Github user VipinRathor commented on the issue: https://github.com/apache/zeppelin/pull/2330 @prabhjyotsingh Thanks for reviewing this. > any specific reason for chaning ldapRealm = org.apache.zeppelin.realm.LdapRealm to ldapRealm=org.apache.zeppelin.realm.LdapRealm in all the lines ? Earlier there were lines with mixed spacing, I just wanted to keep it uniform. We can choose any one style that you want. > I notice you have removed these two; > > ldapRealm.contextFactory=$ldapGroupContextFactory > ldapRealm.contextFactory.systemAuthenticationMechanism=simple > > any specific reason? Yes, if you keep the first one, Shiro will throw error that ldapGroupContextFactory is not defined anywhere so can't be used. And in fact, the sample configuration is actually not defining any such ldapGroupContextFactory. Instead `LdapRealm` is using `JndiLdapContextFactory` , so no need to override a contextFactory. For `systemAuthenticationMechanism`, there is neither such configuration available in `JndiLdapContextFactory` nor `LdapRealm` introduced any. Looks like a left over from earlier configuration set, hence removed.
