> Discussed with Natty about LdapGroupMapping, we need to improve it so that:
> 1. It's possible to do different group mapping for different
> users/principals. For example, AD user should go to LdapGroupMapping service
> for group, but service principals such as hdfs, mapred can still use the
> default one ShellBasedUnixGroupsMapping;
> 2. Multiple ADs can be supported to do LdapGroupMapping;
> 3. It's possible to configure what kind of users/principals (regarding
> domain/realm is an option) should use which group mapping service/mechanism.
> 4. It's possible to configure and combine multiple existing mapping providers
> without writing codes implementing new one.
