      Description

      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.
