> 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.
> I have test the patch, please review, thanks!
