Subject [jira] [Commented] (OAK-256) JAAS Authentication failing in OSGi env due to classloading issue
Date Tue, 04 Sep 2012 18:25:09 GMT

    [ https://issues.apache.org/jira/browse/OAK-256?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13447896#comment-13447896

Michael Dürig commented on OAK-256:
-----------------------------------

The TCCL approach won't work reliably I think. We should eventually come up with a more reliable
solution. See also http://www.slideshare.net/mfrancis/common-security-services-consolidation-patterns-for-legacy-components-stefan-vladov
