[jira] [Commented] (OAK-256) JAAS Authentication failing in OSGi env due to classloading issue

["Chetan Mehrotra (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OAK-256?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13447863#comment-13447863 ] 

Chetan Mehrotra commented on OAK-256:
-------------------------------------

As noted in previous comment I tried to use the same approach however it fails for those calls where impersonation is performed as in Session#impersonate. As by the time that call is done TCCL would have been reverted back. 

I am not sure of a better approach. Probably in OSGi env we can have a custom LoginContextProvider which handles it better. However untill then I cannot workaround it from outside
