Peng Xing commented on KYLIN-3197:

Hi [~Aron.tao], I run the latest Kylin code, and I check out my configuration 
by your LDAP document, it has the same, but the user 'WKH' still can not login 
the system, I guess it may be the openldap version problem, so can you tell me 
your openldap version? thanks!

> When ldap is opened, I config the kylin.properties, and give wkhGroup the 
> admin permission.
> {code:java}
> ## Admin roles in LDAP, for ldap and saml
> kylin.security.acl.admin-role=wkhGroup
> {code}
> then I create a new user named 'wkh' whose group is 'wkhGroup', then I use 
> '{color:#ff0000}wkh{color}' to login in, which is normal.
>  But when I use '{color:#ff0000}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={color:#ff0000}wkh{color},ou=People,ou=defaultCluster,dc=zdh,dc=com" and 
> username is "{color:#ff0000}WKH{color}", then authorities will be empty Set 
> 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!
