> On most LDAP servers the user and group names are case-insensitive. When we
> use {{JniBasedUnixGroupsMappingWithFallback}} and have {{SSSD}} in place, it
> is possible to configure {{SSSD}} to force the group names to be returned in
> lowercase. If we use {{LdapGroupsMapping}}, we don't have any such option.
> This jira proposes to introduce a new {{hadoop.security.group.mapping}}
> implementation based on LdapGroupsMapping which supports force lower/upper
> case group names.
