> Key: NXP-4655
> URL: https://jira.nuxeo.org/browse/NXP-4655
> Project: Nuxeo Enterprise Platform
> Issue Type: Bug
> Components: Web UI
> Affects Versions: 5.3 GA
> Environment: Ubuntu server (32 bit) using sun-java-5-jre version
> 1.5.0-20-0ubuntu0.8.04 with JBoss, and an Apache frontend performing
> authentication, using AJP for Apache to Nuxeo communication.
> Reporter: Gregory Wolgemuth
> Priority: Major
>
> Nuxeo DM 5.3GA is configured with the proxy_auth plugin, authenticating from
> an HTTP header injected by an Apache frontend.
> When a user without a current session (i.e. browser is closed, no cookies)
> follows a link deep into Nuxeo DM (e.g. a link to the history view of a
> document, or the comments list of a document) they are given an error page
> instead of the linked content. If the user follows the same steps, but with
> an existing Nuxeo session, the content displays as expected.
> Following is the stack trace found in the Nuxeo log:
> java.lang.NullPointerException
