[ https://issues.apache.org/jira/browse/DIRSERVER-1567?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Kiran Ayyagari updated DIRSERVER-1567:
--------------------------------------
Assignee: Kiran Ayyagari
Summary: NPE in AuthenticationInterceptor while doing anonymous bind (was: Anonymous bind fails with an 'Unexpected exception' message)
When a anonymous bind is performed and PPolicy is enabled then AuthenticationInterceptor tries to perform ppolicy checks and this results in a NPE (the user entry will be null cause of the empty dn)

> When I attempt to bind as anonymous using the current trunk, I get rejected with an InvalidCredentials Ldap Error (code 49) and a strange message 'Unexpected exception'.
> I dug a bit the problem and found out an NPE in the AuthenticationInterceptor was the cause of the 'Unexpected exception'.
> Here's the full stacktrace of the NPE:
