------------------------------------

Looks like we need to handle the case of null:

> If LDAP is configured with multiple domains for authentication, users can be in different
domains.
> Currently, LdapAuthenticationProviderImpl blindly appends the domain configured "hive.server2.authentication.ldap.Domain"
to the username, which limits user to that domain. However, under multi-domain authentication,
the username may already include the domain (ex:  user@domain.foo.com). We should not append
a domain if one is already present.
> Also, if username already includes the domain, rest of Hive and authorization providers
still expects the "short name" ("user" and not "user@domain.foo.com") for looking up privilege
rules, etc.  As such, any domain info in the username should be stripped off.
