             Summary: Ranger fails to start when using (core) LDAPGroupMapping - missing class
                 Key: RANGER-2082
                 URL: https://issues.apache.org/jira/browse/RANGER-2082
             Project: Ranger
          Issue Type: Bug
          Components: admin, Ranger
    Affects Versions: 1.0.0
            Reporter: Sailaja Polavarapu
            Assignee: Sailaja Polavarapu
             Fix For: 1.1.0


Ranger fails to start when Hadoop core is using LDAPGroupMapping with class not found. This happens when SSL is enabled for ranger admin and "hadoop.security.group.mapping.provider.ldap.bind.password.*file*" property is configured in core-site.xml.
