Edward Capriolo commented on HIVE-78:
-------------------------------------

I wanted to mention one more solution. JDBCRealm. This is pretty well 
established in tomcat. It should be easy to retrofit. It has support for roles.
Password file is a good solution as well. 

Q. Active Directory is an LDAP at its core. What is a case that you need samba 
to get at data in LDAP? It seems like we should be able to support active 
directory and LDAP using JNDI--

I was thinking about 'roles'. hiveuser - Can issue queries kill their own 
queries ,  hiveadmin - can kill users queries
