------------------------------------
Looks like we need to handle the case of null:

> Handle user@domain username under LDAP authentication

> URL: https://issues.apache.org/jira/browse/HIVE-8916
> Project: Hive
> Issue Type: Bug
> Components: Authentication

>
> 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: u...@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
> "u...@domain.foo.com") for looking up privilege rules, etc. As such, any
> domain info in the username should be stripped off.
