Marcel created ZEPPELIN-4887:
--------------------------------
Summary: Ldap Integration for ActiveDirectory (principal argument
cannot be null)
Key: ZEPPELIN-4887
URL: https://issues.apache.org/jira/browse/ZEPPELIN-4887
Project: Zeppelin
Issue Type: Bug
Components: conf, zeppelin-server
Affects Versions: 0.8.2, 0.9.0
Environment: Active Directory and Zeppelin 0.8.2 (also tested with
0.9Preview)
Reporter: Marcel
Attachments: shiro-exa.ini
We are currently configuring Zeppelin against an ActiveDirectory. According to
the documentation we have created the following Shiro.ini configurations. The
login and the assignment of roles works. However, we receive an error message
every time you login. We have the problem that our ActiveDirectory users are
not all in one OU as is the case with most LDAP implementations. Therefore we
cannot use DN templates, e.g. for group membership.
