> 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.
