             Summary: When ldap is opened, I use an ignored case user to login, the page does not respond.
                 Key: KYLIN-3197
                 URL: https://issues.apache.org/jira/browse/KYLIN-3197
             Project: Kylin
          Issue Type: Bug
          Components: General
    Affects Versions: v2.3.0
            Reporter: xingpeng
         Attachments: image-2018-01-25-17-22-39-970.png

When ldap is opened, I create a new user named 'wkh', then I use '{color:red}wkh{color}' to login in, which is normal.
But when I use '{color:red}WKH{color}' to login in, the page does not respond.
I analyze the backgroud code, and find the function of 'org.apache.kylin.rest.security.LDAPAuthoritiesPopulator.getGroupMembershipRoles(String, String)' has problem.
When userDn is "uid=wkh,ou=People,ou=defaultCluster,dc=zdh,dc=com" and username is "WKH", then authorities will be null by the follow code:

{code:java}
Set<GrantedAuthority> authorities = super.getGroupMembershipRoles(userDn, username);
{code}

So I have added 'getAdditionalRoles' function to get the authorities again.
