o.e.j.s.h.ContextHandler$Context#log: Error while serving http://jenkins.domain/securityRealm/finishLogin

      However if you continue into Jenkins, the user is authenticated and can browse freely. It will happen every time a user needs to be re-authenticated.
